Unveiling the Enigmatic Origins of Sardinian Toponyms

: With the boom in Indo-European (IE) studies among linguists from the early 20th century, toponymic studies on European place names have been largely based on the Proto-Indo-European (PIE). However, historical and archaeological records of non-IE groups, such as the Nuragic civilization of Sardinia, have presented the possibility of pre-IE/non-IE (Paleo-Sardinian) linguistic stratum inﬂuences on certain toponyms in Sardinia, Italy. This article aims to present a meta-study on existing toponymic reconstructions theorized by scholars, while offering a fresh perspective by employing methods of historical phonetic chains and sequences analysis to identify toponyms of interest. Analysis showed that certain Sardinian toponyms contain striking phonetic sequences that are uncharacteristic of PIE, such as *s(a)rd-, *kar-, *-ini, *- à i/*- é i, *#[ θ ]-. Overall conclusions appear to display the merits of (1) PIE and (2) pre-IE/ non-IE theories. Both provide plausible toponymic reconstructions. (1) The accuracy of IE theories is brought into question, as they appear to rely heavily on phonetic links to existing PIE roots, sometimes with a lack of consideration for other contextual or hydro-geo-morphological factors. (2) Conversely, pre-IE/non-IE theories are found to be highly speculative due to the lack of historical data, and knowledge, about the Paleo-Sardinian language.


Introduction
The taxonomic study of place names, also known as toponymy, studies place names using methods of etymological reconstruction. Toponyms encompass the essence of a geographical area and are thus seen as a sine qua non for a place's existence (Tent 2015). The study of toponymy aims to provide us with valuable insights into spoken languages that have been lost to us with the passage of time. Many toponyms are seen as 'linguistic fossils', and are one of the few constants in an era that saw the rise and fall of a great many civilizations. The names are often retained for consistency in cartography as well as simply for convenience. In time, the origins of these names were lost and often misinterpreted or misattributed to local legends and implausible theories. These erroneous concepts are known as false etymologies. In the current section, a background of the reconstructed Proto-Indo-European language (PIE) and its significance in toponymic studies will be detailed. Section 2 of the article will briefly discuss the current linguistic landscape and the hypothesized Paleo-Sardinian language, followed by the motivations of the article in Section 3. Analysis of Sardinian toponyms containing the specific root forms *s(a)rd-, *kar-, *-ini, *-ài/*-éi, *#[θ]and Oristano will be analyzed, with scholarly theories reviewed, in Section 4. Section 5 will provide concluding remarks and a summary review of the findings.
Since the common ancestor of Indo-European languages, PIE, was discovered, it has been the focus of scholars studying ancient languages and language-change processes over the course of history. Consistent attempts have since been made at reconstructing this 'prior' language and its features. PIE was discovered by polyglot Sir William Jones, who was fluent in multiple languages, including classical Latin and Ancient Greek. He noticed the similarities in words between Sanskrit (Vedic Sanskrit-c. 1500-600 BCE; Classical Sanskrit-c. 700 BCE-1350 CE) and Latin (753 BCE-developed into romance languages at The contribution by the Grimm brothers gave rise to the comparative method of studying languages and reconstructing hypothesized proto-languages, which comprise languages that lack existing written records (Fowler 1957). The popularity of PIE studies has led to the development of the substantial lexicon compiled in Austrian-German comparative linguist Julius Pokorny's (1959) Indo-European etymological dictionary: Indogermanisches etymologisches Wörterbuch, with a later revised version by the Dnghu Adsoqiationthe Indo-European Language Association (Pokorny et al. 2007).

