'solely-delivered' is a compound word formed from 'solely' and 'delivered'. 'Solely' originates from the Latin word 'solus', meaning 'alone', and 'delivered' comes from the Old French 'delivrer', meaning 'to set free'.

'solely-delivered' combines the modern English words 'solely' and 'delivered' to form a new adjective.

Initially, 'solely' meant 'alone' and 'delivered' meant 'to set free', but together they evolved to mean 'delivered exclusively by a specific means'.
