Word History

Etymology

Verb

Middle English eilen, eilien "to trouble, afflict, affect (with animate or inanimate agent), be troubled, affected," going back to Old English eglan, eglian "to torment, afflict (with animate or inanimate agent)," going back to Germanic *agljan- (whence also Norwegian egle "to bait, goad, heckle," Danish dialect [Jutland] egle "to goad," [Bornholm] ägla "to scold," Gothic agljan, translating Greek bláptein "to harm, hurt"), of uncertain origin

Note: The Germanic etymon has been compared with an assortment of words inside and outside Germanic, most immediately and unarguably with Old English egle "grievous, painful, loathsome, horrible," Gothic agls, attested only as neuter singular agl, translating Greek aischrós "causing shame, disgraceful," and Gothic aglo, translating Greek thlípsis "tribulation." These have been compared further with Sanskrit agháḥ "evil, bad," Avestan aγa-, and Greek áchnymai, achnýnai "to grieve, lament," áchos "pain, distress." All these have been taken as progeny of an Indo-European base *h₂eg^h-, hypothetically "distress, fear," connected further with Old English ege "fear, terror," Gothic agis, Old Norse agi (see awe entry 1). However, the semantic link between the basic Germanic set (exemplified by Old English eglan and egle) and the other words is tenuous.

Noun

Middle English eil "harm, trouble," perhaps in part going back to an Old English noun *ægl, *ægle, n-stem noun cognate with Gothic aglo "tribulation," derivative of a Germanic adjective agla-, whence Old English egle "grievous, painful"; in part noun derivative of Middle English eilen "to trouble, afflict" and eile "harmful, grievous" (continuing Old English egle) — more at ail entry 1