Sardinia and the Nuragic Civilization
Sardinia (Figure 2) is one of the twenty regions of Italy, situated to the west of the Italian peninsula. The island is, notably, the second-largest in the Mediterranean Sea. Sardinia is particularly intriguing to scholars due to its rich archaeological remains and history linked to ancient societies. Archaeological data revealed that Sardinia has been inhabited since the Upper Paleolithic and Mesolithic periods, giving the island its reputation as one of the most ancient bodies of Europe.
The earliest evidence of human settlements appears to be that of the Ozieri people, from c. 3200 to 2800 BCE. By c. 2000 BCE, new inhabitants from the Beaker culture appeared, which later developed into the Bonnanaro culture of Sardinia (1800-1600 BCE). Subsequently, the culture gradually became more advanced, and the people began building large conical dry-stone towers known as the nuraghi.

Sardinia (Figure 2) is one of the twenty regions of Italy, situated to the west of the Italian peninsula. The island is, notably, the second-largest in the Mediterranean Sea. Sardinia is particularly intriguing to scholars due to its rich archaeological remains and history linked to ancient societies.

By c. 2000 BCE, new inhabitants from the Beaker culture appeared, which later developed into the Bonnanaro culture of Sardinia (1800-1600 BCE). Subsequently, the culture gradually became more advanced, and the people began building large conical dry-stone towers known as the nuraghi. The civilization that created these historic marvels was termed the Nuragic civilization, as a namesake for the nuraghe structures. The Nuragic civilization thrived in Sardinia during the Bronze Age from 1900 The nuraghe have been pivotal in giving us a glimpse into the workings of the Nuragic society, which would otherwise be lost in time, as well as into the innovative usage of materials and complex construction techniques. The magnificent sight of these widespread structures has cemented the island as a popular tourist attraction. There are currently around 7000 nuraghi in total (an average of 1 per 3 square kilometers), with experts estimating the original number to be closer to 10,000 (Vacca et al. 1998). In particular, UNESCO lists the well-preserved village of Barumini ( Figure 3) as one of its World Heritage Sites. The site contains the majestic 18.5-meter-tall Su Nuraxi Nuraghe, which houses intricate chambers and a spiral staircase, lined with surrounding subsidiary towers (Su Nuraxi Di Barumini 2021).
Information about the Nuragic people is scarce. Despite the best efforts of scholars and archaeologists from around the world, no evidence of a writing system or written texts has been uncovered thus far. However, some insights into the lives of the Nuragic inhabitants can be gathered from ancient Egyptian sources containing documented references to their culture and lifestyle. Ancient Egyptian inscriptions from the 14th to 12th century BCE referred to the Nuragic inhabitants as the Shardana, "people of the sea" or "sea people" (Ugas 2016). Other physical and cultural physiognomic features that appear to link the ancient Sardinians to the Shardana include genetic data, aspects of economy and trade, weapons, literary references, and Nuragic materials exported or imitated across the eastern Mediterranean lands (Ugas 2016). Ancient sources such as Homer's Odyssey and the works of Simonides of Ceos suggested that the early 'sea people' of Sardinia engaged in attacking and raiding regions, mainly Egypt and Mycenaean sites. In the early 20th century, archaeologist Antonio Taramelli (1982) conducted excavations in the Sardinian Nuragic sites. He discovered unique bronze figures, which show warriors donned in kilts, similar to depictions found in Egyptian temples. Taramelli thus postulated that the ancient Sardinians were linked to the Shardana, although other scholars have contested this hypothesis. Giovanni Lilliu (1983) believed the clothing to have been imported by Mycenaean artifacts have also been uncovered in Sardinia, alluding to Nuragic trade and contact with other civilizations in the Bronze Age (Blake 2015). Since the 1950s, archaeological excavations have uncovered numerous bronze sculptures depicting important personnel such as warriors and leaders, animal motifs, and vehicles of transport such as boats, as shown in Figure 4. Remnants of ancient temples and other religious landmarks have also provided scholars with additional insights into the religious beliefs of the Nuragic people. Patton (1996) hypothesized that the Nuragic people had significant internal social competition due to geographic and social isolation from other communities. These internal pressures may have motivated the people to construct the nuraghi, explaining the seemingly disproportionate effort required in the building process, considering the impracticality of these structures, similar to the elaborate moai structures found on Easter Island today. Archaeological findings and records from external contacts during the Late Bronze Age (LBA) also appear to describe an economy centered on traditional resources, such as the rearing and farming of livestock. Scholars believe that the lack of advancement and diversification within the economy, such as trading of metals or exotica, could have caused the ultimate balkanization and migration of the Nuragic people, eventually leading to the end of the Nuragic era and the abandonment of the nuraghi (Blake 2015).
Upon inhabitation by the Phoenicians in the 9th century BCE, ships became the main mode of transport between continental regions, and Sardinia's location became an ideal port for passing ships. Its prime geographical location, centered in the western Mediterranean, allowed for a flourishing maritime network and booming economy, despite its isolated location. According to Dyson and Rowland (2007), the Phoenicians established an early trading relationship with Sardinia from the 8th to 7th century BCE, integrating it with the vast Mediterranean trading networks from Lebanon to Iberia. The Sardinian trade boomed upon Carthaginian (Punic) settlement on Sardinia from the 6th century BCE until the end of the First Punic War, when the Romans conquered the island (van Dommelen et al. 2017;Dyson and Rowland 2007).

