Alternative forms[edit]

  • (palatalized form when the infinitive stem ends in velar consonant): *-ťi


From Proto-Balto-Slavic *-tei, from the dialectal Proto-Indo-European *-tey, the dative or locative singular of *-tis (as opposed to the regular dative *-tey-ey, with a suffix *-tey- in e-grade and the dative singular ending *-ey).

E.g. Late Proto-Slavic *dàti (to give) < Early Proto-Slavic *dā́ˀtei < Proto-Balto-Slavic *dṓˀtei < earlier *deh₃téy < Proto-Indo-European *dh₃téy (and not *deh₃tey-ey), nominative *déh₃tis, from the root *deh₃-.



  1. The ending of the infinitive. Not productive by itself; new verbs were created with a variety of stem-forming suffixes before the ending.
