英文詞源

rudder: rudder: [OE] Rudder comes from the same source as English row ‘use oars’ – prehistoric Germanic *rō- ‘steer’. Indeed it originally denoted an ‘oar used for steering’; the modern application to a fixed steering surface did not emerge until the 14th century. Its west Germanic ancestor *rōthra- also produced German ruder and Dutch roer.
=> row
rudder (n.): mid-15c. alteration of Middle English rother, from Old English roeor "paddle, oar," from Proto-Germanic *rothru- (cognates: Old Frisian roeer, Middle Low German roder, Middle Dutch roeder, Dutch roer, Old High German ruodar, German Ruder "oar"), from *ro- "steer" (see row (v.)) + suffix -tra, used to form neutral names of tools.

Meaning "broad, flat piece of wood attached to the stern of a boat and guided by a tiller for use in steering" is from c. 1300. For shift of -th- to -d- compare burden (n.1), murder (n.); simultaneous but opposite to the movement that turned -d- to -th- in father (n.), etc.