The Paleo-Sardinian Language
Sardinia's linguistic landscape was categorized as diglossic by sociolinguists, starting from the Italian unification in 1861 up to the 1950s. Italian was designated as the language of official administration and education, while Sardinian (or Sard) and other minority languages became the local languages used in non-official and casual domains (Sole 1988;Loi Corvetto and Nesi 1993). However, since the 1950s, Italian has become ever more prevalent even in casual speech, triggering fears of possible language endangerment or the future extinction of the Sardinian language and other minority languages in Sardinia (Tufi 2013).
The Sardinian language is a diasystem that includes several varieties and sub-varieties that have not gone through linguistic or national unification, but contain similar linguistic, phonetic, grammatical, and lexical elements ( Figure 5). Languages are grouped via methods of linguistic typology, identifying similar grammatical and structural features (Tufi 2013). The main linguistic variants are Logudorese (highlighted in yellow) and Campidanese (highlighted in dark orange). Other minority languages outside of the Sardinian language group include Catalan and Ligurian (Tufi 2013).
Some languages spoken in Sardinia are linked to Corsican and not considered varieties of the Sardinian language. They include: Gallurese (highlighted in green), spoken in the northern part of the island, a Corsican-Italian-type language which appears to show some contact with Corsica and the Corsican dialect (Blasco Ferrer et al. 2017), and Sassarese (highlighted in light green), a variety of Italian spoken in Sassari and nearby towns.
Analysis of the language features of Sard revealed that it is a lexically and linguistically close descendent of Latin (Putzu 2019). However, it appears that Sardinian differs significantly from most other Romance languages, with sources often categorizing Sardinian as a separate linguistic group. Although Sardinia is part of Italy, non-Sardinian Italians tend to display a not always neutral perception of the local language (Tufi 2013). This perception dates back to earlier recorded history. In his work De vulgari eloquentia, written during the late Middle Ages (c. 1302-05 CE), the Italian poet Dante Alighieri

The Sardinian language has been observed by linguists to contain specific pre-Latin elements, significantly uncharacteristic of Latin, likely indicative of unknown language influences, before the Latinization of Sardinia (Pittau 1995). Although some Punic (Phoenician) links have been identified, a large portion of the language is still linguistically incompatible with known languages. This suggests the heavy influence of a different language. Linguists have termed this mysterious language 'Paleo-Sardinian'. Without any written findings or specific data on Paleo-Sardinian, little can be concluded about the specifics of the language, such as its origins and genetic links to other languages, except that it was possibly spoken by the Nuragic people. However, specific toponyms can provide us with some linguistic forms and features of the language. Despite the conclusions that these forms were unrelated to the Indo-European language family, many scholars continue to debate the origins of the language and a consensus has yet to be reached.

