'S'endormir' is one of the many reflexive verbs in French. It means 'to fall asleep,' so it's different from the verb 'dormir,' which means 'to sleep.' In this lesson, we will learn how to conjugate 's'endormir' in the present and the past tense.

Conjugating S'endormir in the Present Tense

Conjugating s'endormir (sehn-dorh-meer), to fall asleep, in the present tense is not complicated. Although, it follows both the rules of conjugating verbs ending with -ir and reflexive verbs at the same time.

Let's see the complete table here:

VERB: s'endormir (sehn-dohr-meer) 'to fall asleep'

Subject Pronoun S'endormir Conjugation
Present Tense
Meaning Pronunciation
Je m'endors I fall asleep zuh mehn-dohr
Tu t'endors You (singular, informal) fall asleep tü tehn-dohr
Il/Elle s'endort He/She falls asleep eel/ehl sehn-dohr
Nous nous endormons We fall asleep noo noo zehn-dohr-mohn
Vous vous endormez You (plural/formal) fall asleep voo voo zehn-dohr-may
Ils/Elles s'endorment They fall asleep eel/ehl sen-dohr-muh

As you can see, the beginning of the conjugated verb follows the rule of reflexive verbs, which means you need to use the suitable complement. Don't forget because the root word endormir starts with a vocal letter, the complements me becomes m', te becomes t', and se becomes s'. Meanwhile, the end of the conjugated verb follows the rules of the classic -ir verbs.


  • Je m'endors toujours quand je fais mes devoirs. (I always fall asleep when I do my homework.)
  • Roger s'endort en regardant la télé. (Roger falls asleep while watching TV.)
  • Nous nous endormons parce qu'il fat trop chaud. (We fall asleep because it's too hot.)
  • Vous vous endormez, Monsieur. (You (formal) fall asleep, Sir.)
  • Les enfants s'endorment après la piscine. (The children fall asleep after going to the swimming pool.)

Conjugating S'endormir in the Past Tense (Passé Composé)

Like any other reflexive verbs, to conjugate s'endormir in the passé compose you will need to use the verb être and not avoir. Here's the complete schema:

Subject pronoun + reflexive subject pronoun (me/te/se/nous/vous/se) + être (conjugated in the present tense) + past participle: endormi(e/s/es)

Remember, since you're using the verb être, the past participle must show an agreement when the subject is feminine and/or plural. Which brings us to this complete table:

Don't panic looking at this complex table. Digest each conjugation one by one while keeping in mind that the classical rules apply:

1. Order for conjugating reflexive verbs in the passé compose

2. Rules of agreement in French

To facilitate your learning process, we have put the table in the complete form, which includes the past participle agreements depending on gender and number. For example, see that in the context of formal vous for a male, there's no agreement to the past participle. But the agreement rule applies for the formal vous for a female: endormie.


  • Sarah says: Je me suis endormie car j'étais fatiguée. (I fell asleep because I was tired.)

In this case, you can see that we agree the past participle because Sarah is a feminine subject.
