adequada

Adequada is the feminine singular form of the Portuguese adjective adequado, meaning adequate, appropriate, or suitable. It is used to describe nouns that meet required standards or conditions and must agree in gender and number with the noun it modifies. For example, medidas adequadas (adequate measures) or solução adequada (suitable solution).

Etymology and relation to other forms: The term adapts from adequado, which in turn derives from a Latin-rooted lineage often described as adequatus in Latin, indicating something made proper or fitting. The word forms across gender and number follow standard Portuguese adjective agreement: adequado (masculine singular), adequada (feminine singular), adequados (masculine plural), adequadas (feminine plural).

Usage and nuance: Adequada is common in formal, technical, and official writing, as well as in everyday language when precision is important. It conveys that something satisfies the requirements for a given purpose, context, or standard. It can describe actions, measures, information, policies, or recommendations as properly suited to their intended use. Related terms include apropriada, conveniente, suficiente, and idônea, which carry similar senses with slight nuances in emphasis.
