Archives of past columns are organized both by month and alphabetically by topic allowing a quick and easy search by word or phrase. The site also has a hangman-style game, an interactive forum, and links to other language sites. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept.
Different relations link the synonym sets.
