On the Constituent Structure of Augmented Plurals in Russian

This article examines augmented plurals in Russian, mostly focusing on those in -ĭj- (e.g., pero/perʲja ‘feather.sg/pl’). The accentual behavior of -ĭj-plurals is sensitive to animacy: while inanimates show stem-final stress, animates appear with inflectional stress. This is explained by different constituent structures: while for inanimates, -ĭj- combines with the stem, animate stems require complex suffix formation so as to not create neuter animates, which are not tolerated in Russian. The position of the accent is then derived from the usual assumptions about Russian stress and the hypothesis that -ĭj- is accented but unaccentable. Other plural augments are also discussed.
