Origin: A word inherited from Germanic.
Etymology: Cognate with Old Frisian rōder , rōr rudder (West Frisian roer ), Middle Dutch rōder oar, rudder, (also, rare) rōer rudder (Dutch roer rudder), Middle Low German rōder , rūder , rōr oar, rudder, Old High German ruodar oar, rudder (Middle High German ruoder , German Ruder , in non-specialist use still typically ‘oar’ rather than ‘rudder’) < the Germanic base of row v.1 + a suffix forming instrumental nouns; a morphologically parallel but probably (on semantic grounds) independent formation is shown by Old Icelandic róðr , Norwegian ror , early modern Danish roer , all in sense ‘act of rowing’. The original sense of the word in West Germanic was apparently ‘oar’ (as the derivation from the Germanic base of row v.1 suggests); the earliest rudders were specialized oars, and it was for this reason that the word developed the sense ‘rudder’. Compare also (with different suffix) Old Icelandic ræði oar (chiefly in poetry). Compare further ( < Middle Low German) Norwegian ror rudder, Old Swedish rodher oar, rudder (Swedish roder rudder, formerly also ‘oar’), Danish ror rudder (1561 or earlier as roer). Compare post-classical Latin rotherum (1295 in a British source), Anglo-Norman rother (c1358), both in sense ‘rudder’.In Old English apparently a strong neuter, but probably occasionally a strong masculine (and so perhaps in sense 2c). The use as agent noun (see sense 2c) perhaps partly reflects a separate formation from the same base. A prefixed form gerōðor (neuter plural) oars (compare y- prefix) is also attested. On the change of original ð to d in the γ. forms compare R. Jordan Handb. der mittelenglischen Grammatik (1934) §206. With the shortening of Middle English close ō to ŭ compare the discussion at mother n.1; see also E. J. Dobson Eng. Pronunc. 1500–1700 (ed. 2, 1968) II. §18. In form rather at δ. forms apparently reflecting unrounding of the vowel. The γ. forms are apparently attested earlier as a surname: Willielmus Roddere (1199).
I. A device for steering, and related senses.
1. A paddle or oar used for propelling a vessel. Obsolete.

2.
a. A piece of apparatus specifically designed to steer a boat or ship by means of a blade, which is twisted in the water to manipulate the vessel's direction.Rudders developed from specialized oars hung over the side near the stern of a ship, but in Northern Europe were already of distinctive construction before the Old English period (much earlier in Southern Europe). In early medieval Northern Europe, rudders were typically hung over the side (frequently the starboard side; cf. starboard n.) of the vessel; later they were normally hung centrally along the midships line. A ship's rudder typically consists of the blade and an attachment to control it, either a tiller or (later) a wheel. Large modern vessels can have several rudders.Recorded earliest in steer-rudder n. at steer n.2 Additions.
