Especial and especially have a more limited use than special and specially. Special is always used in preference to especial when the sense is one of being out of the ordinary: a special lesson; he has been specially trained. Special is also used when something is referred to as being for a particular purpose: the word was specially underlined for you. Where an idea of pre-eminence or individuality is involved, either especial or special may be used: he is my especial (or special) friend; he is especially (or specially) good at his job. In informal English, however, special is usually preferred in all contexts
