ون

ـُونَ • (-ūna) m

1. Nominative-case suffix used to pluralize nouns and adjectives, generally masculine ones referring to people. The suffixe changes to ـِينَ‎ (-īna) in the genitive and accusative cases.
2. -ty

• This suffix is mostly restricted to participles, nisbas, and certain nouns of other building types such as the measure فَعَّال (faʕʕāl). Only a handful of nouns not referring to people use this suffix, e.g. سِنُونَ‎ (sinūna) from سَنة‎ (sana, “year”). Most other nouns have broken plurals or use the “feminine” suffix ـَات‎ (-āt). Note that borrowed nouns tend to use the latter even when they refer to people, e.g. بَهْلَوانَات‎ (bahlawānāt) from بَهْلَوان‎ (bahlawān, “acrobat”).

Perhaps from or related to Persian ون‎ (van, “ash tree”).
