'uncork' originates from English, specifically the prefix 'un-' meaning 'not' or 'reverse' and the word 'cork', which refers to the stopper used in bottles.

'cork' comes from the Old Spanish word 'corcho', which was derived from the Latin 'cortex', meaning 'bark'.

Initially, it meant 'to remove the bark', but over time it evolved into its current meaning of 'to remove the cork from a bottle'.
