Satan (n.)youdaoicibaDictYouDict
proper name of the supreme evil spirit in Christianity, Old English Satan, from Late Latin Satan (in Vulgate in Old Testament only), from Greek Satanas, from Hebrew satan "adversary, one who plots against another," from satan "to show enmity to, oppose, plot against," from root s-t-n "one who opposes, obstructs, or acts as an adversary."

In Septuagint (Greek) usually translated as diabolos "slanderer," literally "one who throws (something) across" the path of another (see devil (n.)), though epiboulos "plotter" is used once.
In biblical sources the Hebrew term the satan describes an adversarial role. It is not the name of a particular character. Although Hebrew storytellers as early as the sixth century B.C.E. occasionally introduced a supernatural character whom they called the satan, what they meant was any one of the angels sent by God for the specific purpose of blocking or obstructing human activity.

society (n.)youdaoicibaDictYouDict
1530s, "companionship, friendly association with others," from Old French societe "company" (12c., Modern French société), from Latin societatem (nominative societas) "fellowship, association, alliance, union, community," from socius "companion" (see social (adj.)).

Meaning "group, club" is from 1540s, originally of associations of persons for some specific purpose. Meaning "people bound by neighborhood and intercourse aware of living together in an ordered community" is from 1630s. Sense of "the more cultivated part of any community" first recorded 1823, hence "fashionable people and their doings." The Society Islands were named 1769 by Cook on his third Pacific voyage in honor of the Royal Society, which financed his travels across the world to observe the transit of Venus.