Motivation and Methodology
Upon the discovery of PIE, Indo-European scholars have attempted to reconstruct Sardinian toponyms, with attribution to hypothesized IE origins. As with any linguistic element in a language, toponyms would be consistent with phonetic laws. However, there are toponyms present that are 'problematic' in nature and do not appear to conform to PIE linguistic laws, which could signal a pre-IE or non-IE origin. Some examples of pre-IE/non-IE languages include ancient Egyptian, Sumerian and Akkadian, pre-Anatolian (e.g., Hattic), pre-Greek substrates (e.g., Minoan), pre-Italic languages (e.g., Etruscan), Paleo-Sardinian (also known as the 'Nuragic language') and an existing descendent of pre-Celtic language-Basque, spoken today in northern Spain and southwestern France. Pre-IE root forms have been proposed in recent studies. A methodological example includes the pre-IE root *borm-, postulated by Perono Cacciafoco (2015b) to account for the origins of a prehistoric toponymic system.
Toponyms containing uncommon linguistic elements uncharacteristic of PIE (e.g., in its phonetic or morphological structure) could be indications of probable linguistic substrate influence from a pre-IE/non-IE language and should be considered when toponymic research is conducted in these language-specific regions. With incomplete data about the Paleo-Sardinian language, it is nearly impossible to reach a definite conclusion on the origins of the language and, consequently, the toponyms themselves. However, the lack of information has not deterred linguists and historians from devising etymologies and theories of these place names.
This article aims to study these 'problematic' toponyms and provide a systematic review and analysis of the theories from both the pre-IE/non-IE and IE-based toponymic reconstructions raised by scholars. This paper intends to address the issue of the lack of comprehensive studies on the topic written in English and to present not very well known Italian sources to a wider audience. The focus will be on Sardinian examples that could show probable influences from pre-IE linguistic stratums. For a more balanced analysis, methods of linguistic analysis on phonetic chains and root forms will be applied to identify names with particularly ambiguous or non-IE linguistic features.

The root *s(a)rdis widely used in Sardinia today and has also been referenced in many historical sources and documents (Table 1), solidifying its status of linguistic stability.

IE Theories (Lydian Theory; Paleo-Sardinian Theory)
The main IE theory brought up by multiple scholars is that the root may be pre-Roman in nature, originating from Lydian, an extinct western Anatolian Indo-European language attested from 700-200 BCE. Lydia was an ancient civilization that existed between 1200 and 546 BCE in the Asia-Minor region located in present-day Turkey. Its location in 540 BCE is shown in Figure 7. Pittau (1995Pittau ( , 2001 hypothesized that the Nuragic people of Sardinia were linked to the Etruscans and descended from populations in Lydia. He evidenced his claims by referencing Plato's Timaeus, where Plato stated that Sardinia and its inhabitants, 'sardianoi' (Ancient Greek: Σαρδιανοί), derived their proper name from Sardis (Sárdeis, Ancient Greek: Σάρδεις), the capital of Lydia, and, thus, the Nuragic people were the Sardianói of Lydia (Pittau 2001).

Another toponym whose origins appear to have yielded strongly divided opinions among scholars is the capital of Sardinia, Cagliari. Cagliari is located south of the island overlooking the center of Golfo degli Angeli ("Bay of Angels") and is situated atop seven hills.

