assinou

Assinou is a verb form in Portuguese. It is the third-person singular pretérito perfeito do indicativo (past simple) of the verb assinar, meaning to sign. In English, it corresponds to “he signed” or “she signed,” depending on the subject.

Etymology and form: Assinar derives from the Latin signare, meaning to sign or mark. Assinar is a regular -ar verb, and assinou is produced by adding the past tense ending to the stem assin-. The full conjugation in the pretérito perfeito do indicativo is eu assinei, tu assinaste, ele/ela assinou, nós assinamos, vós assinastes, eles/elas assinaram.

Usage: Assinou is used to describe a completed signing action in the past. It typically appears with direct objects such as contratos, documentos, or cartas. Examples include: Ele assinou o contrato ontem. Ela assinou a ata da reunião. Quem assinou o formulário? The form is rarely used in informal speech in isolation; it appears most often in written text, news, legal documents, and reports.

Related forms: Related words include assinar (to sign), assinatura (signature), and assinante (subscriber). The verb can be followed by prepositional phrases indicating what was signed (por exemplo, consentimento, acordo) and may be combined with adverbs indicating time (ontem, hoje, ontem à noite).

Notes: Assinou is specific to the third-person singular in the past tense. Other tense forms and moods of assinar are used to express different times and aspects.
