B2 especially or specially?

Used in front of an adjective, especially and specially mean the same: especially useful = specially useful. Used in other positions, they differ in meaning. We use especially to indicate that what we are saying applies more to one thing or situation than to others (=sobre todo): Double ovens are a good idea, especially if you are cooking several meals at once. We use specially + Past Participle to say that something is done or made for a particular purpose (=especialmente): Her dress was specially designed for her 40th birthday.
