estabeleceste

Estabeleceste is a conjugated form of the Portuguese verb estabelecer, corresponding to the second-person singular do pretérito perfeito do indicativo. It expresses that you established or set up something at a specific point in the past. In many varieties of Brazilian Portuguese, the corresponding form for the same subject and tense is often rendered as você estabeleceu, while estavas using tu is still common in European Portuguese.

Grammatically, estabeleceste is an active-voice, indicative-mood, simple-past form. The verb form is built from the stem estabelec- plus the endings of the preterite for the tu form. The pronoun tu is typically implicit in the verb form, but can be explicitly included as “tu estabeleceste.” In Brazilian Portuguese, the use of tu is regional, with você estabeleceu serving as the standard second-person past tense in many varieties.

Etymology traces establishing back to a Latin root, stabilire, meaning to make stable. The verb traveled into the Romance languages through Old French estBlir/establir and Spanish establecer, yielding Portuguese estabelecer and its derived forms. The sense broadened from the physical act of making something stable to the more figurative sense of founding, fixing, or determining rules, structures, or institutions.

Usage notes: estabe­lecer and its past forms, including estabeleceste, appear in narratives, historical accounts, and formal prose when describing actions completed in the past. They are also found in instructional or descriptive texts that recount decisions or foundations taken by a specific subject.
