Origin & History of “rate”

English has two words rate. The commoner, ‘relative quantity’ (15th c.), comes via Old French rate from medieval Latin rata ‘calculated, fixed’, as used in the expression pro rata parte ‘according to a fixed part, proportionally’. this was the feminine form of ratus, the past participle of rērī ‘think, calculate’, from which English also gets ratio, ration, reason, etc. The other rate, ‘scold’ (14th c.), is now seldom encountered except in its derivative berate (16th c.). It is not certain where it comes from, although a possible source is Old French reter ‘accuse, blame’, which comes from Latin reputāre (ancestor of English reputation).
