Correct spelling, explanation: actually is an adverb from the adjective actual. To create an adverb we add the suffix -ly to an adjective. This way actual becomes actually. L doubles in this case; there is no reason to omit one of l’s. Therefore actualy is the wrong form.

Incorrect spelling, explanation: to create an adverb we add suffix -ly to an adjective. The base adjective, in this case, is actual, thus the adverb is actually – with double l, since the word ends with one l and the suffix begins with another. Therefore actualy is the wrong form, and actually is the correct one.
