interesa

Interesa is a Spanish verb form from the verb interesar, meaning to be of interest or to matter to someone. It is the third-person singular present indicative form, used when the thing that interests is a singular noun or an infinitive. The person who is interested is indicated with an indirect object pronoun such as me, te, le, nos, os, or les. For example: me interesa la historia (history interests me); ¿qué te interesa? (what are you interested in?); eso me interesa (that interests me).

In grammar, the subject of a sentence with interesa is the thing that causes interest, while the person who experiences the interest is shown by the indirect object. When the object is plural, the form changes to interesan (e.g., los libros me interesan). The negative form is no me interesa or no te interesa, depending on the subject.

Interesa also appears in constructions where the emphasis is on importance or relevance: "Interesa a la comunidad" means "It is of interest to the community" or "It matters to the community." The related noun is interés, which can refer to interest in the sense of concern or curiosity, or financial interest.

Etymology traces interés back to Latin inter- and esse in interesse, originally meaning to lie between or to be of consequence. In modern Spanish, the verb is used to describe what catches attention or holds importance for someone, while interés as a noun covers both personal interest and financial interest. Reflexive forms like interesarse mean to become interested in something.
