Correct spelling


Correct spelling, explanation: eminently is the correct form as in root Latin eminentem the m isn’t doubled. This points to eminently as the correct form, because there is no phonetic nor orthographic reason to double this letter. Therefore emminently is an incorrect spelling.

Definition of eminently:
adverb, very much
She was so eminently engaged in the help, it was very impressive.
It seems eminently reasonable to meet with them before signing the documents.

Incorrect spelling


Incorrect spelling, explanation: there is no reason to spell eminently with double m, so emminently is a mistake. In the original Latin word eminentem there is also no double consonant m; we don’t have pronunciation reasons for that either. Therefore eminently is the correct spelling.
