Main rein意思

"Main rein" is not a common phrase in English, and it doesn't have a direct translation. However, if we break down the words, "main" can be associated with "hand" in French, and "rein" can mean "reins" in English, which are the straps used to control a horse.

If we were to interpret this as a literal phrase, it could mean "clean hands" or "pure hands," which might suggest innocence or lack of involvement in something negative. However, without more context, it's challenging to provide an exact meaning. If you're referring to a specific cultural or linguistic context, please provide more details for a more accurate interpretation.
