Correct spelling

enmity

Correct spelling, explanation: this is the correct form, because of the root word enemy (with suffix -ity added). It was spelled similarly also in its Middle English origin enemite (e was probably skipped later due to pronunciation). Emnity is a mistaken form, probably caused by often sound mn (as in gymnastics, firm). The only correct form, though, is enmity.

Definition of enmity:
noun, a state of hostility

Incorrect spelling

emnity
