Concluir

Concluir is a verb used in Spanish and Portuguese with senses centered on finishing, ending, or reaching a conclusion, and also on deducing or inferring from evidence. The etymology traces to the Latin concludere, meaning to close or finish something brought together.

In both languages, concluir is transitive and commonly pairs with a direct object or a subordinate clause. It can mean to finish a task or document (concluir un informe, concluir um acordo) and to reach a decision or end a process. It also appears in logic or reasoning as “to conclude that” (concluir que), indicating a deduction or inference.

Conjugation (selected forms): In Spanish, concluir is an -uir verb with a present tense formed as yo concluyo, tú concluyes, él/ella concluye, nosotros concluimos, ellos/ellas concluyen; the gerund is concluyendo and the past participle is concluido. In Portuguese, concluir is an -ir verb with present forms such as eu concluo, tu concluis (Portugal) or você conclui (Brazil), nós concluímos, eles concluem; the gerund is concluindo and the past participle is concluído. The noun forms are conclusión in Spanish and conclusão in Portuguese, referring to the act or result of concluding.

Notes: The choice between senses of finishing and deducing depends on context. Concluir is frequent in formal, academic, and legal registers, and is often linked to other related terms such as finalização, término, or conclusão.
