La manche termine la partie.

Yes — manche is one of those French words with several meanings.

Common meanings include:

• a sleeve
• a handle
• a round / hand / leg in a game or competition

In La manche termine la partie, it means the round (or the hand/leg, depending on context), not the sleeve.

Also note the gender:

• la manche = feminine when it means sleeve or round
• le manche = masculine when it means handle

So the article helps tell you which noun you have.

In French, nouns usually need an article much more often than in English.

So:

• la manche = the round
• la partie = the game / the match

French generally does not drop articles the way English sometimes does. A bare noun like manche termine partie would be ungrammatical.

Also, French often uses the definite article where English might sometimes be less explicit. Here, both nouns are treated as known or identifiable in context: the round and the game.

Termine is the 3rd person singular present tense of terminer.

The subject is la manche, which is singular, so the verb must also be singular:

• je termine
• tu termines
• il/elle/on termine
• nous terminons
• vous terminez
• ils/elles terminent

So in this sentence:

• La manche = subject
• termine = verb
• la partie = direct object

Here it means ends in the sense of brings something to an end.

That is because la manche is causing la partie to be over. So the idea is not that the round is itself finishing; it is that the round ends the game.

A useful distinction:

• La manche se termine. = The round is ending / ends.
• La manche termine la partie. = The round ends the game.

So with a direct object after it, terminer often means to finish/end something.

Because this sentence is using terminer as a transitive verb — a verb that takes a direct object.

Here:

• la manche = the thing doing the action
• la partie = the thing being ended

So:

• La manche termine la partie. = The round ends the game.

But if you say:

• La manche se termine.

then se terminer means to come to an end or to end by itself, with no direct object.

So the difference is:

• terminer quelque chose = to finish/end something
• se terminer = to end / come to an end

Yes, la manche is definitely the subject.

French sentence structure here is straightforward:

• La manche = subject
• termine = verb
• la partie = object

It may feel slightly unusual at first, but English also allows inanimate subjects:

• This round ends the game
• The move ends the match
• The goal decides the game

So grammatically, this is perfectly normal.

Because terminer takes a direct object.

So you say:

• terminer quelque chose = to end/finish something

That means no à, de, or other preposition is needed:

• La manche termine la partie.

Compare that with a different expression:

• mettre fin à quelque chose = to put an end to something

For example:

• La manche met fin à la partie.

Both structures are possible, but they use different grammar:

• terminer + direct object
• mettre fin à + noun

Sometimes yes, but the nuance can change slightly.

Both verbs can relate to finishing or ending, but:

• terminer often sounds like bring to an end / finish
• finir often emphasizes coming to the end or being finished

In many contexts, La manche finit la partie would sound less natural than La manche termine la partie.

More natural alternatives might be:

• La manche termine la partie.
• La manche met fin à la partie.
• Cette manche finit la partie. (possible in some contexts, but more context-dependent)

So while finir is not impossible in all cases, terminer fits this structure more cleanly.

Partie has several related meanings depending on context. It can mean:

• game
• match
• round of play
• session
• sometimes more generally part

In La manche termine la partie, partie most likely means the overall game or match, while manche is one smaller unit inside it, such as a round or hand.

So the relationship is something like:

• manche = one round/leg/hand
• partie = the whole game/match

Yes, it is grammatical and understandable. It sounds like something you might see in a game-related context, especially where one round determines that the whole game is over.

Depending on the exact situation, a native speaker might also say:

• Cette manche termine la partie.
• La manche met fin à la partie.
• Cette manche décide la partie.

So your sentence is fine, but context matters for which wording sounds most idiomatic.

A simple pronunciation guide is:

la mahnsh tair-meen la par-tee

More approximately in IPA: /la mɑ̃ʃ tɛʁ.min la paʁ.ti/

A few helpful points:

• manche: the an is nasal, so it is not pronounced like English man
• r in termine and partie is the French r
• partie ends with -tie sounding like tee

So the rhythm is: La manche | termine | la partie
