In imperfect of double verbs one of the double letters is omitted.
[[TODO]]==Imperfect of 1-נ== For 1-נ verbs the letter נ is omitted after prefixes in imperfect. נ is also sometimes omitted in imperative of 1-נ verbs. In infinitive or these verbs the first נ in the root is omitted and added ת after the root. Some of the verbs 1-י are declined in the same way as 1-נ. ==Imperfect of 1-א verbs== In the first person, singular of 1-א (having א as the first letter of the root) verbs that א is omitted (so leaving only one א instead of two consecutiveאא).
