For expressing general or gnomic statements, wnn is used in the perfective, unlike other verbs, which are used in the imperfective for this function.
As wnn has no perfect form, it uses the perfective in situations where the perfect might otherwise be expected.
Existential clauses are formed with wnn in the perfective, typically beginning with jwwn for positive existential clauses or nnwn for negative existential clauses. The negative can also be introduced with the terminative njwnt (usually in dependent clauses) or jwtwnt (usually in noun clauses). Yes-no questions about existence are generally introduced with jnjwwn.
When wnn is used in an inflected form of the suffix conjugation or as a verbal adjective, it can effectively make adverbial predicates (including verbs in the stative) in its clause have the meaning or function of that inflected form, e.g. wn in the subjunctive can give an adverbial predicate a subjunctive meaning or function. Thus, it also allows them to form:
causatives with rḏj, by having a subjunctive wn be the object of rḏj with a following adverbial/stative predicate.
the protasis of a conditional sentence, by having a prospective wnn follow jr with a following adverbial/stative predicate.
Archaic or greatly restricted in usage by Middle Egyptian. The perfect has mostly taken over the functions of the perfective, and the subjunctive and periphrastic prospective have mostly replaced the prospective.
Declines using third-person suffix pronouns instead of adjectival endings: masculine .f/.fj, feminine .s/.sj, dual .sn/.snj, plural .sn.
