cack-handed [cack-handed 词源字典]: cack-handed: [19] Cack comes from a 15thcentury dialect verb meaning ‘defecate’, which probably came from Middle Dutch cacken. It goes back via Latin cacāre to an ultimate Indo- European base *kak-, from which a lot of other Indo-European languages get words connected with ‘excrement’. The connection with cackhanded is usually explained as being that clumsy people make a mess; on this view ‘left-handed’, which cack-handed also means, is a secondary sense derived from ‘clumsy’. It may be nearer the mark to place ‘left-handed’ first, however, bearing in mind the traditional role of the left hand in many cultures for wiping the anus.
[cack-handed etymology, cack-handed origin, 英语词源]
handicap: handicap: [17] The word handicap originally denoted a sort of game of chance in which one person put up one of his or her personal possessions against an article belonging to someone else (for example one might match a gold watch against the other’s horse) and an umpire was appointed to adjudicate on the respective values of the articles. All three parties put their hands into a hat, together with a wager, and on hearing the umpire’s verdict the two opponents had to withdraw them in such a way as to indicate whether they wished to proceed with the game.

If they agreed, either in favour of proceeding or against, the umpire took the money; but if they disagreed, the one who wanted to proceed took it. It was the concealing of the hands in the hat that gave the game its name hand in cap, hand i’ cap, source of modern English handicap. In the 18th century the same term was applied to a sort of horse race between two horses, in which an umpire decided on a weight disadvantage to be imposed on a superior horse and again the owners of the horses signalled their assent to or dissent from his adjudication by the way in which they withdrew their hands from a hat.

Such a race became known as a handicap race, and in the 19th century the term handicap first broadened out to any contest in which inequalities are artificially evened out, and was eventually transferred to the ‘disadvantage’ imposed on superior contestants – whence the main modern meaning, ‘disadvantage, disability’.
stock: stock: [OE] The word stock originally denoted a ‘tree-trunk’. It came from a prehistoric Germanic *stukkaz, which also produced German stock ‘stick’ and Swedish stock ‘log’. The lineal semantic descent to the stocks [14], a punishment device made from large pieces of wood, is clear enough, but how stock came to be used for a ‘supply, store’ (a sense first recorded in the 15th century) is more of a mystery.

It may be that a tradesman’s supply of goods was thought of metaphorically as the trunk of a tree, from which profits grew like branches; and another possibility is that the usage was inspired by an unrecorded application of stock to a wooden storage chest or money box. Stock ‘broth’ was so named (in the 18th century, apparently) because one keeps a ‘stock’ of it on hand in the stockpot, for use at need.

The original notion of a stout piece of wood is preserved in the derivative stocky [14], and also in stock-still [15] – literally ‘as still as a log’.
handicap (n.): 1650s, from hand in cap, a game whereby two bettors would engage a neutral umpire to determine the odds in an unequal contest. The bettors would put their hands holding forfeit money into a hat or cap. The umpire would announce the odds and the bettors would withdraw their hands -- hands full meaning that they accepted the odds and the bet was on, hands empty meaning they did not accept the bet and were willing to forfeit the money. If one forfeited, then the money went to the other. If both agreed either on forfeiting or going ahead with the wager, then the umpire kept the money as payment. The custom, though not the name, is attested from 14c. ("Piers Plowman").

Reference to horse racing is 1754 (Handy-Cap Match), where the umpire decrees the superior horse should carry extra weight as a "handicap;" this led to sense of "encumbrance, disability" first recorded 1890. The main modern sense, "a mental or physical disability," is the last to develop, early 20c.
morganatic (adj.): 1727, from French morganatique (18c.), from Medieval Latin matrimonium ad morganaticam "marriage of the morning," probably from Old High German *morgangeba (Middle High German morgengabe) "morning gift," corresponding to Old English morgengifu (see morn + gift). In an unequal marriage between a man of royal blood and a common woman, this was a gift traditionally given to the wife on the morning after consummation, representing the only share she and her children may claim in the husband's estate. Also known as left-handed marriage, because the groom gives the bride his left hand instead of his right, but sometimes this latter term is used of a class of marriage (especially in Germany) where the spouse of inferior rank is not elevated, but the children inherit rights of succession. Related: Morganatically.
quarterstaff (n.): also quarter-staff, 1540s (quarter-stroke "stroke with a quarterstaff" is attested from early 15c.), stout pole, six to eight feet long (six-and-a-half sometimes is given as the standard length), tipped with iron, formerly a weapon used by the English peasantry. From staff (n.); the quarter is of uncertain signification. According to one theory, favored by fencing manuals, etc., it likely is in reference to operation of the weapon:
It was grasped by one hand in the middle, and by the other between the middle and the end. In the attack the latter hand shifted from one quarter of the staff to the other, giving the weapon a rapid circular motion, which brought the ends on the adversary at unexpected points. [Century Dictionary]
Linguists tend to prefer an explanation from woodcutting, perhaps a reference to a cut of lumber known as a quarter, but contemporary evidence is wanting for either conjecture.
yakuza (n.): traditional Japanese organized crime cartel, literally "eight-nine-three" (ya, ku, sa) the losing hand in the traditional baccarat-like Japanese card game Oicho-Kabu. The notion may be "good for nothing," or "bad luck" (such as that suffered by someone who runs afoul of them), or it may be a reference to the fact that a player who draws this hand requires great skill to win.
