Correct spelling


Correct spelling, explanation: the adverb eminently is spelled with one m, because the root word comes from Latin eminentem, which is also spelled with one m. There is no reason to double it, especially that em- is not a prefix, so emminently is incorrect and the correct form is eminently.

Definition of eminently:
adverb, to a high degree
They told us this area is eminently suitable for farming.
Despite his eminently stubborn character, he was quite likeable.

Incorrect spelling


Incorrect spelling, explanation: emminently is a wrong spelling because it shows in Latin original eminentem, that m is not doubled. The correct form of this adverb should be eminently, because of the roots of this word. Therefore eminently is the correct form.
