Annullare

Annullare is an Italian verb meaning to cancel, annul, or void. It is used to indicate terminating the validity or effect of an event, order, contract, decision, or other action, making it non-binding or revoking it.

Etymology traces annullare to Latin annullare, from nullus meaning none. The word entered Italian as a regular first-conjugation verb, part of a family of terms related to nullity and removal in law and administration.

Usage and nuance: annullare is transitive and takes a direct object (for example, annullare un appuntamento, annullare un contratto, annullare una decisione). In legal and administrative contexts it conveys nullification of rights or obligations. The related noun annullamento denotes the act of cancellation or annulment, while cancellazione and invalidazione are synonyms with slightly different connotations depending on context.

Conjugation: annullare is a regular -are verb. Present indicative forms include io annullo, tu annulli, lui/lei annulla, noi annulliamo, voi annullate, loro annullano. The past participle is annullato, used with avere to form compound tenses (ho annullato, hai annullato, ha annullato, etc.). Other tenses mirror standard -are conjugation patterns, such as annullavo, annullavi, annullava in the imperfect, and the subjunctive forms like che io annulli.

In everyday use, imperative forms appear as annulla (tu) or annullate (voi); in user interfaces the common label for canceling an operation is Annulla, the imperative form, not the infinitive.
