Le bailleur rebouche le trou de cheville.

Bailleur means landlord or lessor.

A few useful notes:

• It is correct French.
• It often sounds a bit formal or legal/administrative.
• In everyday speech, people may more often say propriétaire if the meaning is clear.
• Informally, you might also hear proprio.

So in this sentence, Le bailleur is simply the landlord, but with a slightly more formal tone.

Because reboucher usually means to fill in again, to close up again, or to fill back in.

Compare:

• boucher = to block, plug, stop up, fill
• reboucher = to fill back in, especially a hole that was already there

In a DIY or housing context, reboucher un trou is very common for filling in a hole in a wall after removing a screw, nail, or wall plug.

So rebouche feels very natural here.

Yes, cheville can mean ankle, but it has other meanings too.

In this sentence, it is not about the body. In a building/DIY context, cheville usually means:

• a wall plug
• an anchor
• sometimes a dowel/peg, depending on context

So trou de cheville means the hole left by a wall plug/anchor or a plug hole in the wall.

French words often have several meanings, and the context tells you which one is intended.

Because de + noun often works in French like an English noun modifier.

Here, trou de cheville means something like:

• plug hole
• wall-plug hole
• hole for a wall plug

The second noun often appears without an article when it describes the type or function of the first noun.

Compare:

• une brosse à dents = a toothbrush
• un verre de vin = a glass of wine
• un trou de cheville = a wall-plug hole

So cheville here is part of a noun phrase, not a separate definite thing.

Because they belong to two different noun phrases:

• Le bailleur = the landlord
• le trou de cheville = the wall-plug hole

French uses articles very regularly, so having le twice in one sentence is completely normal.

It is the present tense, third person singular, of reboucher.

Conjugation:

• je rebouche
• tu rebouches
• il/elle/on rebouche
• nous rebouchons
• vous rebouchez
• ils/elles rebouchent

So Le bailleur rebouche le trou de cheville means:

• The landlord fills in the hole
• or The landlord is filling in the hole

The exact English translation depends on context.

Because of the sentence structure.

The pattern is:

• Le bailleur = subject
• rebouche = verb
• le trou de cheville = direct object

So this is a very standard subject + verb + object sentence, just like in English:

• The landlord / fills in / the wall-plug hole

Yes, that is grammatically possible.

But the nuance is slightly different:

• boucher = to plug/block/fill
• reboucher = to fill back in, to restore a surface by closing the hole again

For a hole in a wall, reboucher is often the more natural choice, because the idea is not just blocking it, but repairing it by filling it in again.

A simple approximation is bye-ur, with a French r.

A few points:

• The ai sounds roughly like the y in my.
• The ll here does not sound like a normal English l.
• The ending has a French vowel sound plus the French r.

If you use IPA, it is roughly /bajœʁ/.

A rough guide is:

luh bai-yeur ruh-boosh luh troo duh shuh-vee

Word by word:

• Le = luh
• bailleur ≈ bai-yeur
• rebouche ≈ ruh-boosh
• le trou ≈ luh troo
• de cheville ≈ duh shuh-vee

A few pronunciation tips:

• trou has a clear oo sound
• ch in cheville sounds like sh
• cheville ends like vee, not like English ville
• the French r is not like the English one

Because trou de cheville is the normal noun pattern.

French uses different prepositions in set expressions, and you often just have to learn the combination:

• un verre de vin = a glass of wine
• une machine à laver = a washing machine
• un trou de cheville = a wall-plug hole

So here, de is simply the correct linker for this noun phrase.

The traditional feminine form is bailleresse, but that can sound quite formal or legal.

In modern usage, many speakers prefer:

• la propriétaire
• or another neutral phrasing depending on context

So:

• le bailleur = masculine
• la bailleresse = feminine, but often formal
• la propriétaire = very common in everyday French

Yes, it is grammatical and understandable.

A native speaker would understand it as something like:

• The landlord fills in the wall-plug hole

The only thing to note is that bailleur sounds a bit more formal than casual everyday speech. In a legal, rental, or administrative context, it fits very well.
