If the dictionary uses the word ‘want’ to clarify the word ‘need’ and uses the word ‘need’ to clarify the word ‘want’ – we can be sure we’re on to something. Does this mean that wants simply imply needs and that needs imply wants – because the dictionary says so? No. Remember, dictionaries will reflect our own language usage – so if the word ‘want’ has been used over time to indicate a ‘need’ – then it becomes an ‘accepted use of the word’ and is reflected in the dictionary as such. In the same way, the word ‘need’ has been used to describe ‘wants’ – and so it has become ‘normal’. What the dictionary then shows is how we have confused the meanings of the words ‘wants’ and ‘needs’ for ourselves and started using the terms as synonyms.
