Le délai de restitution suit la remise des clés.

No. Here suit is the third-person singular form of the verb suivre, which means to follow.

So:

• Le délai ... suit ... = The period/time limit ... follows ...
• In natural English, this often means comes after

It is not related to the English verb to suit.

Délai usually means a time limit, period allowed, or deadline-related period depending on context.

In this sentence, le délai de restitution is the period within which something must be returned or handed back.

So délai is not just any general time; it usually suggests an allowed or required period.

Restitution means returning something, handing it back, or restoration to its owner/proper place, depending on context.

In administrative, legal, or rental contexts, restitution often means:

• returning keys
• returning a deposit-related item
• handing back a property or object

So here, restitution most likely means the return/handover back of something, depending on the broader context.

Because restitution is a feminine singular noun, and after de there is no article here.

So:

• le délai de restitution = the return period / the period for restitution

This is a very common French structure:

• le délai de paiement = payment deadline
• la date de départ = departure date
• le certificat de naissance = birth certificate

It works like noun + de + noun, where the second noun specifies the first.

Remise means handover, delivery, or giving over, depending on context.

So:

• la remise des clés = the handing over of the keys

This phrase breaks down like this:

• la remise = the handover
• des clés = of the keys

This is a very common pattern in French:

• la remise du dossier = handing over the file
• la remise des documents = handing over the documents

Because after the noun remise, French often uses de to link to what is being handed over:

• la remise de les clés would contract to la remise des clés

So des here is not really the indefinite article some. It is the contraction of:

• de + les = des

That is why:

• la remise des clés = the handover of the keys

Compare:

• le retour des livres = the return of the books
• la fermeture des portes = the closing of the doors

French uses articles more often than English does.

Here:

• Le délai = the period/time limit
• la remise = the handover
• des clés = of the keys

In English, we might sometimes omit an article in a more abstract phrase, but French usually keeps one.

This is very normal French style, especially in formal or administrative language.

Yes, it sounds fairly formal and somewhat administrative.

Words like:

• délai
• restitution
• remise

are common in official, legal, rental, or procedural contexts.

In everyday speech, a French speaker might choose something simpler depending on the situation, but this sentence is perfectly natural in formal writing.

Yes, depending on the nuance.

For example:

• Le délai de restitution commence après la remise des clés.
  = The return period begins after the handover of the keys.

• Le délai de restitution court à compter de la remise des clés.
  = The return period runs from the handover of the keys.

• Le délai de restitution intervient après la remise des clés.
  = The return period takes place after the handover of the keys.

The original suit is correct, but it is a bit formal and concise.

The structure is:

• Le délai de restitution = subject
• suit = verb
• la remise des clés = object/complement

So it is a normal French word order:

subject + verb + object

Even though the nouns are abstract and formal, the grammar is straightforward.

A few common mistakes are:

1. Reading suit like the English verb to suit

   • But here it comes from suivre

2. Thinking des clés means some keys

   • Here it means of the keys, from de + les

3. Not recognizing remise

   • In many contexts it means handover or delivery, not just discount

4. Translating too literally

   • A more natural English rendering may be The return period begins after the handover of the keys rather than a word-for-word version

Clés is plural because it means keys.

• singular: la clé = the key
• plural: les clés = the keys

Pronunciation:

• clé and clés are pronounced the same
• roughly like clay in English, but with a pure French vowel

As often happens in French, the final s of the plural is usually silent.

Both clé and clef exist, and both are correct.

Today, clé is very common and often preferred in modern usage.
Clef is also standard and still widely understood.

So you may see:

• la remise des clés
• la remise des clefs

They mean the same thing.
