Incorrect spelling, explanation: this spelling is incorrect as there are two c’s in success, so there are two in successfully as well. This fact comes from Latin original word, succedere, so sucess and therefore sucessfully are incorrect forms. The correct form of this adverb is successfully.

Correct spelling, explanation: successfully is spelled with double c, because the root word success is spelled this way, and the spelling comes from Latin origin – succedere. Although it may look weird as there are three double-letter situations in this word, successfully is the correct form, not sucessfully.

Definition of successfully:
adverb, in a way that achieves what one has hoped for
