The Dictionary of Coming to Terms with the Past (Wörterbuch der 'Vergangenheitsbewältigung') examines over 1,000 German words that have Nazi connotations, such as Endlösung (Final Solution) and Selektion, It is featured in a review by der Spiegel. Such loaded words still constitute a minefield for Germans today, as the Archbishop of Cologne discovered last year in a situation analogized to Senator Biden's use of the term "articulate" when referring to Senator Obama.

American Sign Language Flash Video Dictionary is a high quality, free dictionary with a huge number of signs. It includes specialized dictionaries of religious signs, conversational phrases, and ASL for babies. Unfortunately it's not possible to link to specific signs, but if you look inside you'll find words from "Abbreviate" to "Zoom" and phrases such as "I cannot fasten my belt," "has he been neutered?" "I already took a bath," "are you married?" and "I need a better firewall."

Collins Word Exchange "At Collins we pride ourselves on reflecting current language, used by real English speakers across the world." Collins have launched a public forum designed for (amongst other things) discussing 'new' words and the legitamacy of their inclusion in official dictionaries. Chav is probably on its way, but I'm no intellectual snob, but bounce-backability? Even I'd balk at that one.

Dictionary of the Scots Language. The two major historical dictionaries of the Scots language, the Dictionary of the Older Scottish Tongue (DOST) and the Scottish National Dictionary (SND), have been combined into one searchable online edition:

Thus, information on the earliest uses of Scots words can be presented alongside examples of the later development and, in some cases, current usage of the same words. In this way, we hope that the DSL will allow users to appreciate the continuity and historical development of the Scots language. By making the DSL freely available on the Internet, we also aim to widen access to the source dictionaries and to open up these rich lexicographic resources to anyone with an interest in Scots language and culture.
