Appendix:Old Irish class B II present verbs

Old Irish class B II verbs (Strachan's A3, McCone's S2) are derived from Proto-Celtic verbs ending in, which are derived from Proto-Indo-European verbs ending in or  and correspond to the Latin third conjugation i-stems (e.g. ) and Sanskrit class 4 verbs (e.g. ). The final consonant of the stem is palatalized throughout, meaning that any consonant-initial endings also start with a palatalized consonant.

The endings of the class are the same as for class A II, except for the third-person singular conjunct nondeponent, which ends in the stem-final consonant, not in -i as in the weak conjugation.

See Category:Old Irish class B II present verbs for a list of verbs belonging to this class.

Deponent endings
A sample verb for this class is. As with class A II, the deponent verbs of this class take a linking vowel between the stem and many of the endings. The endings are as follows:
