Incorrect spelling, explanation: the correct word is a combination of prefix a- and the verb cross (to go through). a-+cross= across, so adding one more c in the middle doesn’t make any sense.

Correct spelling, explanation: as the word across has its origins in a particular verb, any other form is mistaken.
