fechar

Fechar is a Portuguese verb meaning to close, shut, or bring to an end. It covers both literal closure of physical objects (doors, windows, lids, containers) and more figurative closures, such as ending a business deal, a period of time, or a discussion. The verb is commonly used in everyday speech and in formal writing.

Common uses include: fechar a porta (to close the door), fechar a janela (to close the window), fechar um negócio (to close a deal), fechar um acordo (to close an agreement), fechar o ciclo (to close a cycle), and fechar a ferida (to close a wound). The sense can imply completing, finalizing, or sealing. It is also used in idioms like fechar com chave de ouro (to end with a flourish) or não ter nada a acrescentar e fechar a conversa (to end the conversation).

The noun forms related to the act are fechamento or fecho, and the adjective fechado describes something that is closed. In mathematics and logic, fechar denotes the operation of closure on a set.

Grammatical note: fechar is a regular -ar verb and follows standard Portuguese conjugation patterns across tenses, moods, and voices. It is common in both Brazilian and European Portuguese, with regional preferences for formality and pronoun use (for example, você/ele/ela versus tu).
