'uncomposed' originates from the prefix 'un-' meaning 'not' and the word 'compose' from Latin 'componere', where 'com-' meant 'together' and 'ponere' meant 'to place'.

'compose' changed from the Latin word 'componere' and eventually became the modern English word 'compose'.

Initially, 'compose' meant 'to place together', but over time it evolved into its current meaning of 'to create or arrange'.
