How to Spell merci beaucoup with punctuation marks?

The phrase "merci beaucoup" is spelled with the letters m-e-r-c-i followed by a space and then b-e-a-u-c-o-u-p. Punctuation marks are not typically used in this phrase as it is a simple expression of gratitude in French. However, if you were to add punctuation marks, you could consider using a comma after "merci" to separate it from "beaucoup."
