punch: English has three distinct words punch, not counting the capitalized character in the Punch and Judy show, but two of them are probably ultimately related. Punch ‘hit’ [14] originated as a variant of Middle English pounce ‘pierce, prod’. This came from Old French poinsonner ‘prick, stamp’, a derivative of the noun poinson ‘pointed tool’ (source of the now obsolete English puncheon ‘pointed tool’ [14]).

And poinson in turn came from Vulgar Latin *punctiō, a derivative of *punctiāre ‘pierce, prick’, which went back to the past participle of Latin pungere ‘prick’ (source of English point, punctuation, etc). Punch ‘tool for making holes’ [15] (as in ‘ticket punch’) probably originated as an abbreviated version of puncheon. Punch ‘drink’ [17] is said to come from Hindi pānch, a descendant of Sanskrit panchan ‘five’, an allusion to the fact that the drink is traditionally made from five ingredients: spirits, water, lemon juice, sugar, and spice.

This has never been definitely established, however, and an alternative possibility is that it is an abbreviation of puncheon ‘barrel’ [15], a word of uncertain origin. The name of Mr Punch [17] is short for Punchinello, which comes from a Neapolitan dialect word polecenella. This may have been a diminutive of Italian polecena ‘young turkey’, which goes back ultimately to Latin pullus ‘young animal, young chicken’ (source of English poultry).

It is presumably an allusion to Punch’s beaklike nose.

Perhaps you are some great big chief, who has a lot to say.
Who lords it o'er the common herd who chance to come your way;
Well, here is where your arrogance gets a dreadful shock,
When you march up, like a private, salute, and PUNCH THE CLOCK.

[from "Punch the Clock," by "The Skipper," "The Commercial Telegraphers' Journal," May 1912]
Specialized sense "to hit with the fist" first recorded 1520s. Compare Latin pugnare "to fight with the fists," from a root meaning "to pierce, sting." In English this was probably influenced by punish; "punch" or "punsch" for "punish" is found in documents from 14c.-15c.:
punchyth me, Lorde, and spare my blyssyd wyff Anne. [Coventry Mystery Plays, late 15c.]
To punch (someone) out "beat up" is from 1971.
punch (n.1)youdaoicibaDictYouDict
"pointed tool for making holes or embossing," late 14c., short for puncheon (mid-14c.), from Old French ponchon, poinchon "pointed tool, piercing weapon," from Vulgar Latin *punctionem (nominative *punctio) "pointed tool," from past participle stem of Latin pungere "to prick" (see pungent). From mid-15c. as "a stab, thrust;" late 15c. as "a dagger." Meaning "machine for pressing or stamping a die" is from 1620s.
punch (n.2)youdaoicibaDictYouDict
type of mixed drink, 1630s, traditionally since 17c. said to derive from Hindi panch "five," in reference to the number of original ingredients (spirits, water, lemon juice, sugar, spice), from Sanskrit panchan-s, from pancha "five" (see five). But there are difficulties (see OED), and connection to puncheon (n.1) is not impossible.
Punch (n.)youdaoicibaDictYouDict
the puppet show star, 1709, shortening of Punchinello (1666), from Italian (Neapolitan) Pollecinella, Pollecenella, diminutive of pollecena "turkey pullet," probably in allusion to his big nose.

punch (n.3)youdaoicibaDictYouDict
"a quick blow with the fist," by 1570s, probably from punch (v.). In early use also of blows with the foot or jabs with a staff or club. Originally especially of blows that sink in to some degree ("... whom he unmercifully bruises and batters from head to foot: here a slap in the chaps, there a black eye, now a punch in the stomach, and then a kick on the breech," "Monthly Review," 1763). Figurative sense of "forceful, vigorous quality" is recorded from 1911. To beat (someone) to the punch in the figurative sense is from 1915, a metaphor from boxing (attested by 1913). Punch line (also punch-line) is from 1915 (originally in popular-song writing); punch-drunk is from 1915 (alternative form slug-nutty is from 1933).
