ني

1. Also used to emphasize attached pronouns and as a copula.
2. هُمْ (hum) becomes هُمُ (humu) before the definite article الـ (al--).
3. Specifically, ـنِي (-nī, “me”) is attached to verbs, but ـِي (-ī) or ـيَ (-ya, “my”) is attached to nouns. In the latter case, ـيَ (-ya) is attached to nouns whose construct state ends in a long vowel or diphthong (e.g. in the sound masculine plural and the dual), while ـِي (-ī) is attached to nouns whose construct state ends in a short vowel, in which case that vowel is elided (e.g. in the sound feminine plural, as well as the singular and broken plural of most nouns). Furthermore, -ū of the masculine sound plural is assimilated to -ī before ـيَ (-ya) (presumably, -aw of masculine defective -an plurals is similarly assimilated to -ay). Prepositions use ـِي (-ī) or ـيَ (-ya), even though in this case it has the meaning of “me” rather than “my”. The sisters of inna can use either form (e.g. إِنَّنِي (ʔinnanī) or إِنِّي (ʔinnī)).
4. ـهِـ (-hi-) occurs after -i, -ī, or -ay, and ـهُـ (-hu-) elsewhere (after -a, -ā, -u, -ū, -aw).
