strumpet (n.)

"harlot; bold, lascivious woman," early 14c., of uncertain origin. One theory connects it with Latin stuprata, fem. past participle of stuprare "have illicit sexual relations with," or Late Latin strupum "dishonor, violation." But evidence for this is wanting and others suggest Middle Dutch strompe "a stocking," or strompen "to stride, to stalk" (as a prostitute might a customer). The major sources don't seem to give much preference to any of these. Weekley notes "Gregory's Chronicle (c. 1450) has streppett in same sense." In 18c.-early 19c., often abbreviated as strum and also used as a verb, which led to some odd dictionary entries:

TO STRUM: to have carnal knowledge of a woman, also to play badly on the harpsichord or any other stringed instrument. [Capt. Francis Grose, "A Classical Dictionary of the Vulgar Tongue," 1785]

book-burning (n.)

"mass destruction by fire of published material deemed obscene, corrupting, etc.," 1850, from book (n.) + verbal noun from burn (v.). As an adjective, it is attested from 1726 (in John Toland, who was a victim of it).

What an irreparable destruction of History, what a deplorable extinction of arts and inventions, what an unspeakable detriment to Learning, what a dishonor upon human understanding, has the cowardly proceeding of the ignorant or rather of the interested against unarm'd monuments at all times occasion'd! And yet this Book-burning and Letter-murdring humor, tho far from being commanded by Christ, has prevail'd in Christianity from the beginning .... [John Toland, "The History of the Druids," 1726]

defile (v.)

c. 1400, "to desecrate, profane;" mid-15c., "to make foul or dirty," also "to rape, deflower," alteration of earlier defoulen, from Old French defouler "trample down, violate," also "ill-treat, dishonor," from de- "down" (see de-) + foler "to tread," from Latin fullo "person who cleans and thickens cloth by stamping on it" (see foil (v.1)).

The alteration (or re-formation) in English is from influence of Middle English filen (v.) "to render foul; make unclean or impure," literal and figurative, from Old English fylen (trans.), related to Old English fulian (intrans.) "to become foul, rot," from the source of foul (adj.). Compare befoul, which also had a parallel form befilen. Related: Defiled; defiling.

ruin (n.)

late Old English, "act of giving way and falling down" (a sense now obsolete), from Latin ruina "a collapse, a rushing down, a tumbling down" (source also of Old French ruine "a collapse," Spanish ruina, Italian rovina), which is a derivative of ruere "to rush, fall violently, collapse" (from PIE *reue- (2) "to smash, knock down, tear out, dig up;" see rough (adj.)).

The sense of "descent from a state of prosperity, degradation, downfall or decay of a person or society" is from late 14c. The general meaning "violent or complete destruction" (of anything), "a profound change so as to unfit a thing for use" (of one's principles, one's shirt, etc.) is by 1670s; the sense of "that which causes destruction or downfall" is from early 15c. The meaning "dishonor," of a woman, is from 1620s. Ruins "remains of a decayed building or town" is from mid-15c.; the same sense was in the Latin plural noun.

smear (v.)

Middle English smeren, from Old English smerian, smierwan, smyrian "anoint or rub with ointment, oil, etc.," from Proto-Germanic *smerwjan "to spread grease on" (source also of Old Norse smyrja "to anoint, rub with ointment," Danish smøre, Swedish smörja, Dutch smeren, Old High German smirwen "apply salve, smear," German schmieren "to smear;" Old Norse smör "butter"), from PIE *smeru- "grease" (source also of Greek myron "unguent, balsam," Old Irish smi(u)r "marrow," Old English smeoru "fat, grease, ointment, tallow, lard, suet," Lithuanian smarsas "fat").

Originally especially "to anoint," but also in Old English "overspread too thickly with something thick or sticky." In modern use also of bad painting or makeup. The figurative sense of "assault a public reputation" is by 1835; especially "dishonor or besmirch with unsubstantiated charges." Related: Smeared; smearing. Smear-word, one used regardless of its literal meaning but invested with invective, is from 1938.

masturbation (n.)
Origin and meaning of masturbation

"deliberate erotic self-stimulation," 1711 (earlier as mastupration, 1620s), from French masturbation and directly from Modern Latin masturbationem (nominative masturbatio), noun of action from past-participle stem of Latin masturbari "to masturbate."

The long-standing speculation is that this Latin word is altered (probably by influence of turbare "to disturb, confuse") from *manstuprare, from manu, ablative of manus "hand" (see manual) + stuprare "defile" (oneself), from stuprum "defilement, dishonor," related to stupere "to be stunned, stupefied" (see stupid). Hence the earliest form of the word in English. But perhaps the first element represents an unattested *mazdo- "penis" [OED]. An earlier technical word for this was onanism. Related: Masturbational.

Farmer and Henley ["Slang and Its Analogues," 1898] lists among the slang terms for "to masturbate" or "masturbation" frig (which they trace to Latin fricare "to rub") to bob; to box the Jesuit; to chuff, to chuffer; to claw; to digitate (of women); to fight one's turkey (Texan); to handle; to indorse; to milk; to mount a corporal and four; to dash one's doodle; and they note that it was "sometimes known as KEEPING DOWN THE CENSUS."

slander (n.)

late 13c., sclaundre, "state of impaired reputation; disgrace or dishonor;" c. 1300, "a false tale or report spread maliciously; the fabrication and dissemination of false tales to discredit someone," from Anglo-French esclaundre, Old French esclandre "scandalous statement," alteration ("with interloping l" [Century Dictionary]) of escandle, escandre "scandal," from Latin scandalum "cause of offense, stumbling block, temptation" (see scandal).

It is attested from mid-14c. as "action or situation that brings shame or disgrace;" late 14c. as "a bad situation, evil action" and in reference to a person causing such a state of affairs.

The injury [slander] consists in falsely and maliciously charging another with the commission of some public offense criminal in itself, and indictable, and subjecting the party to an infamous punishment, or involving moral turpitude, or the breach of some public trust, or with any matter in relation to his particular trade or vocation, and which, if true, would render him unworthy of employment ; or, lastly, with any other matter or thing by which special injury is sustained. [James Kent, "Commentaries on American Law," 1844]
