Correct spelling


Correct spelling, explanation: the correct form is submitted because here we use the consonant-vowel-consonant rule. It says that we double the last consonant in such a situation if we add a suffix. Therefore t in submit is doubled and the outcome is submitted. Submited is thus a misspelling.

Definition of submitted:
verb, past simple and past participle form of the verb submit, to give out something, usually for approval
Jack, you haven’t submitted your homework yet.
I submitted one of my paintings for the contest at a local gallery.

Incorrect spelling


Incorrect spelling, explanation: this form is incorrect, as we should double the last consonant in submit when adding the suffix (according to consonant-vowel-consonant ending). This way submitted is the correct form, and submited is wrong.
