-iās

1. accusative feminine plural of -ius

• -jas (after vowels)
• -ỹs (under stress)

From Proto-Balto-Slavic *-jas; which also gave Latvian -̧s, -̧š – compare žálias : zaļš (“green”); tùsčias : tukšs (“empty”). Also related is the Proto-Slavic masculine *-ь. Ultimately, a thematised variant of i-stems (see -is), either of Proto-Indo-European age (cf. *-yós), or of more recent formation. Under stress, *-iós gave Lithuanian -ỹs; see for more.
