An idiom is a phrase that cannot be defined literally. Nut is a word, not an idiom. It is a Germanic word.

First of all, it's not a word, it's a phrase. It's French, meaning literally 'pen name'. As an English idiom the meaning is 'pen name'. Also, it's not "real" French either; rather, it was an "evolution" from the French phrase "nom de guerre", which meant "war name". Why the need to bastardize a perfectly good term instead of using a word already perfect for the task ("pseudonym") is well beyond me.

The phrase "as clear as mud" is a figurative expression that means something is confusing, unclear, or not easily understandable. It is meant to highlight the lack of clarity in a situation or explanation, likening it to trying to see through murky water.
