Here are some possible interpretations and corrections:
* "Au chant, chérie": This translates to "To the song, darling" or "Sing, darling". This is a more grammatically correct and common phrase. It would likely be used in a romantic context, encouraging someone to sing.
* "Au chant, chère": This is similar to the above, but using a slightly more formal address ("chère" instead of "chérie"). It still means "To the song, dear" or "Sing, dear".
* "A chanter, chérie": This means "To sing, darling" and is another possible interpretation of the misspelled phrase. It's used to tell someone to start singing.
* "Un chant, chérie": This means "A song, darling". It could be used to offer a song to someone.
It's important to consider the context of the phrase to figure out the intended meaning.
If you can provide more context (like the situation where you heard this phrase), I might be able to give you a more specific answer.
