marnaid

Old Irish

Etymology

From Proto-Celtic *marnati, from Proto-Indo-European *merh₂-.

Pronunciation

• IPA^(key): /ˈmar.n̪əðʲ/
  • (Blasse) [ˈmar.n̪ɪðʲ]
  • (Griffith) [ˈmar.n̪ɨðʲ]

Verb

marnaid (conjunct ·mairn, verbal noun mrath)

1. to betray
2. to deceive, delude

Inflection

Historically, this verb is expected to belong to present class B IV, as the stem-final n is found only in the present stem, but the palatalization of the rn cluster in the third-person singular present conjunct form ·mairn forms shows that it is in the process of being taken over into another class. In Middle Irish it is often inflected as a weak verb of class A II, as shown by the third-person plural present absolute form mairnit and the third-person singular perfect form ro·mairnestar, in which the n has spread beyond the present tense.

Simple, class B IV present, t preterite, é future, a subjunctive
