Correct spelling

specially

Correct spelling, explanation: because of the fact, that the adjective special ends with a consonant l, and to create an adverb we need to add suffix -ly, then l will double in specially. This is also why the form specialy is incorrect. When we add suffix -ly to adjectives ending with l, this consonant isn’t dropped, so specially is the correct form.
