- \ \  To deliver something is etymologically to ‘set it free’. The word comes via Old French delivrer from late Latin dēlīberāre, a compound verb formed from the intensive prefix dē- and Latin līberāre ‘set free’, a derivative of the adjective līber ‘free’. Its meaning developed through ‘set free’ to ‘give up, surrender’ and finally ‘hand over to someone else’. (Classical Latin dēlīberāre, source of English deliberate , is an entirely different verb, derived from Latin lībra ‘scales’.)\ \ Cf.⇒ LIBERATE
