Incorrect spelling, explanation: this word is a misspelling, because of the correct form’s Latin origin (immediatus). Immidiately is a mistake probably deriving from pronunciation, however immediately comes from merging adjective mediate with prefix im-, which results in the opposite meaning (thus not direct). This is the reason why immediately is the correct spelling.

Correct spelling, explanation: this word’s origin is Latin, immediatus. Immediate, a core adjective for this adverb, is created from the adjective mediate (a word rarely used, therefore not very well-known), which means not direct. To this adjective, we add the prefix im-, which gives us the opposite meaning. That is why immediately is the correct spelling, and immidiately is incorrect.
