Incorrect spelling


Incorrect spelling, explanation: submited is an incorrect form, because t should be doubled (submitted). According to the rule we double the last consonant of a word if the word ends with consonant-vowel-consonant combination. Therefore the correct form is submitted (submit with the suffix -ed).

Correct spelling


Correct spelling, explanation: this is the correct form, because of the rule that says if a word ends with consonant-vowel-consonant combination, then we double the last consonant in case of a suffix. Here, in submitted, we added suffix -ed to the word submit, which gives us double t, hence submitted. Therefore submited is an incorrect spelling.
