Word Origin & History

so
O.E. swa, swæ "in this way," from P.Gmc. *swa (cf. O.S., M.Du., O.H.G. so, O.N. sva, Dan. saa, Swed. sa, O.Fris. sa, Du. zo, Ger. so "so," Goth. swa "as"), from PIE reflexive pronomial stem *s(w)o- (cf. Gk. hos "as," O.Latin suad "so," L. se "himself"). So? as a term of dismissal is attested from
1886 (short for is that so?); so what as an exclamation of indifference dates from 1934. So-so "mediocre" is from 1530; so-and-so is from 1596 meaning "something unspecified;" first recorded 1897 as a euphemistic term of abuse.
"The adverb so at the beginning of a sentence ('So I'll pay for it!'), probably of Yiddish origin, occurs frequently in conversation." [M.Pei, "Story of English," 1952]

SOS
1910, from International Morse code letters, chosen arbitrarily as being easy to transmit and difficult to mistake. Not an acronym for "save our ship" or anything else. Won out over alternative suggestion C.Q.D., which is said to mean "come quickly, distress," or "CQ," general call for alerting other
ships that a message follows, and "D" for danger. SOS is the telegraphic distress signal only; the oral equivalent is mayday.

SOS definition


1. Scheme Object System.
2. An infamously losing text editor. Once, back in the 1960s, when a text editor was needed for the PDP-6, a hacker crufted together a quick-and-dirty "stopgap editor" to be used until a better one was written. Unfortunately, the old one was never really discarded when new ones (in particular, TECO) came along. SOS is a descendant ("Son of Stopgap") of that editor, and many PDP-10 users gained the dubious pleasure of its acquaintance. Since then other programs similar in style to SOS have been written, notably the early font editor BILOS /bye'lohs/, the Brother-In-Law Of Stopgap (the alternate expansion "Bastard Issue, Loins of Stopgap" has been proposed).
3. The PDP-10 instruction to decrease a value. Oppose AOS.
