Tancar

Tancar is a Catalan verb meaning to close, shut, or seal. It covers both physical closure (tancar una porta, tancar una finestra) and the closing of abstract or figurative things (tancar un acord, tancar una sessió). It can also be used reflexively, as in tancar-se, to close oneself off or to shut oneself in.

As a regular -ar verb, tancar follows the standard conjugation pattern of Catalan -ar verbs in all tenses and moods. The language has formed participles from the verb: the past participle tancat, used as adjective or in compound tenses; the present participle tancant, used in continuous constructions.

Derivatives and related forms include the noun tancament, meaning closure or shutdown, and the adjective tancat, meaning closed. The gerund form tancant is used in phrases indicating ongoing closing actions.

Tancar is widely used across Catalan-speaking regions, including Catalonia, the Valencian Community, the Balearic Islands, and parts of Aragon. It is the standard term in both everyday speech and formal writing for the act of closing something, as well as for finalizing or concluding processes, events, or negotiations.
