demand: [13] Latin dēmandāre meant ‘entrust something to someone’. It was a compound verb formed from the intensive prefix - and mandāre ‘entrust, commit’ (source of English mandate). As it passed via Old French demander into English, its meaning developed to ‘give someone the responsibility of doing something’, and finally ‘order’.
