jerry-built [jerry-built 词源字典]: jerry-built: [19] In the absence of any watertight evidence, many theories have been put forward to account for this adjective (first recorded in 1869). One (touted in newspaper correspondence as early as 1884) holds that it immortalizes the incompetence of a firm of Liverpool builders named Jerry, but no proof of that has ever been found. Another would link it, ingeniously, with the walls of Jericho, which fell down as soon as Joshua blew his trumpet.
[jerry-built etymology, jerry-built origin, 英语词源]
ingenious (adj.): early 15c., "intellectual, talented," from Middle French ingénieux "clever, ingenious" (Old French engeignos), from Latin ingeniosus "of good capacity, full of intellect; clever, gifted with genius," from ingenium "innate qualities, ability," literally "that which is inborn," from in- "in" (see in- (2)) + gignere, from PIE *gen- "produce" (see genus). Sense of "skillful, clever at contrivance" first recorded 1540s. In a sense of "crafty, clever, skillful" Middle English had enginous (mid-14c.), from Old French engeignos, also engineful "skillful (in war)" (c. 1300). Related: Ingeniously; ingeniousness.
tinker (n.): "mender of kettles, pots, pans, etc.," late 14c. (mid-13c. as a surname), of uncertain origin. Some connect the word with the sound made by light hammering on metal. Tinker's damn "something slight and worthless" is from 1824, probably preserving tinkers' reputation for free and casual use of profanity; the plain and simple etymology is not good enough for some writers, and since 1877 an ingeniously elaborate but baseless derivation has been circulated claiming the second word is really dam.
Heath Robinson: "Ingeniously or ridiculously over-complicated in design or construction", Early 20th century: named after W. Heath Robinson (see Robinson, Heath).
