Synonymy Lite

How can you go from a word like ‘morbid' to a word like ‘ecstatic'? Or from ‘fastidious' to ‘vigil'? Synonymy is a game of finding the paths between random words through their network of synonyms. By taking the synonym of a word, and then a synonym of that synonym, and so on, you can ultimately arrive at any other word in the English language.
