demur: [13] Like its French cousin demeurer, demur originally meant ‘stay, linger’. It was not until the 17th century that the current sense, ‘raise objections’, developed, via earlier ‘delay’ and ‘hesitate in uncertainty’. The word comes via Old French demorer and Vulgar Latin *dēmorāre from Latin dēmorārī, a compound verb formed from the intensive prefix dē- and morārī ‘delay’ (source also of English moratorium [19]). => demure, moratorium[demur etymology, demur origin, 英语词源]
