Learn French: L'enfant s'habille et met des vêtements chauds. - The child is getting dressed and putting on warm clothes.

The verb here is s'habiller (to get dressed). It's a reflexive verb, which means the subject is doing the action to itself. The s' is the shortened form of the pronoun se (himself/herself/itself). We drop the 'e' and add an apostrophe because habille starts with a silent 'h'. Without the s', habiller just means "to dress" (like dressing a doll or another person).

The translation says "putting on", but doesn't met come from the verb mettre (to put)?

Yes, exactly! In French, the verb mettre (to put) is also the standard way to say "to put on" when talking about clothing, shoes, or accessories. Here, met is the "he/she/it" form.

Why is chauds (warm) placed after vêtements (clothes)? In English, we say "warm clothes".

In French, most adjectives come after the noun they describe. Only a short list of common adjectives (usually describing beauty, age, numbers, or goodness/size) go before the noun. Since chaud isn't on that special list, it goes after vêtements. Notice it also has an -s at the end to match the plural noun!

Why do we need des before vêtements? The English translation just says "putting on warm clothes".
