-ավուն

• -աւուն (-awun) — traditional orthography
• -ավը^ին (-avəⁱn) — Maragheh
• -ավան (-avan), -ա̈վա̈ն (-ävän) — Agulis

The origin is unknown. Confined to Eastern dialects, with the earliest attestation in the 17th century.[1] Ačaṙyan remarks that derivation from Old Armenian -ագոյն (-agoyn) (of Iranian origin) is impossible, because no գ (g) → վ (v) sound change is known in the dialects. But perhaps that change occurred within an Iranian language, where such a change is known, and thence was borrowed into Armenian.

Compare also Central Kurdish -ئەوِن (-ewin), forming adjectives from nouns.
