Acostarse Conjugation in Spanish | Present tense, past tense

Acostarse conjugation signifies ‘to sleep.’ This lesson also demonstrates how to conjugate this verb in the present subjunctive tense using examples from real-life interactions. Thus, if you’re exhausted after a long day, and it’s time to retire. This situation frequently reminds you of your mother’s advice: ‘I hope you get to bed early enough.’ Or maybe it’s just the middle of the day, and you need to relax. So, even if you can’t go to bed to sleep, you can always lie down. You’ve probably heard doctors remark, ‘It’s advised that you go to bed early to feel refreshed.’ Acostarse (ah-Kohs-TAHR-she) is a Spanish verb that meaning ‘to go to bed.’

As you can see, it ends in se, indicating that it is a reflexive verb. Thus, the term reflexive refers to going to bed being performed by and for the individual doing the action. When your mother says, ‘I hope you go to bed,’ or your doctor says, ‘It is suggested that you lie down,’ we get the present subjunctive. However, in Spanish, the subjunctive verb form is not the same as the present tense. Because the form changes, we study the conjugation of costars in the present subjunctive.

Before we go into its conjugation, there are a few things we need to know about acostarse:

The -se in the infinitive indicates that this is a reflexive verb, which means that the action is performed by and for oneself. In Spanish, we must include a reflexive pronoun IN FRONT of every form when conjugating a reflexive verb. These pronouns are (in subject order): me/te/se/nos/os/se. Since acostarse is a stem-changing verb, the stem vowel changes in the present tense. Hence, to conjugate, use the irregular stem access- for all forms EXCEPT Nosotros/as and Nosotros/as.

Pronunciation Translation
yo me acuesto (meh ah-KWEHS-toh) I go to bed
te acuestas (teh ah-KWEHS-tahs) you go to bed
se acuesta (seh ah-KWEHS-tah) he/she goes to bed –
you (formal) go to bed

se acuestan (seh ah-KWEHS-tahn) they go to bed /

Acostarse Conjugation Reflexive

You’ll note that the reflexive pronoun se appears in the infinitive form of acostarse. Hence, this shows that it is a reflexive verb, meaning that the action returns to the subject who does it. For example, yo I acuesto can be translated as “I lay myself down” or “I put myself to bed.” This verb is used in phrases such as Ella se acuesta temprano (She goes to bed early) and Nosotros nos acostamos en el piso (We lay down on the floor). Moreover, this verb can also be used metaphorically to indicate having sexual contact with someone or “sleeping” with someone. El hombre se acostó con su Novia, for example, would be translated as “The man slept with his girlfriend.”

Acosta, like mortar, is a stem-changing verb. This indicates that the vowel of the verb stem changes in various conjugations. In this example, the o is replaced with ue.

Also, the present subjunctive is used when you inform someone that was going to bed is essential, good, or suggested. Thus, some examples of frequent phrases are:

‘I hope that…’ (ehs-PEH-ROH keh) means ‘I hope that…’

‘Deseo Que…’ (deh-seh-oh Keh) is Spanish for ‘I wish that…’

‘Quiero Que…’ (kee-EH-ROH Keh) is Spanish for ‘I desire that…’

Es necesario que… (ehs new-she-SAH-reach Keh) translates as ‘It is required that…’

It’s good that… (as BWEH-noh keh) meaning ‘It’s nice that…’

It is advised that… (as reh-Koh-mean-dah-bleh keh) means ‘It is suggested that…’

It is critical that… (ehs eem-pohr-TAHN-the keh) means ‘It is critical that…’

Dudo que… (DOO-doh keh) means ‘I have my doubts…’

You also don’t need to state the subject pronoun for you, t, Nosotros/as, and Nosotros/as. This is since their corresponding reflexive pronouns already reveal who the subject pronoun is. Thus, they all also share the same reflexive pronoun. However you would clarify who the subject pronoun is in the case of él, Ella, used, and their plural forms.
