'uncage' originates from the prefix 'un-' meaning 'not' and the word 'cage', which comes from Old French 'cage', from Latin 'cavea', meaning 'hollow place, enclosure'.

'cage' changed from the Old French word 'cage' and eventually became the modern English word 'cage'.

Initially, 'cage' meant 'a hollow place or enclosure', but over time it evolved into its current meaning of 'a structure for confining birds or animals'.
