Afirmo

Afirmo is the first-person singular present indicative form of the Spanish verb afirmar, meaning to state confidently, declare, or confirm. It expresses a personal assertion and is used when the speaker presents something as true. The form derives from Latin affirmare, from ad- “toward” and firmare “to make firm.”

In Spanish, the present indicative conjugation of afirmar is afirmo, afirmas, afirma, afirmamos, afirmáis, afirman. Afirmo is used with the understood subject “yo,” and can appear in formal, academic, legal, or everyday discourse to introduce a claim: Afirmo mi compromiso con el proyecto. In legal or sworn contexts, it may precede statements presented as evidence or declaration.

Cognates and related terms exist in other Romance languages. In Portuguese, the equivalent first-person form is eu afirmo. The related noun form in Spanish is afirmación (the act or instance of affirming), and in Portuguese afirmação carries the same meaning. These terms share the same etymological origin in Latin affirmare.

Afirmo, as a linguistic form, is therefore a key element of assertion in Spanish, signaling personal certainty or declaration, and it connects to a family of related verbs and nouns across the Romance language spectrum.
