opuestas

Opuestas is the feminine plural form of the Spanish adjective opuesto, meaning "opposite" or "opposed." It is used to describe feminine plural nouns that denote opposite positions, directions, ideas, or relations. The masculine singular form is opuesto, and the masculine plural is opuestos; the feminine singular is opuesta.

In everyday Spanish, opuestas appears in phrases such as ideas opuestas, posturas opuestas, or lados opuestos, to indicate contrast or opposition. As a linguistic term, opuesto is closely related to antonym, and in semantics it marks polarity or opposition between concepts. The Latin roots are oppositus, from ob- “against” plus ponere “to place,” hence the sense of something placed against or opposite.

In formal language, the term functions primarily as an adjective, agreeing with the noun it modifies. The noun form for “opposite” is often el opuesto or la opuesta (masculine or feminine respectively), used when referring to the opposite item or concept as a thing rather than a descriptor.

Beyond grammar, opuestas can appear in mathematics, logic, or philosophy to describe opposing values, positions, or viewpoints in a pair or discussion. The term is commonly used in contrastive discourse, rhetoric, and cultural contexts to frame differences and alternatives.
