Incorrect spelling, explanation: this form is the wrong one because this adverb comes from the adjective definite, spelled with i instead of e. Therefore definitely is the correct spelling, not definetely. The Latin origin is definire, thus also with i.

Correct spelling, explanation: definitely is an adverb from the adjective definite, which comes from the word define and suffix -ite. By adding the suffix last vowel e was omitted. This is why definitely is correct while definetely is definitely a mistake 🙂

Definition of definitely:
adverb, without doubt; in a definite manner
Clair is definitely the prettiest girl in the class.
-Are you going with us to the cinema tonight? –Definitely!
