ideia

Ideia is a feminine noun in Portuguese that refers to a thought, concept, or plan that arises in the mind. It can denote a mental image, a general notion, or a proposed course of action. In everyday language, people say “Tenho uma ideia” to express a thought, or “Qual é a tua ideia?” to ask for someone's plan or suggestion.

Etymology: The word comes from Latin idea, itself from ancient Greek idea from eidos, meaning form or appearance. It passed into Romance languages through Latin and Old French idée, and was incorporated into Portuguese as ideia. The modern spelling reflects the common -eia suffix used to form abstract nouns.

Usage and nuance: Ideia is commonly used for everyday or informal notions, while conceito or teoria may be preferred for more precise or formal definitions. The plural is ideais? No, ide as: ideias. Common collocations include ideia original, ideia brilhante, ideia de negócio, and ideias contrárias. In philosophical contexts, ideia can denote a mental representation or an abstract form; in cognitive science, it appears in discussions of ideation and thinking processes.

Related terms and cross-language note: Related words include ideação (the act of forming ideas) and ideário (a collection of ideas or an ideological framework). Cognates in other languages include English idea, Spanish idea, French idée, and Italian idea, all tracing to the same ancient root.
