chiropodist (n.)youdaoicibaDictYouDict[chiropodist 词源字典]
1785, from chiro- "hand" + pod-, stem of Greek pous "foot," from PIE root *ped- (1) "a foot" (see foot (n.)) + -ist. Probably coined by Canadian-born U.S. healer Daniel Palmer (1845-1913); originally they treated both hands and feet. A much-maligned word among classicists, who point out it could mean "having chapped feet" but probably doesn't, and in that case it is an etymological garble and no one can say for sure what it is meant to signify.

due (adj.)youdaoicibaDictYouDict
early 14c., "customary, regular;" mid-14c., "owing, payable," from Old French deu, past participle of devoir "to owe," from Latin debere "to owe" (see debt).

In reference to points of the compass (as in due east) it is attested from c. 1600, originally nautical, from notion of "fitting, rightful." As an adverb from 1590s; as a noun from early 15c. Prepositional phrase due to (much maligned by grammarians) is from 1897.
malign (v.)youdaoicibaDictYouDict
"to slander," mid-15c., from earlier more literal sense of "to plot, to contrive" (early 15c.), from Old French malignier "to plot, deceive, pervert," from Late Latin malignare "to do maliciously," from malignus (see malign (adj.)). Related: Maligned; maligning.
suicide (n.)youdaoicibaDictYouDict
"deliberate killing of oneself," 1650s, from Modern Latin suicidium "suicide," from Latin sui "of oneself" (genitive of se "self"), from PIE *s(u)w-o- "one's own," from root *s(w)e- (see idiom) + -cidium "a killing" (see -cide). Probably an English coinage; much maligned by Latin purists because it "may as well seem to participate of sus, a sow, as of the pronoun sui" [Phillips]. The meaning "person who kills himself deliberately" is from 1728. In Anglo-Latin, the term for "one who commits suicide" was felo-de-se, literally "one guilty concerning himself."
Even in 1749, in the full blaze of the philosophic movement, we find a suicide named Portier dragged through the streets of Paris with his face to the ground, hung from a gallows by his feet, and then thrown into the sewers; and the laws were not abrogated till the Revolution, which, having founded so many other forms of freedom, accorded the liberty of death. [W.E.H. Lecky, "History of European Morals," 1869]
In England, suicides were legally criminal if of age and sane, but not if judged to have been mentally deranged. The criminal ones were mutilated by stake and given degrading burial in highways until 1823. Suicide blonde (one who has "dyed by her own hand") first attested 1921. Baseball suicide squeeze is attested from 1937.
