Etymology

It is inherited from Middle English aisie (later esi), borrowed from Old French aisié (“comfortable, at ease; well-off”),[2][3][4] the past participle of aisier (“to put at ease”), from aise (“ease”),[2][3][5] the source of ease.[2][6] The American Heritage Dictionary and Merriam-Webster also cite the form aaisié, with the prefix a-, from Latin ad-.[7][8] The Word Origins dictionary traces ease to Latin adjacēns (“lying close by”), the source of adjacent.[9]

Earliest recorded meaning

Able, having the opportunity: probably before 1200.[3] Etymonline gives about 1200 for “at ease, free from discomfort and anxiety”.[2]

Semantic evolution

The sense “not difficult” appears about 1280,[3] or in the late 13th century,[2] perhaps influenced by the noun ease.[3] Old English and early Middle English expressed this idea with ēaþe and īeþe.[2] Of conditions, “comfortable, pleasant”, is early 14th century, and of people, “lenient, calm”, late 14th century.[2] “Easily persuaded” is from the 1610s.[2] The spelling easy appeared in the first half of the 15th century but was established only in the late 17th.[3] Easily is from about 1290,[3] easygoing from 1674 and easy chair from 1707.[3] Be easy is from 1746 and take it easy from 1804, easy does it from 1835, easy money from 1889 and Easy Street from 1890.[2] Easy-peasy is from the 1950s.[9]
