couter

Couter is the post-1990 spelling-reform form of coûter (to cost) — same meaning, same conjugation, just without the circumflex accent. Both spellings are considered correct, but coûter with the accent remains far more common in print, dictionaries, and everyday writing.

• Ce sac coute cent euros. — This bag costs a hundred euros.
• Combien ça coute ? — How much does it cost?
• Cela m'a couté beaucoup d'efforts. — That cost me a lot of effort.

Because coûter with the circumflex is still what most learners see in textbooks and native writing, encountering couter without it can look like a typo — it isn't; it's simply the 1990 rectified spelling, and both forms are accepted in modern usage.
