The credit crunch has become such a major issue for households that it has entered into the official lexicon.
The latest edition of the Concise Oxford English Dictionary (OED) carries a definition of crunch as "a severe shortage of money or credit".
Other new entries include "non-doms" and "sub-prime" from the business world, plus "custard creams" and the decorative headpiece, a "fascinator".
