instituires

Instituires is a verb form in the Portuguese language derived from the infinitive instituir, meaning to establish or to institute. It is used to express a hypothetical or future action by the second person singular in subordinate clauses. In many grammars it is described as a form of the subjunctive mood, commonly occurring in the future-subjunctive constructions found in Brazilian Portuguese and other dialects.

Etymology and morphology: The form comes from the Latin root institutu- and travels through Old Portuguese into modern usage as part of the conjugation system for verbs of the -ir group. The exact spelling and accenting can vary by variety and orthographic reform, but the function remains as a second-person singular subjunctive form tied to hypothetical or contingent events.

Usage: Instituires appears in contexts such as when introducing a condition or possibility: quando tu instituires uma nova regra, quando você instituires uma comissão, se tu instituires as medidas adequadas. It is more common in formal, legal, or literary registers and in written narratives or official documents where the future-subjunctive mood is preferred for outlining conditions or potential actions.

Related forms and notes: The related verb is instituir, from which instituires is derived. Speakers and writers may choose among regional variants or pronoun choices (tu, você) that influence formality and rhythm. In everyday speech, simpler indicative or other subjunctive constructions may be favored, depending on the region.
