Estabeleci

Estabeleci is the first-person singular form of the Portuguese verb estabelecer in the pretérito perfeito do indicativo, meaning "I established" or "I set up." It is used to describe a completed action in the past, such as creating a rule, founding a organization, or setting up a system.

Etymology and forms: The verb estabelecer derives from Latin stabilire, through medieval Romance languages, with influence from related forms in Spanish (establecer) and French (établir). In Portuguese it is an regular -er verb, and the preterite forms are: eu estabeleci, tu estabeleceste, ele/ela/você estabeleceu, nós estabelecemos, vós estabelecestes, eles/elas/vocês estabeleceram. The noun form related to the action is estabelecimento, and the past participle is estabelecido.

Usage notes: Estabeleci is used for concrete, completed actions in the past. It contrasts with the imperfect form estabelecia, which would indicate a past habit or ongoing action, and with the past participle estabelecido, used in compound tenses or as an adjective. In contemporary usage, Brazilian Portuguese commonly uses você estabeleceu in the corresponding past tense, while European Portuguese more often uses tu estabeleceste or você estabeleceu depending on regional variety.

Examples: Eu estabeleci uma nova política na empresa. Eles estabeleceram acordos com várias organizações internacionais.
