Acostarse Conjugation | How to Conjugate Acostarse in Spanish

Acostarse means “to go to bed” or “to lie down.” You will learn its pronominal forms, its main o → ue present pattern, its sense-dependent regular coastal pattern, compound forms, and commands.

Acostarse conjugation at a glance

Acostarse is pronominal in its main “go to bed / lie down” use, so its finite forms require a subject-matched pronominal clitic. Verb type: Irregular. The main learner paradigm has an o → ue change in stressed present forms, while the preterite, imperfect, future, conditional, gerund, and participle use the acost- stem without that diphthong.

Acostarse gerund, past participle, and infinitive

The infinitive names the verb, the gerund helps build progressive constructions, and the past participle is used with haber — “to have” as an auxiliary — in compound forms. With compound forms built with haber, the participle does not agree with the subject.

Form	Spanish	Natural English guide
Infinitive	acostarse	to go to bed / to lie down
Gerund	acostándose	going to bed / lying down
Past participle	acostado	gone to bed / lain down in compound use

Acostarse meaning and essential uses

In its everyday pronominal use, acostarse — “to go to bed / to lie down” — describes putting your own body into a lying position or going to bed. The pronominal clitic is part of this use: Me acuesto temprano. — “I go to bed early.”

With con — “with” — the verb can also refer to having sexual relations with someone, so context matters. Se acostó con su pareja. — “He/She slept with their partner.”

Acostarse conjugation pattern

For the everyday meanings “to go to bed” and “to lie down,” use the diphthong pattern: me acuesto — “I go to bed.” The change does not affect nosotros/nosotras or vosotros/vosotras in the present. RAE/ASALE distinguishes a separate coastal meaning, “to approach the coast,” in which the verb is regular; for example, se acosta a la costa can mean “it approaches the coast.” That regular form is not an alternative for the everyday “go to bed” meaning.
