La victime reprend connaissance.

Reprend is the 3rd person singular present form of reprendre.

• reprendre literally often means to take again, to resume, or to recover
• in this sentence, it is part of the fixed expression reprendre connaissance, which means to regain consciousness

So:

• reprendre = infinitive
• reprend = he/she/it regains / is regaining

Because the subject is la victime (the victim), French uses reprend.

Yes, it is the present indicative.

French uses the simple present more broadly than English does, so this sentence could be translated in different natural ways depending on context:

• The victim regains consciousness.
• The victim is regaining consciousness.
• The victim comes to.

So even though French only has reprend here, English may use either a simple form or a progressive form.

Victime is a grammatically feminine noun in French, so it takes la.

That does not necessarily mean the person is female. A male victim is still:

• la victime

This is a good example of how grammatical gender and real-life sex/gender are not always the same thing in French.

Yes, connaissance often means things like:

• knowledge
• familiarity
• acquaintance

But in the fixed expression perdre connaissance / reprendre connaissance, it means consciousness.

So this is one of those cases where you should learn the whole expression as a unit:

• perdre connaissance = to lose consciousness
• reprendre connaissance = to regain consciousness

This is a very common confusion.

• connaissance usually relates to knowledge or, in this fixed phrase, consciousness
• conscience usually means conscience or awareness

Examples:

• perdre connaissance = to pass out / lose consciousness
• reprendre connaissance = to come round / regain consciousness
• prendre conscience de quelque chose = to become aware of something

So in this sentence, connaissance is the correct word.

Because reprendre connaissance is a set expression in French.

French often uses verb + noun expressions without an article, especially in idiomatic phrases. Here, the natural phrase is simply:

• reprendre connaissance

Not:

• reprendre la connaissance

So this is best learned as one chunk rather than translated word by word.

Because the normal French expression is simply:

• reprendre connaissance

It is not reflexive.

French does have se reprendre, but that means something different, such as:

• to pull oneself together
• to recover one’s composure
• to correct oneself

So for regaining consciousness, the correct form is:

• La victime reprend connaissance.

A careful pronunciation is:

/la vik.tim ʁə.pʁɑ̃ kɔ.nɛ.sɑ̃s/

A few useful points:

• la = short la
• victime = veek-teem, with the final e silent
• reprend = the final d is silent
• connaissance = ends with an s sound because of -ce
• -prend and the end of connaissance both contain nasal vowel sounds

So the final written consonants are not always pronounced the way an English speaker might expect.
