I have put together a small collection of useful links, resources and other sources of glee related to English words and language. Feel free to contribute your own favourite site, as long as it's primarily non-commercial and of interest to a non-specialist audience.
An invaluable multiple dictionary search engine that enables you to find definitions for all sorts of words. I am very pleased that my own International House of Logorrhea is one of the dictionaries used (though I derive no commercial benefit from OneLook).
A searchable online dictionary with definitions taken from Robert H. Hill's text dictionary of the same name. Useful but rather outdated, and thus of greatest use when looking for obsolete terms from the 19th and early 20th centuries.
Not really a complete dictionary, but a very interesting collection of odd words accompanied by unusual quotes, stories, and etymological connections concerning many of them.
A finely crafted site dedicated to studying Latin and Greek etymological connections with English, but also containing other very interesting linguistic resources. Very useful and user-friendly (paid members only).
A truly unique resource that defies easy description. A mega-meta-thesaurus that reveals the links and relationships between concepts, people and words. Try it!
Each year, Lake Superior State University produces a "List of Words Banished from the Queen's English for Mis-Use, Over-Use or General Uselessness". End word abuse in our time!
A 19th century English phrasebook written by a non-English spaeking Portuguese writer using a Portuguese-French dictionary and a French-English phrasebook. These are the hilarious results.
The homepage for the ultimate newsgroup for those seeking knowledge of the English language. Just remember to spell-check your postings, and, for God's sake, don't ask anything involving "-gry".
