Etymology

It is inherited from Middle English ore, also or and oor,[2][3][4] inherited from Old English ār,[5][2][6][7][4] from Proto-Germanic *airō,[8][9][6][2] the source also of Old Norse ár, Swedish åra and Danish åre.[6][2][10] Finnish airo and Latvian airis are probably borrowings from Germanic.[11][10] The OED, in its revised entry, thinks that the word is probably from early Scandinavian, since the continental West Germanic languages have no cognates.[11] Weekley likewise called it a Viking word.[12] Its further origin is unclear: Orel calls it unknown and Klein uncertain.[9][3] Kroonen finds a link with the verb row attractive but formally impossible,[8] and Etymonline finds it apparently unrelated to the root of Latin rēmus (“oar”) and of row.[6] Ayto thinks a link with the Latin noun possible.[10] A more widely proposed comparison is Ancient Greek οἴαξ (oíāx, “tiller, helm”),[11][9][2][13] though the OED notes phonological difficulties;[11] Kroonen thinks a comparison with an Indo-European s-stem more convincing, and reconstructs Proto-Indo-European *h₃eiH-r-eh₂-, with Lithuanian íena as a possible relative.[8] Johnson guessed at the same root as the verb ear, to plough, and Latin arō.[14]

Earliest recorded meaning

A long pole with a flat blade, used to move a boat: in the Anglo-Saxon Chronicle, in a passage on ships with sixty oars, which Barnhart and Bosworth–Toller date 897 and the OED cites under the annal for 896.[2][15][11]

Semantic evolution

The modern spelling began to appear in the 1580s.[2] To put one's oar in, to meddle, is recorded from 1542,[11] and Cotgrave has the fuller "one that hath an oare in everie mans boat".[12] The word was also used of oar-like limbs of animals in the 1580s,[6] and of anything that propels like an oar about 1595.[11] The plural came to mean a rowing boat, as in a pair of oars (1598), now an archaic use, and the singular a rower (1648).[11] The oar stood for forced rowing in the galleys from 1682,[11] and brewers gave the name to a pole for stirring mash from 1735.[11] To rest on one's oars, or lie on one's oars, to stop working for a while, is recorded from 1726,[11] and Weekley calls rest the modern version.[12] The verb is recorded in isolation from about 1410,[2] and then in Shakespeare's Tempest.[2][11] In Northumberland oars was a cant term for the arms.[16] In North American colloquial use, not having both oars in the water has meant being mentally unsound since 1980.[11]
