assize (n.)youdaoicibaDictYouDict[assize 词源字典]
"session of a law court," c. 1300 (attested from mid-12c. in Anglo-Latin), from Old French assise "session, sitting of a court" (12c.), properly fem. past participle of asseoir "to cause to sit," from Latin assidere "to sit beside" (see assess). Originally "all legal proceedings of the nature of inquests or recognitions;" hence sessions held periodically in each county of England to administer civil and criminal justice.[assize etymology, assize origin, 英语词源]
cholera (n.)youdaoicibaDictYouDict
late 14c., "bile, melancholy" (originally the same as choler), from Middle French cholera or directly from Late Latin cholera, from Greek kholera "a type of disease characterized by diarrhea, supposedly caused by choler" (Celsus), from khole "gall, bile," from khloazein "to be green," from khloros (see Chloe). But another sense of khole was "drainpipe, gutter."

Revived 1560s in classical sense as a name for a severe digestive disorder (rarely fatal to adults); and 1704 (especially as cholera morbus), for a highly lethal disease endemic in India, periodically breaking out in global epidemics, especially that reaching Britain and America in the early 1830s.
guitar (n.)youdaoicibaDictYouDict
lute-like musical instrument, 1620s, from French guitare, which was altered by Spanish and Provençal forms from Old French guiterre, earlier guiterne, from Latin cithara, from Greek kithara "cithara," a triangular seven-stringed musical instrument related to the lyre, perhaps from Persian sihtar (see sitar). The name reached English several times, including giterne (early 14c., from Old French), in reference to various stringed, guitar-like instruments; the modern word is also directly from Spanish guitarra (14c.), which ultimately is from the Greek. The Arabic word is perhaps from Spanish or Greek, though often the relationship is said to be the reverse. The modern guitar is one of a large class of instruments used in all countries and ages but particularly popular in Spain and periodically so in France and England. Other 17c, forms of the word in English include guittara, guitarra, gittar, and guitarre. Compare zither, gittern.
