Incorrect spelling, explanation: dimention is an incorrect spelling because the original, Latin spelling is dimensionem, so the s remained – the correct form is spelled dimension. The misspelling is probably caused by similar sound -tion, however, Latin origin points to dimension as the correct form.

Correct spelling, explanation: the word dimension comes from Latin dimensionem (measuring), and this is the reason why in English it is also spelled with s, not t. Dimention is a misspelling probably caused by pronunciation (which is similar in words with -tion ending, as in protection). However here, due to the Latin original word, the correct form is dimension.