IE Theory
Pittau (2018) noted that archaeological findings date the inhabitation of Cagliari back to the Eneolithic period and likely the Neolithic. He claims that it is, therefore, unlikely that the city's name was created much later in history, upon the arrival of the Phoenicians. Analyzing Pittau's points, it is probable that the Phoenicians could have claimed ownership of the name to express their power and control over the city and in an attempt to 'erase' the prior history of and traditions of the Paleo-Sardinian speakers (who were possibly related to the Nuragic people). Pittau (2018) builds on Wagner's (1950) Paleo-Sardinian theory that 'Cagliari' originates from the Proto-Sardinian Karalis, suggesting that Karalis could mean 'the fortress' or 'the stronghold', with associations to the hill in its district of Castello. He added that this geo-morphological reference is not an isolate. The city Castel di Castro (modern name: Casteddu), synonymous with the hill of Cagliari, appears to be linked to the name as well.
An alternative theory put forth by Pittau (2018) is that the name could be connected to the Proto-Sardinian appellative cacarallái, crialléi, crièlle, chirièlle, ghirièlle, meaning 'wild (yellow) chrysanthemum', and linked to other related words, such as those shown in Table 2. He ultimately concluded that the island could have been named after the color 'yellow', from Paleo-Sardinian sources. He explained that the city was named in reference to the yellow tinge of the rock of the stronghold 'il Castello' and that the color was supposedly more visibly striking in the past compared to today.

The village is famous for 'Su Nuraxi di Barumini', one of the most famous Sardinian archaeological sites, containing some of the most prominent nuraghi structures. This historic location, the village of Barumini, has caught the attention of many scholars and the origins of the name 'Barumini' have been heavily debated. IE scholars, in particular, utilized the method of comparative analysis, and examined various attested and reconstructed roots to derive theories connected to Greek or PIE. This affix appears to be a common linguistic feature found in many toponyms in the southwestern region of Sardinia, including Barumini. Multiple sources have proposed that the proparoxytone feature of *-ini may be of non-IE (mainly African or Iberian) origins Blasco Ferrer 1984;Rohlfs 1952 Pittau (2018) proposed that the name Barumini is linked to the Greek adjective barúmēnis ('angry/vindictive').

Dedola pointed out that the Sumerians referred to Sardinia as Sardū (formed by: sar 'garden' + du3 'all'), which means 'a whole garden' . Dedola asserts that 'Sardinia' was referred to as such due to the abundance of greenery in Sardinia, relative to the desert environment of Mesopotamia.
Dedola's theories, however, have been deemed to be highly controversial by scholars and believed to be paretymological rather than comparative in nature, often based on criticized anti-Indo-European theories by the Italian linguist Giovanni Semerano (Semerano 1994).

Root *kar-
Another toponym whose origins appear to have yielded strongly divided opinions among scholars is the capital of Sardinia, Cagliari. Cagliari is located south of the island overlooking the center of Golfo degli Angeli ("Bay of Angels") and is situated atop seven hills. Scholars believe the city was built and established by the Phoenicians in the 8th or 7th century BCE. Latin poet Claudian wrote, in his 4 th century AD work De Bello Gildonico, that Cagliari was 'founded by the powerful Phoenicians of Tyre' (Pittau 2018). After the First Punic War (c. 264-241 BCE), Cagliari was conquered by the Romans. Cagliari's Punic name was Karaly (Punic: ) and Latin name was Caralis (Wagner 1950). However, scholars believe the name to be not Punic in origin, but likely to have existed even before the arrival of the Phoenicians.

Non-IE Theory
Blasco Ferrer (2010) proposed that the root *barin Barumini occurred in various Iberian inscriptions from the northeastern alphabet. Other examples of Sardinian words with a hypothesized link to the root *barare gorri ('red') and Barumele (Iberian mele). He also brought up the Greek word βάρις ('fortified center with tower'), which is semantically probable to be in relation to the nuraghi megalithic structures. This strengthens the theory that there was significant linguistic contact between the regions of the western and eastern Mediterranean, with Sardinia located in the middle.

