Redefine the dictionary – wordia a new kind of dictionary – a democratic ‘visual dictionary’. A place where anyone with a video, webcam or mobile phone can define the words that matter to them in their life.

Wordia.com – fittingly launched at the house of Dr Samuel Johnson, who compiled the world’s first dictionary 253 years ago – is, effectively (as Birch describes it) “Dictionary.com meet Youtube meets Wikipedia”. It combines a textual dictionary from partner Harper Collins with user-generated videos both from any user and profesionally produced videos featuring celebrities. Users edit, submit and rate definitions on relevance, accuracy or humour. The launch site has 76,000 words and 120,000 definitions, and another 21,000 word thesaurus entries. And the user-definitions are sarting to flood in, like this one.
