Could you tell me what nation the word Chante meaning heart is from as well correct pronunciation?

You're likely thinking of the word "chante" in French, which means "to sing", not "heart".

There is no common word in any language that directly translates to "heart" as "chante".

If you're looking for a word for "heart" in another language, please let me know the language you're interested in, and I can provide the correct word and pronunciation.