IE Theory
He stressed that the suffix -éi is by no means any contracted form of the Latin -ētum. Specific Italian dialects such as Piedmontese contain the form *-ei (i.e., Par-ei) instead of the Italian *-eto, although they both form phytonymic collectives. Specific Cisalpine varieties such as -ei and -eto are possible. Pittau (2018) suggests that the name Baunéi is genetically related to the Greek word baũnos/baunós, meaning 'furnace used for cooking lime or for metal melting and purification'. The village is known to be calcareous, with historical data and records showing that copper and iron mines existed in the nearby region until the 19th century. Pittau, however, acknowledges that *-éi, an accented vowel combined with an attached paragogic vowel, is most likely a Proto-Sardinian relic form found in various Sardinian toponyms. The suffix appears to have resisted the Latinization of the Sardinian language that occurred upon Roman conquest. In short, Sardinian names ending with *-éi are a combination of a Latin base root with a Paleo-Sardinian/Nuragic suffix form.

IE Paleo-Sardinian Theory
The suffix *-éi also appears in other Sardinian terms related to geomorphological features. According to Pittau (2003Pittau ( , 2021, the Sardinian word golléi ('mountain/hills') corresponds to the Latin collis ('hill'). It is evident that there is a phonetic similarity between the two cognates, but *-éi appears to be an unexplained suffix addition to the Sardinian term.

Roots Beginning with #[θ]-
Thìscali is the name of a mountain (oronym) located between the Supramonte of Oliena and the commune of Dorgali. It is also the namesake of an ancient Nuragic village and a famous archaeological site located within the mountain. The ancient village was inhabited around the 1st century BCE, but the first modern record and documentation were by Italian historian Ettore Pais in 1910 (Moravetti 1998). The village was built in a crater within the mountain and contained 40 ancient huts, some of which can still be seen today ( Figure 10). Despite the steep and challenging 3-or 4-h hike required to reach the site, the area remains a popular Sardinian tourist destination. The *th-/*#[θ]-root consonant of the village has proven to be an enigma to scholars, attracting various convincing and probable views. Thìscali is not the only region with this prefix. Other Sardinian place names, such as Thìscali, Nuraghe Thorcodossile (in Oliena), Thorra (at Lodè), also contain this unique phonemic feature.

Oristano
Oristano is a popular Sardinian tourist destination and a great medieval city. An abundance of nuraghi is scattered across the region, most notably the famed Nuraghe Losa, dated to c. 1500 BCE, around the period of the Middle Bronze Age and shaped like a tholos tomb (Andrews 2004;Christiani and Maric 2011). The Oristano region was well-populated in Nuragic times, but historical records of the region were mostly written by the Phoenician colonists from Tyre, who arrived in the late 8th century BCE, subsequently establishing the city of Tharros. Under the rule of the Phoenicians, the region flourished and Tharros established itself as western Sardinia's de facto capital . However, constant raids by Saracen tribes led to the subsequent abandonment of the city in 1070 AD. The people decided to move inland, settling in a region they named 'Aristianis', the exact location of Oristano today (Christiani and Maric 2011).

