deserve: [13] Latin dēservīre meant ‘serve well or enthusiastically’ (it was a compound verb formed from the intensive prefix dē- and servīre ‘serve’). Hence in late Latin it came to mean ‘become entitled to because of meritorious service’, a sense which passed via Old French deservir into English. The more general modern English ‘be worthy of’ developed in the 15th century.
