Estrito

Estrito is a Portuguese adjective that means strict, rigid, or exact. It is used to describe standards, rules, or behavior that are rigorous and uncompromising, as well as to characterize procedures, measures, or conditions that are tightly defined. The term often appears in formal or official language, where precision and rigor are emphasized.

In legal contexts, estrito appears in the formula "em estrito cumprimento do dever legal," which translates to "in strict compliance with the legal duty." This phrase is used to justify actions taken by public agents within the limits of their lawful authority and to denote a defense based on legitimate obligation rather than illicit intent. The expression underscores that the conduct occurred within the bounds of formal duties, not outside them.

Another common usage is the locution "em sentido estrito" (in the strict sense), contrasted with "em sentido lato" or "em sentido amplo" (in a broad sense). These distinctions help clarify whether a term is being used narrowly or more generally in legal, technical, or academic writing.

Etymology traces estrito to Latin strictus, meaning tight, drawn tight, or rigid, itself derived from the verb stringere, to bind or compress. The word spread into Portuguese retaining the sense of rigor and exactness.

Synonyms in Portuguese include rigoroso, severo, rígido, preciso. Related contrasts are established with estreito (narrow or close) to avoid confusion between strictness and physical tightness.

Estrito appears primarily in formal, administrative, or legal texts, and remains a standard term in both Portugal and Brazil for conveying rigor, precision, and obligation.
