Le coéquipier veut remporter la revanche.

French usually needs an article before a singular countable noun. So le coéquipier means the teammate.

If you removed le, the sentence would sound incomplete in normal French.

• le coéquipier = the teammate
• un coéquipier = a teammate

Here, le tells you we are talking about a specific teammate, or about the teammate in a general/contextual sense.

Because elision to l’ only happens before a vowel sound or a mute h.

Even though coéquipier contains vowels, it begins with the consonant sound k:

• coéquipier → starts with c pronounced k

So you keep le:

• le coéquipier
• not l’coéquipier

Yes, coéquipier is the masculine singular form.

The feminine singular form is coéquipière.

• le coéquipier = the male teammate
• la coéquipière = the female teammate

In your sentence, le shows that the noun is masculine singular.

Veut is the third-person singular form of vouloir (to want).

Since le coéquipier means he / the teammate, you need the il/elle/on form:

• je veux = I want
• tu veux = you want
• il/elle/on veut = he/she/one wants
• nous voulons = we want
• vous voulez = you want
• ils/elles veulent = they want

So:

• Le coéquipier veut... = The teammate wants...

After vouloir, the next verb normally stays in the infinitive.

So French uses:

• veut remporter

This works like English wants to win, but French does not insert a separate word equivalent to to here.

A useful pattern is:

• subject + vouloir + infinitive

Examples:

• Je veux partir. = I want to leave.
• Elle veut essayer. = She wants to try.
• Le coéquipier veut remporter la revanche.

Both remporter and gagner can mean to win, but remporter often sounds a bit more formal or more specifically tied to victory, a match, a title, a trophy, or a contest.

So:

• gagner = general everyday to win
• remporter = to win/carry off a victory, match, title, etc.

In sports or competitive contexts, remporter is very natural.

For example:

• remporter un match
• remporter une victoire
• remporter le championnat

So veut remporter la revanche sounds quite natural in a competitive context.

Revanche can be tricky because its meaning depends on context.

Common ideas include:

• revenge
• a comeback win
• a rematch
• getting one’s own back after a previous loss

In sports, la revanche often suggests the rematch or the chance to avenge an earlier defeat.

So in this sentence, it likely refers to a specific competitive return match or an opportunity to reverse an earlier result.

Also note that revanche is feminine, which is why the sentence uses la.

French uses articles more often than English does.

So where English might sometimes say something like win revenge or win the rematch depending on the wording, French normally wants the noun with an article:

• la revanche

The article shows that this is a specific revenge/rematch already understood in the situation.

Yes. The sentence follows a very common French pattern:

• subject + conjugated verb + infinitive + object

So here you get:

• Le coéquipier = subject
• veut = conjugated verb
• remporter = infinitive
• la revanche = object

That makes the structure very close to English:

• The teammate wants to win the rematch.

A careful pronunciation of coéquipier is:

• /ko.e.ki.pje/

A careful pronunciation of the whole sentence is:

• /lə ko.e.ki.pje vø ʁɑ̃.pɔʁ.te la ʁə.vɑ̃ʃ/

A few helpful notes:

• In coéquipier, the o and é are pronounced in separate syllables.
• veut has the French eu sound, which does not exist exactly in English.
• revanche ends with the -anche sound pronounced roughly like ahnsh, but with a French nasal vowel.
