"the country between two rivers," from fem. of mesopotamos, from mesos "middle" + potamos "river" (see petition). In 19c. the word was used in the sense of "anything which gives irrational or inexplicable comfort to the hearer," based on the story of the old woman who told her pastor that she "found great support in that comfortable word Mesopotamia" ["Brewer's Dictionary of Phrase & Fable," 1870]. The place was called Mespot (1917) by British soldiers serving there in World War I.
ease: early 13c., from O.Fr. aise "comfort, pleasure," of unknown origin, despite attempts to link it to various L. verbs. The earliest senses in French appear to be 1. "elbow-room" (from an 11th century Hebrew-French glossary) and 2. "opportunity." This led Sophus Bugge to suggest an origin in V.L. asa, a shortened form of L. ansa "handle," which could be used in the figurative sense of "opportunity, occasion," as well as being a possible synonym for "elbow," since L. ansatus "furnished with handles" also was used to mean "having the arms akimbo." OED editors report this theory, and write, "This is not very satisfactory, but it does not appear that any equally plausible alternative has yet been proposed." The verb meaning "to give ease" is from mid-14c.; the sense of "to relax one's efforts" is from 1863. Farmer reports ease in a slang sense of “to content a woman” sexually, with an 1861 date.

O.N. sæll "happy," Goth. sels "good, kindhearted," O.S. salig, M.Du. salich, O.H.G. salig, Ger. selig "blessed, happy, blissful"), from PIE base *sel- "happy" (cf. Gk. hilaros "gay, cheerful," L. solari "to comfort," salvus "whole, safe"). The word's considerable sense development moved from "blessed" to "pious," to "innocent" (1200), to "harmless," to "pitiable" (c.1280), to "weak" (c.1300), to "feeble in mind, lacking in reason, foolish" (1576). Further tendency toward "stunned, dazed as by a blow" (1886) in knocked silly, etc. Silly season in journalism slang is from 1861 (August and September, when newspapers compensate for a lack of hard news by filling up with trivial stories).
