Irish Conjugation - Irregular Verbs

Irregular Verbs

There are eleven irregular verbs in Irish. Most of them are characterized by suppletion, that is, different roots are used to form different tenses. Analytic forms are indicated by the symbol +. The preterites of many irregular verbs take the nonpreterite forms of preverbal particles, e.g., an (interrogative particle) and ní (negative particle), instead of ar (pret. interrogative particle) and níor (pret. negative particle). Some verbs have different independent and dependent forms in certain tenses; the independent forms are used when no particle precedes the verb, and also after má "if" (open conditional) and the direct relative particle a, while the dependent forms are used after all other particles.
