Forms
iða f[1][2] ONP records the spellings iða, Iðu, iður, iðunni, íþo and iduna.[3]
Etymology
Ásgeir Blöndal Magnússon derives it from Old Norse ið- (“again, back”), the prefix of iðgjald (“repayment”), and compares Old English edwinde and Middle High German itwǣge, both meaning an eddy.[4] De Vries and Köbler likewise compare the prefix;[5][6] Etymonline names edwielle (“eddy, whirlpool”) as a parallel.[7]
The prefix goes back to Proto-Germanic *eþi, with Old English ed-, Old High German ita- and Gothic 𐌹𐌸 (iþ, “but”), and is compared with Latin et (“and”) and Ancient Greek ἔτι (éti, “yet, further”).[8] Its first sense seems to have been “back, again”, which suits a counter-current.[8][9]
Earliest recorded meaning
ONP's first dated citation, of 1325, is from a legend: Com þv til ar oc mo[n]do fiɴa beiɴ oc ꜹsco saman rekit í eína íþo “Go to the river and you will find bones and ashes driven together into one eddy”;[3] Fritzner cites the same passage from Heilagra manna søgur.[9]
Semantic evolution
Fritzner defines it as a current that turns back and separates from the main stream of a river, and cites it for fishing places: in the Orkney saga men fished in the eddy beside a tidal race, and Norwegian estate books divide the salmon fishing of an iða.[9] In Grettis saga Grettir dives under the waterfall, ok var þat torvelt, því at iða var mikil “and it was hard, because the eddy was strong”.[9] In poetry it is listed among the names for the sea in the þulur.[10][11]
The word continues as Icelandic iða, Faroese íða, Norwegian Nynorsk ide, Swedish ida and Danish ide.[4] De Vries derives English eddy and the Orkney and Shetland words from it;[5] Etymonline is more cautious, calling the Scots ydy of the mid-15th century possibly related.[7] The Icelandic verb iða “to stir, to move to and fro” is recorded only from the 17th century.[4][12]
