-ঈ

From Persian -ی.

-ঈ • (-i)

1. (in nouns) one from, belonging to, relating to, or like
2. (in adjectives) coming from, related to, like

   ‎পাকিস্তান (pakistan, “Pakistan”) + ‎-ঈ (-i) → ‎পাকিস্তানী (pakistani, “Pakistani”, adjective)

• -উৱা (-ua)
• -আ (-a)
• -ঈয় (-io)
• -ঈয়া (-ia)
• -আন (-an)
• -ইছ (-is)

• For the relational suffix, borrowed from Sanskrit -ঈয় (-īẏa), from Proto-Indo-European *-iHyos.
• For the possessive suffix, borrowed from Sanskrit -ইন্ (-in), from Proto-Indo-European *-inos.
• For the feminine suffix, borrowed from Sanskrit -ঈ (-ī), from Proto-Indo-European *-ih₂.

The first two uses were reinforced by Prakrit -𑀇𑀅 (-ia), from Sanskrit -ইক (-ika), from Proto-Indo-European *-i-kos. They were also possibly influenced by the unrelated Classical Persian ـی (-ī) and Arabic ـِيّ (-iyy).
