rigorosos

Rigorosos is the masculine plural form of the Spanish adjective rigoroso, meaning strict, thorough, or exact in the application of rules, standards, or methods. The term is also used in Portuguese with identical spelling and a similar meaning. The feminine plural form is rigorosas, and the singular forms are rigoroso (masculine) and rigorosa (feminine).

Etymology: The word derives from Latin rigor, meaning stiffness or severity, combined with the suffix -oso to form adjectives.

Usage: In Spanish, rigoroso is used across academic, legal, scientific, and journalistic contexts to convey carefulness and strictness. Examples include medidas rigurosas (strict measures), procedimientos rigurosos (thorough procedures), and una evaluación rigurosa (a rigorous assessment). The plural form rigorosos modifies masculine plural nouns (for example, informes rigurosos); feminine nouns take rigorosas (for example, pruebas riguosas).

In Portuguese, rigoroso and rigorosos are used similarly, and the feminine and plural forms follow the same gender-number rules (rigorosa, rigorosas).
