'uncharted' originates from the prefix 'un-' meaning 'not' and the word 'charted,' which comes from 'chart,' meaning 'a map or plan.'

'uncharted' evolved from the combination of 'un-' and 'charted,' which was used in the 19th century to describe areas not represented on maps.

Initially, it meant 'not represented on a map,' and this meaning has largely remained the same in modern usage.
