L’expert vient constater le dommage.

Because expert begins with a vowel sound, French normally contracts le to l’ before it.

So:

• le expert → not used
• l’expert → correct

This is the same pattern as:

• l’homme
• l’hôtel
• l’idée

Here, expert is masculine singular, so the full article would be le, but it becomes l’ before the vowel.

In this kind of sentence, l’expert often means a professional sent to assess something, especially in an insurance or legal context.

So depending on context, it may be closer to:

• the assessor
• the adjuster
• the surveyor
• the expert appraiser

A native English speaker might think of expert only as someone very knowledgeable, but in French it can also be a formal role: someone who comes to inspect and officially evaluate a situation.

This is a very important difference.

• vient constater = comes to inspect / is coming to inspect
• vient de constater = has just observed / has just found

So:

• L’expert vient constater le dommage.
  = The expert is coming in order to inspect the damage.

• L’expert vient de constater le dommage.
  = The expert has just inspected / has just noted the damage.

The little word de completely changes the meaning.

French often uses one verb directly followed by an infinitive, where English uses to + verb.

Here:

• vient constater
• literally: comes inspect
• natural English: comes to inspect

So the idea of to is understood in French without needing a separate word here.

This is common with verbs of movement:

• Je viens voir. = I’m coming to see.
• Il sort acheter du pain. = He goes out to buy bread.
• Elle monte chercher ses clés. = She goes upstairs to get her keys.

Constater does not mean simply to see in an ordinary casual way. It usually means something more like:

• to observe
• to note
• to establish
• to verify
• to assess officially

In this sentence, constater le dommage suggests a formal inspection or professional assessment of the damage.

That is why constater is a good fit with l’expert. It sounds official and procedural, not casual.

Yes, it is the same word, but the meaning is different.

dommage can mean:

1. damage / harm
   
   • constater le dommage
2. a pity / a shame
   
   • C’est dommage.

So the meaning depends on context.

In your sentence, because of constater and the insurance-like context, dommage clearly means damage.

French often uses the singular to refer to damage as a general or collective idea.

So le dommage can mean:

• the damage
• the harm that has been done

In other contexts, you may also see:

• les dommages = damages / harm / losses
• les dégâts = physical damage, especially visible damage

In many practical situations, les dégâts is very common for physical damage to property.

But le dommage is perfectly correct, especially in formal, legal, or insurance-related language.

Yes. In many contexts, the French present tense can correspond to several English forms, including:

• comes
• is coming
• sometimes even will come, depending on context

So L’expert vient constater le dommage might naturally be translated as:

• The expert comes to inspect the damage.
• The expert is coming to inspect the damage.

In real English, is coming is often more natural if this is about a scheduled visit that is about to happen.

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

So French prefers:

• constater le dommage

rather than leaving the noun bare.

The definite article le suggests that the damage is already known or identifiable in the situation: the damage in question, the damage that has been reported, the damage on the property, and so on.

Yes, it sounds fairly formal or administrative.

That comes from words like:

• expert
• constater
• dommage

A more everyday sentence might use different wording, depending on context. For example, people might say something closer to:

• L’expert vient voir les dégâts.

This is less formal and more conversational, while L’expert vient constater le dommage sounds more official, like something from insurance paperwork or a formal report.
