Questions & Answers about Mets la couverture sur le canapé; le chat dort dessus.

Why is there no subject pronoun with Mets? What form is it?

It’s the imperative (a command) of mettre addressed to tu. In French imperatives, the subject pronoun is dropped: (Tu) mets → Mets ! meaning “Put!”

Why does it end with an -s (Mets) if imperatives with tu often drop the -s?

The “drop the -s” rule applies to regular -er verbs (e.g., Parle ! from parler). Mettre is irregular (not an -er verb), and the tu form keeps the -s: tu mets → Mets !

Could it be Met without the -s?

No. Met is the third-person singular present (il/elle/on met). The imperative for tu is Mets !

How do I say it politely or to several people?

Use the vous imperative: Mettez la couverture sur le canapé.
For “let’s put,” use nous: Mettons la couverture sur le canapé.

If I replace with a pronoun, how do I write it?
