The 'Knowledge' Connection
Remember that 'connaissance' means 'knowledge'. Think of it as your brain losing its 'knowledge' of the world for a moment.
Don't confuse with 'Conscience'
While 'perdre conscience' exists, 'perdre connaissance' is much more common for a physical faint. 'Conscience' often refers to your moral compass.

What It Means
Perdre connaissance is the standard way to say someone fainted. It literally translates to 'losing knowledge' or 'losing awareness.' When you use this, you are describing a medical or physical event. You are no longer aware of your surroundings. It is a sudden and involuntary blackout.
How To Use It
You use it just like a normal verb. The subject is the person who fainted. You will often see it in the past tense: il a perdu connaissance. It sounds a bit more clinical than s'évanouir. Think of it as 'losing consciousness' versus 'fainting.' It is very common in news reports or medical contexts.
When To Use It
Use it when describing a serious situation. Maybe someone got too hot at a concert. Perhaps a friend saw a needle and hit the floor. It is perfect for calling emergency services. You can also use it figuratively for extreme shock. Imagine hearing such crazy news that you 'almost' lost it.
When NOT To Use It
Do not use this to say you have work to do. That would be avoir du pain sur la planche. Also, do not use it for falling asleep. If you just took a nap, this phrase is too dramatic. People will think you need an ambulance! Avoid it for 'losing your mind' or 'going crazy' too.
Cultural Background
French people value precise language in medical situations. Perdre connaissance comes from the old idea of 'connaissance' as self-awareness. In the 17th century, 'connaissance' was your connection to the world. Losing it meant your soul or mind temporarily left. It reflects a deep philosophical view of the human body.
Common Variations
You will frequently hear s'évanouir as a direct synonym. In slang, people might say tomber dans les pommes. That literally means 'to fall into the apples.' It sounds much funnier and less scary. If someone is just dizzy, they might say avoir un malaise instead.
使い方のコツ
This is a neutral to formal phrase. It is the 'safe' choice for any situation where you need to be clear that someone has blacked out.
The 'Knowledge' Connection
Remember that 'connaissance' means 'knowledge'. Think of it as your brain losing its 'knowledge' of the world for a moment.
Don't confuse with 'Conscience'
While 'perdre conscience' exists, 'perdre connaissance' is much more common for a physical faint. 'Conscience' often refers to your moral compass.
The Apple Alternative
If you want to sound like a local in a casual setting, use 'tomber dans les pommes'. It's the most common idiom for fainting among friends!
