Proto-Slavic

Alternative forms

(after soft, palatal consonants): *-estь

Etymology

From Proto-Balto-Slavic *-astis, from Proto-Indo-European *-Hostis. Cognate with Lithuanian -astis.There are several theories of origin:

Cognate with Hittite [script needed] (-ašti) (in [script needed] n (dalugašti-, “length”) < [script needed] pl (dalugaeš, “long”, adj.)).
According to Halla-Aho, by double suffixation */-ot-tь/. e.g. *dobrъ → *dobrota → *dobrostь.

Has a reconstructed valence “−” (minus), that is, the accent paradigm c.
