Language constantly evolves to match the evolving society. Words get old and become obsolete, new words come in to enrich our vocabulary. We are witnessing at the moment another interesting linguistic phenomenon: a colloquial meaning of a word is being redefined to its antithesis. Budget always used to mean a plan for expenditure – how much do you have and what you are going to do with it – but it was also used to denote a certain attitude to money: sensible, thrifty, affordable, non-extravagant.
