Nous rappelons l’électricienne parce qu’une lampe du couloir ne s’allume plus.

Yes, rappeler can mean both to remind and to call back.

In this sentence, Nous rappelons l’électricienne means We’re calling the electrician back or We call the electrician again.

Why not remind here? Because the object is a person you would naturally contact again about a problem. The rest of the sentence—about a lamp not working anymore—makes call back the natural meaning.

L’électricienne is the feminine form of électricien.

• un électricien = a male electrician
• une électricienne = a female electrician

The l’ is used instead of la because électricienne begins with a vowel sound:

• la électricienne → not used
• l’électricienne → correct

So this sentence specifically refers to a female electrician.

Both are possible in French, but they are a little different in tone.

• Nous rappelons = we call back
• On rappelle = also often we call back in everyday spoken French

Nous is a bit more standard or careful.
On is very common in conversation.

So this sentence is perfectly natural, but slightly more formal or written-looking than On rappelle l’électricienne...

This is because of elision.

Parce que becomes parce qu’ before a word beginning with a vowel or silent h:

• parce que la lampe...
• parce qu’une lampe...

French avoids the clash of two vowel sounds, so que loses its e here.

Literally, it means a lamp of the hallway/corridor, but in natural English it usually means one of the hallway lights or a hallway light.

Breakdown:

• une lampe = a lamp / a light
• du couloir = of the hallway / in the hallway

Here du is a contraction of de + le:

• de le couloir → du couloir

So une lampe du couloir means a lamp associated with the hallway, not just any lamp.

Both can make sense, but they are not exactly the same.

• une lampe du couloir = a hallway light / a light belonging to the hallway area
• une lampe dans le couloir = a lamp physically located in the hallway

In many cases, English would translate both simply as a light in the hallway, but French often uses de + room/place to identify what something belongs to.

So une lampe du couloir sounds very natural if you mean one of the lights for that part of the house/building.

S’allume comes from the pronominal verb s’allumer, which means to light up, to switch on, or to come on.

• allumer = to switch something on
  
  • J’allume la lampe. = I switch on the lamp.
• s’allumer = to switch on / light up by itself, or simply to come on
  
  • La lampe s’allume. = The lamp comes on.

So:

• La lampe ne s’allume plus = The lamp doesn’t come on anymore

The s’ is the shortened form of se, used before a vowel:

• se allume → s’allume

Ne ... plus means no longer, not anymore, or not any longer.

So:

• La lampe ne s’allume plus = The lamp doesn’t turn on anymore

This suggests that it used to work before, but now it does not.

Compare:

• ne ... pas = simple negation, not
• ne ... plus = not anymore / no longer

Examples:

• La lampe ne s’allume pas. = The lamp does not turn on.
• La lampe ne s’allume plus. = The lamp no longer turns on.

That second version gives more context: something has changed.

In standard written French, the full negative form is ne ... plus.

So the correct written form is:

• La lampe ne s’allume plus.

In everyday spoken French, many speakers drop ne, especially in casual conversation:

• La lampe s’allume plus.

But that is informal speech. In writing, and especially for learners, you should use ne ... plus.

Because the subject is singular: une lampe.

Even though du couloir adds extra information, the main noun is still lampe, which is singular and feminine.

So the verb is singular too:

• une lampe ... ne s’allume plus

If it were plural, you would have:

• des lampes du couloir ne s’allument plus
  = the hallway lights no longer come on

It is in the present tense, but the French present often covers both simple present and present progressive ideas in English.

So Nous rappelons l’électricienne could mean:

• We call the electrician back
• We are calling the electrician back

English usually chooses between call and are calling depending on context, but French often just uses the present tense.

These are all examples of elision, which is very common in French.

A short vowel is dropped before a following vowel sound:

• la électricienne → l’électricienne
• que une → qu’une
• se allume → s’allume

This makes French sound smoother and avoids awkward vowel collisions.

Yes, very possibly.

In everyday usage, lampe can refer to an actual lamp, but depending on context it can also be understood as a light or light fixture.

So une lampe du couloir ne s’allume plus might mean:

• a hallway lamp no longer turns on
• one of the hallway lights no longer works

The exact English wording depends on the situation, but the French sentence itself is perfectly natural.

Because the idea here is probably about function, not just current state.

• ne s’allume plus = doesn’t switch on anymore / won’t come on anymore
• n’est plus allumée = is no longer on / is no longer lit

Those are different ideas:

• La lampe n’est plus allumée could simply mean someone turned it off.
• La lampe ne s’allume plus means there is a problem: it no longer comes on when you try.

That is why this phrasing fits well with calling the electrician back.
