interesarme

Interesarme is the infinitive form of the reflexive verb interesarse, used in Spanish to express that something is of personal interest to the speaker. The base verb interesar means “to interest” and is transitive; adding the reflexive pronoun me forms a sense of becoming interested or taking an interest in something.

In everyday usage, the most common construction with the idea of personal interest is the non-reflexive interesar, with me as an indirect object pronoun: me interesa (it interests me) / me interesan (they interest me). The thing that interests the speaker can be a noun phrase, a clause, or an infinitive: Me interesa la física. Me interesa que llegues a tiempo. Me interesa aprender idiomas.

The infinitive form with the reflexive pronoun, interesarme, appears in phrases that express the act of taking up an interest in something, often with verbs like querer or gustaría: Quiero interesarme por la historia. Me gustaría interesarme en esa materia. This form is used to indicate the speaker’s intention to become more engaged or to begin to take an interest.

Grammatical notes: interesar(se) is a transitive verb; the thing that causes interest is the subject of the sentence, while the person affected is marked by pronouns such as me, te, le, nos, os, les. The reflexive form interesarse emphasizes a change of state or a deliberate act of becoming interested. In present tense, you will see me interesa(n) for singular/plural subjects.
