Yesterday, you were introduced to 5 super fast dictionaries that were each given a mark of approval by digg users. Brace yourself as you'll be meeting 5 more super fast dictionaries today that'll blow your socks off.
Dictionary.hm
Founded in 2006, Dictionary.hm aims to be the most used online dictionary on the internet. However, with only 175,000 "non-taboo" (unsure of what this means) definitions in its database, it is one of the smaller dictionaries in this lineup. Nevertheless, Dictionary.hm speed is on par with the rest of the featured dictionaries and comes in a javascript-less version for those of you who won't touch javascript with a 6 foot pole.
OneLook
At 11 years of age, OneLook is the granddaddy of them all. However, Onelook is showing no signs of aging with its blazingly fast ad-supported search results (one ad at the top). If you dislike the banner ad or wish to change other settings, just head over to its customize page. Onelook currently indexes "11,285,460 words in 986 dictionaries", making it the largest dictionary around.
Dict.org
Another oldie, Dict.org could be even older than OneLook. Dict.org has a few hundred thousand words in its database and thanks to its no frills design, answers queries in a flash.
Word Source
"The Social Dictionary" aka Word Source combines user generated content such as ratings, tags and votes with the dull, bland serious nature of a conventional dictionary. The result is a word reference that is fun to use, although I couldn't figure out how many words are actually in its database. Despite its slick interface, which no doubt incurs a bit of overhead, Word Source loads swiftly and doesn't fall far behind the rest.
