Appendix:Old Irish class B IV present verbs

Old Irish class B IV verbs (Strachan's A2; McCone's S3 with e vocalism) are derived from Proto-Celtic verbs ending in *-nati, from Proto-Indo-European athematic verbs with a nasal infix before a laryngeal (singular *-né-H-ti, plural *-n-H-énti). They correspond to Ancient Greek verbs ending in -νημι (-nēmi) and to Sanskrit class 9 verbs (e.g. क्रीणाति (krīṇāti, “to buy”), which corresponds exactly to Old Irish crenaid (“to buy”)). The stem-final n is always non-palatalized, and exists only in the present stem; there is no n in the future, subjunctive, or preterite stems of these verbs.

The inflection is almost identical to that of class B I, subtype S1c (canaid type) except that the n remains nonpalatalized even when word-final and B IV shares the first-person singular absolute and conjunct -aim and the second-person singular conjunct -ai with the weak verbs.

A sample verb of this subclass is benaid (“to strike”). The endings are as follows (note that several of the endings are delenited after the root-final n):
