In French, the phrase ‘so so’ can be translated as «comme ci, comme ça».
This expression is used to convey a sense of mediocrity or indifference, similar to how we use ‘so so’ in English. It indicates that something is neither particularly good nor particularly bad; it’s just average. For example, if someone asks how you’re feeling and you reply ‘comme ci, comme ça’, you’re telling them you’re not great, but you’re not terrible either.
To use it in a sentence: «Comment ça va?» (How are you?) could be answered with «Comme ci, comme ça.» (So so.)
