I am developing an app for windows phone (using Javascript ) which requires displaying meaning of a word typed by the user, so what are the ways through which I can get the meaning of the words online, Just the meaning is enough (i mean no need for etymology, etc..).
A file can be used, but it takes too much memory space so what are the alternate approaches ?
