To notice something

Bonjour Blaise,

Both constater and remarquer mean "to notice" or "to observe," but they have distinct nuances:

Constater

 

More formal and objective, it means to establish or verify a fact through observation, often implying a neutral, official, or definitive observation. It is common in formal, professional, or administrative contexts

Translation: "to note," "to establish," "to ascertain"

Remarquer

More casual and subjective, means to notice something that catches your attention, implying something stood out or was worth mentioning. It is common in everyday conversation

Translation: "to notice," "to remark," "to observe"

Hope this helps!