IE Theories
The most prominent false etymology is linked to a popular Sardinian myth and legend (Sardinialinks 2020). The legend was set in Tharros, an ancient Phoenician city that preexisted Oristano. King Joneto, the ruler of Tharros, captured Zulemma, the daughter of a raiding Saracen (a blanket term for Muslims during the Middle Ages). He fell in love with Zulemma but she would only accept the marriage on the condition that Joneto builds a city in place of the 'Golden Pond' located near Tharros. Facing this impossible task, Joneto ultimately sought the help of a devil named Luziferru and a contract was drawn up-the task would be performed in exchange for his own soul, as well as Zulemma's. The water was expelled and the city of Oristano was thus conceived, with the name deriving from Stagno Dorato 'Golden Pond', Lo Stagno dell'Oro 'The Pond of Gold': from Ori (=oro) 'gold' + stano (=stagno) 'pond'/'swamp'. The story concludes on a happy note, as Joneto manages to seek assistance from the Virgin of the sanctuary of the Madonna del Rimedio, who stole the contract away from the hands of the devil, thus voiding the agreement.
Though an intriguing story, according to 'La leggenda di Oristano: il patto tra Joneto e Luziferu per la sua costruzione' (Sardinialinks 2020), the etymology has been largely proven to be historically improbable (on top of the fact that the content is largely mythical in nature). A more factually attested account is that Oristano was founded in the 11th century AD by Judge Orzoco from Tharros. He and some other men were looking for areas to be shielded from the Saracen attacks in the city. They ultimately took shelter at a place with ponds and swamps and settled there, naming the place Oristano in reference to the landscape filled with ponds.
The false etymology of 'golden pond' has been acknowledged on the official website ( Figure 12) of the city of Oristano (Comune di Oristano 2021) and cited as a reason for the integration of a pond in the design of the Oristano municipal coat of arms (Comune di Oristano 2021).  Besides the 'golden pond' theories, other scholars provide different ideas. Pittau (2018) hypothesized that Aristianes could have been pronounced, according to Byzantine pronunciation, as Aristeanes. He believes that this is proof of clear compatibility with the name Aristaeus. According to Diodorus (Diodorus and Peter Green 2006), Aristaeus is an Ancient Greek mythical character with multiple sections of his story and his cults set in Sardinia. According to Pittau, therefore, Aristianēs límnē, "Oristano's pond/swamp", or Aristianēs limēn, "Oristano's harbor", could be connected to a Latin form villa Aristaeiana, "Aristaeus' village". However, many scholars believe that these links proposed by Pittau are largely unsubstantiated. Besides the 'golden pond' theories, other scholars provide different ideas.

Borghi (2021b) provides a personal comment with a differing analysis of the toponym, reconstructed on a phonetic basis. Oristano (Sardinian Aristànis) looks like the Latin name for the estate of the gēns Ărȋstȋă, but it could be a pre-Roman place name, possibly a locative plural form of the corresponding 'superlative' Besides the 'golden pond' theories, other scholars provide different ideas.

The theory focuses largely on phonetic reconstructions. Though some show plausible links to the hydro-geo-morphology of the specific region, reconstructions such as the one for Oristano above, 'having attached/faithful places (strongholds, fortresses)', appear to be somewhat arbitrary as long as they postulate a dominant relationship between prehistoric Oristano and the nuraghes nearby.
Archaeological findings from Tharros suggest that the city dates from the 9th to 8th century BCE and was abandoned in the late 11th century CE when the people from Tharros moved to Oristano instead. There is a 2000-year difference between the conception of Tharros versus that of Oristano. The possible names of any settlements pre-existing in the vicinity of Oristano are presumed to have been lost. As such, 'Oristano' remains the key toponym that scholars can linguistically analyze.

Conclusions
In conclusion, the case study of Sardinian toponyms, s(a)rd-, kar-, -ini, -ài/-éi, #[θ]and Oristano, for the purposes of this article, give us a glimpse into the different languages that may have left a linguistic 'mark' on the island's toponyms. Without additional findings providing linguistic insights on the proto-language of the Sardinians, prior to the arrival of the Phoenicians, we may never be able to fully decipher the etymologies of most of these enigmatic names. However, it is insightful to analyze the theories and thought processes of scholars who have attempted to figure out the true origins, despite the limited amount of data at hand. Most scholars tend to have strong allegiances to PIE versus pre-IE/non-IE theories. This article attempts to provide a balanced view of the differing opinions and to derive the merits and shortfalls of some of these hypotheses. All in all, even though IE theories may have been supported by documented material, such as in Roman literary works, there are many Sardinian toponyms, likely pre-Roman, that cannot be explained through IE. There is little doubt that there was a thriving society and most likely a language of communication during this time, likely influencing the linguistically unique Sardinian language varieties still spoken today. The different linguistic substratum of Sardinia since the Bronze Age or earlier, could have possibly been 'fossilized' in these Sardinian place names. Future attempts at Sardinian toponymic reconstruction should take these factors into account to provide etymologies of greater historical and linguistic accuracy.
