En plus, l’expert examine la canalisation.

It works as a connector meaning in addition, also, or what’s more. It links this sentence to something said before.

In everyday French, en plus is very common. In more formal writing, you might also see de plus.

Because French uses elision before a vowel sound. The article le becomes l’ when the next word starts with a vowel or a silent h.

So:

• le + expert becomes l’expert

This is the same pattern as:

• l’homme
• l’idée
• l’école

Yes. In this sentence, expert is masculine singular.

If you want the feminine form, you usually say experte:

• l’expert = the male expert
• l’experte = the female expert

Because both words begin with a vowel sound, the article is still l’ in both cases.

Examine is the present indicative form of the verb examiner, matching a third-person singular subject such as l’expert.

Conjugation of examiner in the present:

• j’examine
• tu examines
• il / elle / on examine
• nous examinons
• vous examinez
• ils / elles examinent

So l’expert examine means the expert examines / is examining, depending on context.

Usually, yes. Examiner often means to examine, inspect, or look at carefully.

In this sentence, it suggests that the expert is checking or inspecting the pipe or line carefully. Depending on context, English might translate it as examines, inspects, or checks.

Because canalisation is a feminine singular noun, so the definite article is la.

In French, nouns have grammatical gender, and you have to learn the noun together with its article:

• la canalisation

That helps you remember both the gender and the correct article.

Because la canalisation is definite. It refers to a specific pipe, drain, line, or conduit that is known from the context.

If you wanted a pipe/line, you would normally say:

• une canalisation

French also uses definite articles a bit more often than English, so sometimes the appears where English might choose a different wording.

Not really in everyday use. In French, canalisation often means something concrete like a pipe, pipeline, drain, water line, or conduit.

The English word canalization is much less common in normal conversation and often sounds more technical or abstract. So this is a word where the most natural English translation depends heavily on context.

Yes. The sentence has a very standard structure:

• En plus = connector
• l’expert = subject
• examine = verb
• la canalisation = direct object

So the core pattern is basically subject + verb + object, just with an extra expression at the beginning.

When En plus is used as a sentence opener like this, the comma is very natural because it separates the connector from the main sentence.

So:

• En plus, l’expert examine la canalisation.

In informal writing, people sometimes leave out such commas, but here the comma is a good choice.

A simple approximate pronunciation is:

• En plus → ahn plu
• l’expert → lek-sper
• examine → eg-za-meen
• la canalisation → la ka-na-lee-za-syon

A few useful notes:

• en has a nasal vowel, so it is not pronounced like a normal English n sound.
• In expert, the final t is normally silent.
• The x in expert sounds like ks.
• The ending -tion in canalisation sounds like syon.
