ad. ON. and Icel. víking-r (whence also Norw., Sw., Da. viking, G. wiking), = OE. wícing, OFris. witsing, wising. Cf. also ON. and Icel. víking fem., the practice of marauding or piracy.
The ON. word is commonly regarded as f. vík creek, inlet, bay, + -ingr -ING3, a viking thus being one who came out from, or frequented, inlets of the sea. The name, however, was evidently current in Anglo-Frisian from a date so early as to make its Scandinavian origin doubtful; wícingscea{edh}a is found in Anglo-Saxon glossaries dating from the 8th century, and s{aeacu}-wícingas occurs in the early poem of Exodus, whereas evidence for víkingr in ON. and Icel. is doubtful before the latter part of the 10th cent. It is therefore possible that the word really originated in the Anglo-Frisian area, and was only at a later date accepted by the Scandinavian peoples; in that case it was probably formed from OE. wíc camp, the formation of temporary encampments being a prominent feature of viking raids.
-ing
a suffix forming derivative masculine ns., with the sense of ‘one belonging to’ or ‘of the kind of’, hence ‘one possessed of the quality of’, and also as a patronymic = ‘one descended from, a son of’, and as a diminutive. Found in the same form, or as -ung, in the other Teutonic langs. OE. examples are æ{th}eling ATHELING, cyning KING, lytling little one, child, flýming fugitive, hóring whoremonger; also the patronymics Æ{th}elwulfing son of Æthelwulf, Ecgbrehting, Cerdicing, Wodening, etc. (OE. Chron. anno 855), Adaming, etc. (Lindisf. Gosp. Luke iii. 38), and the gentile names Hoccingas, Iclingas, Centingas (men of Kent), with the Scriptural Gomorringas, Moabitingas, Idumingas, etc. This suffix also formed names of coins, as pending, penning PENNY, scilling SHILLING, and of fractional parts, as feor{th}ing quarter, FARTHING, teo{edh}ung, -ing tenth, TITHING: so ON. {th}ri{edh}jung-r third part, thriding RIDING (of Yorkshire).
Among words of various ages with this suffix are bretheling, bunting, gelding, golding, herring, hilding, sweeting, whiting, wilding. See also the compound suffix -LING (-l + -ing).
