Rester conjugation
Rester is a regular ER verb. This means that its endings when conjugated in the present tense are the same as all other regular ER verbs.
Je reste I stay
Tu restes you stay (informal, singular)
Il, elle, on reste he, she, one stays
Nous restons we stay
Vous restez you stay (formal, plural)
Ils, elles restent they stay
Rester: to stay
As stated above, the main usage of rester is “to stay”. For example:
Je suis fatigué et je reste chez moi aujourd’hui.
I’m tired and I’m staying home today.
In the passé composé, a commonly used French past tense used to describe past events which occured at definied times, être (to be) is used as the auxiliary (helping) verb. For example:
Nous sommes restés dans un hôtel de luxe hier soir.
We stayed in a luxury hotel yesterday night.
For this example sentence, a common mistake would be to say “Nous avons restés”. Using avoir as an auxiliary verb would be wrong. Along these lines, you cannot say “j’ai resté” and must say “je suis resté” (I stayed).
To remain
When used as an impersonal expression, il reste translates literally to “it remains” or “left”. The following example sentence could also translate to “We have 15 minutes left”.
Il ne nous reste qu’un quart d’heure.
We only have 15 minutes remaining.
This example sentences uses the negation ne…que, which means “only”.
Here’s another similar example:
Il me reste deux œufs dans le frigo.
I have two eggs left in the fridge.
To remain
One other common usage of rester is “to remain”. For example:
Je suis resté debout pendant tout le concert.
I remained standing during the entire concert.
How do you say “to rest”?
In French, the verb for “to rest” is se reposer. This is a reflexive verb. Thus, je me repose translates to “I rest”.
