1 erfiði
n. trouble, toil, labor; höfum erfiði ok ekki erendi, we have the toil, but no result.* * *or erviði (ærfaði, N. G. L. i. 391; ærfuð, id. I. 10), n. [Ulf. arbaiþs = κόπος; A. S. earfoð; O. H. G. arapeit; mod. Germ. arbeit, which shews that mod. Dan. arbeide and Swed. arbete are borrowed from the Germ.; lost in Engl. The etymology of this word is uncertain; the Icel. notion is to derive it from er- priv. and viða = vinna, to work, but it is scarcely right; Grimm, s. v. arbeit, suggests it to be akin to Lat. labor; Max Müller refers it to the root AR, to plough, Science of Language, p. 258, 3rd Ed.; but arfiði (Björn, p. 41) instead of erviði is a fictitious form, and the statement that in old Norse or Icel. it means ploughing rests only on a fancy of old Björn (Dict. l. c.), to which he was probably led by the similarity between Lat. arvum to Germ. and mod. Dan. arbeit, arbeide: in fact the Icel., ancient or modern, conveys no such notion; even in the old heathen poems the word is used exactly in the present sense, which again is the same as in Ulf.]:—toil, labour, and metaph. toil, trouble; in the allit. phrase, e. en eigi eyrendi, toil but no errand, i. e. lost labour, Þkv. 10, 11, Hkv. Hjörv. 5; víl ok e., toil and trouble (of travelling), Hbl. 58, Skálda 163; kváðusk hafa haft mikit e. ok öngu á leið komið, Fms. v. 21, Post. 645. 58, Sks. 235, v. l., N. G. L. l. c.2. metaph. distress, suffering; drýgja e., to ‘dree’ distress, Gm. 35 (heathen poem),—in N. G. L. i. 391 this phrase is used of a priest officiating; hungr, þorsti, e., Hom. 160: in pl., meðr mörgum erfiðum er á hana leggjask, Stj. 51: an old poet (Arnor) calls the heaven the erfiði of the dwarfs, vide dvergr. In the Icel. N. T. erfiði is often used in the very same passages as in Ulf., thus—yðvart e. er eigi ónýtt í Drottni, 1 Cor. xv. 58; í erfiði, í vökum, í föstu, 2 Cor. vi. 5; og hrósum oss eigi tram yfir mælingu í annarlegu erfiði, x. 15; og vort e. yrði til ónýtis, 1 Thess. iii. 5, cp. Ulf. l. c.β. medic. asthma, difficulty in breathing; brjóst-erfiði, heavy breathing.COMPDS: erfiðisdauði, erfiðislaun, erfiðisléttir, erfiðismunir, erfiðisnauð, erfiðissamr, erfiðissemi, erviðisverk. -

Germ. arbeiten; mod. Dan. arbeide is borrowed from Germ.]:—to toil, labour, Edda 149 (pref.), 677. 11; allir þér sem erviðið og þunga eruð hlaðnir, Matth. xi. 28: metaph., e. e-m, to cause one toil and trouble, Bs. i. 726: trans., e. jörðina, to till the earth, Stj. 30: impers., sóttar-far hans erfiðaði, his illness grew worse, Fms. x. 147. In the Icel. N. T. it is sometimes used in the same passages which have arbaidjan in Ulf., e. g. heldr hefi eg miklu meir erfiðað en allir þeir aðrir, 1 Cor. xv. 10; öllum þeim sem styrkja til og erfiða, xvi. 16; að eg hafi til einskis erfiðað hjá yðr, Gal. iv. 11; heldr erfiði og afli með höndum, Ephes. iv. 28; hvar fyrir eg erfiða og stríði, Col. i. 29; þá sem erfiða meðal yðar, 1 Thess. v. 12; því at til þess hins sama erfiðum vér einnig, 1 Tim. iv. 10; in 2 Tim. ii. 6 the Icel. text has ‘sá sem akrinn erjar.’ -
