- (palatalized form when the infinitive stem ends in velar consonant): *-ťi
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 *dati (“to give”) < Early Proto-Slavic *dātej < Proto-Balto-Slavic *dōtei < earlier *deh₃téy < Proto-Indo-European *dh₃téy (and not *deh₃tey-ey), nominative *déh₃tis, from the root *deh₃-.
- The ending of the infinitive. Not productive by itself; new verbs were created with a variety of stem-forming suffixes before the ending.
