area: [16] Area is a direct borrowing from Latin ārea, which simply meant ‘level piece of open ground, particularly one not built on in a city’. An alternative sense of the Latin word, ‘place where grain is threshed’, has suggested to some etymologists a derivation from the Latin verb ārēre ‘be dry’ (related to ardor and aridus, sources of English ardour and arid).

area (n.)youdaoicibaDictYouDict
1530s, "vacant piece of ground," from Latin area "level ground, open space," used of building sites, playgrounds, threshing floors, etc.; which is of uncertain origin. Perhaps related to arere "to become dry," on notion of a burned clearing or dry, bare space. The generic sense of "amount of surface (whether open or not) contained within any set of limits" is from 1845. Area code in North American telephone systems is attested from 1959.
