Englishplus/grammar extract : There is little or no difference between the words especially and specially. In the sense of "particular" or "particularly," the words mean pretty much the same thing. Often they can be used synonymously. However, if you want to stress the exceptional or noteworthy quality, then especial or especially is a better choice. If you want to stress the distinctive purpose of something, then special or specially is the word you are looking for. Example: This program has specially designed macros for word processors. (A distinctive purpose) Example: He did especially well in All-Star Game. (A noteworthy performance)
