Is the comes of a noble correct grammatically?

"Comes" is not a word in the English language. The correct word is "comes", meaning "to move or approach, especially in a specified way or direction."

It's likely you were thinking of "comes of" which is a phrase that means "results from" or "arises from." For example:

* "What comes of this plan remains to be seen."

* "Her success comes of hard work and dedication."

If you are referring to the status or lineage of a noble you would use the word "noble" or "nobleman/noblewoman". For example:

* "He was born into a noble family."

* "The nobleman had a vast estate."

Please clarify your question if you meant something else, and I can provide a more accurate answer.
