What It Means

This phrase is about making an educated guess. It is more than just a random thought. You are looking at clues and proposing a reason. Think of it as being a mini-detective. You use logic to explain something that isn't clear yet.

How To Use It

Pair it with the verb pouvoir or devoir. You might say, "Je peux formuler une hypothèse." It often leads into a sentence starting with que. You will likely use the conditional mood here. It makes you sound thoughtful and analytical. It is a great way to introduce an idea without being too bossy.

When To Use It

Use it in a professional meeting to sound sharp. Use it with friends when discussing a juicy mystery. It is perfect for troubleshooting a broken computer or appliance. It works well when you want to be polite. It suggests you aren't 100% sure but have an idea. You will sound like a pro during a brainstorm.

When NOT To Use It

Avoid it for things that are obvious or proven. Don't use it if you are angry and accusing someone. It is too clinical for a heated emotional argument. If you are just guessing a number, use deviner. Keep this phrase for situations requiring a bit of logic. Don't use it while ordering a croissant!
