Le constat amiable décrit l’infiltration.

French usually needs an article before a singular countable noun when you are talking about a specific thing.

• le = the for a masculine singular noun
• constat is masculine singular

So Le constat amiable means the accident report / the amicable report as a specific document.

Without le, the phrase would sound incomplete in a normal standalone sentence.

Constat amiable is a fixed expression in French, especially in insurance and accident contexts.

It does not just mean a random friendly observation.

It usually refers to a formal report filled in by the parties involved, often after a car accident or in a damage/insurance situation. In broader administrative or insurance contexts, it can refer to an agreed statement of what happened.

So it is best understood as a set phrase, not translated word by word every time.

Not exactly.

In English, amiable usually means pleasant, friendly, nice.

In French, amiable often means something more like:

• amicable
• by mutual agreement
• settled without conflict

So in constat amiable, it suggests that the report is agreed or jointly established by the parties, not that the report itself has a nice personality.

This is a useful false-friend warning for English speakers.

In French, most adjectives come after the noun, unlike English.

So:

• un rapport officiel = an official report
• un constat amiable = an amicable/agreed report

Some adjectives come before the noun, but amiable normally comes after it.

Also, constat amiable is a standard fixed phrase, so you should learn it in that order.

Décrit is the third-person singular present tense form of the verb décrire.

So:

• je décris = I describe
• tu décris = you describe
• il/elle/on décrit = he/she/one describes

In this sentence, the subject is Le constat amiable, which is singular, so the verb is décrit.

No. Décrire is irregular.

It follows a pattern similar to écrire.

A few present-tense forms are:

• je décris
• tu décris
• il/elle décrit
• nous décrivons
• vous décrivez
• ils/elles décrivent

So décrit is something you need to memorize rather than build from a simple regular pattern.

Because French uses elision before a vowel sound.

• la becomes l’
• infiltration begins with i, a vowel

So:

• la infiltration ❌
• l’infiltration ✅

This is very common in French:

• l’école
• l’idée
• l’eau

In French, infiltration often refers to the entry of a substance into a place where it should not be, especially:

• water seepage
• leakage into a building
• moisture penetration

So in this kind of context, l’infiltration often means something like the leak, water intrusion, or water seepage, depending on the exact situation.

Even though the English-looking word is similar, in French it is very common in housing, insurance, and damage reports.

Because décrire is a direct transitive verb: it takes a direct object with no preposition.

So:

• décrire quelque chose = to describe something

That gives:

• Le constat amiable décrit l’infiltration.
• literally: The report describes the infiltration.

You do not say décrire de l’infiltration here.

The sentence follows the normal French pattern:

Subject + Verb + Object

• Le constat amiable = subject
• décrit = verb
• l’infiltration = direct object

So it is structurally very similar to English:

The report describes the leak/infiltration.

• constat is masculine
• infiltration is feminine

That is why the articles are:

• le constat
• l’infiltration (from la infiltration, reduced by elision)

Notice that amiable does not visibly change here. It can be masculine or feminine in the singular with the same written form in many cases, so the phrase stays constat amiable.

A simple pronunciation guide would be:

Le constat amiable décrit l’infiltration
roughly: luh kon-sta ah-mee-ahbl day-kree lehn-feel-tra-syon

A few useful points:

• the final t in constat is normally silent
• décrit sounds like day-kree
• l’infiltration links smoothly after décrit
• French r is the throat r, not the English one

A more careful IPA-style pronunciation is approximately:

[lə kɔ̃sta amjabl dekʁi lɛ̃filtʁasjɔ̃]

No. In normal French pronunciation, the final t in décrit is silent.

So décrit is pronounced basically like day-kree, not day-kreet.

This is very common in French: many final consonants are not pronounced unless there is a special liaison situation, and here there is no pronounced final t.
