Correct spelling

amended

Correct spelling, explanation: amended is the past form of the verb amend, which means to modify something. Amend comes from the Middle English word amenden, first recorded around the 12th century. This old spelling transformed a little, but remained very similar, including just one consonant m. There are also no pronunciation suggestions to spell it differently, therefore ammended is a wrong spelling, and the correct one is amended.

Definition of amended:
verb, the past form of amend; to change something for the better; to rephrase, alter for the better
