Etymology
Etymology Information

'UN' originates from English, specifically as an abbreviation of the phrase 'United Nations' (coined 1945). 'un' (the negative prefix) originates from Old English 'un-' and ultimately from Proto-Germanic '*un-' (a negative prefix).

Historical Evolution

'UN' developed by shortening the modern English phrase 'United Nations' after the organization's founding in 1945. The negative prefix 'un-' was present in Old English as 'un-' (unchanged in form) coming from Proto-Germanic *un- and continuing into Middle and Modern English.

Meaning Changes

'UN' has retained its meaning as the abbreviation for 'United Nations' since its coinage. The prefix 'un-' originally meant 'not' or 'the opposite of' and has largely retained that negative or reversing meaning into modern usage.
