'unlocalized' originates from the prefix 'un-' meaning 'not' and the word 'localized', which comes from 'local', meaning 'pertaining to a particular place'.

'localized' changed from the Latin word 'localis', meaning 'relating to a place', and eventually became the modern English word 'localized'.

Initially, 'localized' meant 'pertaining to a place', but 'unlocalized' evolved to mean 'not restricted to a particular location'.
