"Mais non, je parle bien anglais."
Here's a breakdown:
* "Mais": means "but"
* "non": means "no"
* "je": means "I"
* "parle": means "speak"
* "bien": means "well" or "good"
* "anglais": means "English"
You can also use "assez bien" instead of "bien" if you want to say "pretty good" or "fairly well" in English.
Here are some other possible translations depending on context:
* "Non, mon anglais est bon.": "No, my English is good." (more formal)
* "Je parle anglais couramment.": "I speak English fluently." (emphasizes fluency)
* "Je suis capable de parler anglais.": "I am able to speak English." (more literal)
The best way to choose the right translation will depend on the specific situation and your desired level of formality.
