harvest (n.)
Old English hærfest "autumn, period between August and November," from Proto-Germanic *harbitas (cognates: Old Saxon hervist, Old Frisian and Dutch herfst, German Herbst "autumn," Old Norse haust "harvest"), from PIE *kerp- "to gather, pluck, harvest" (cognates: Sanskrit krpana- "sword," krpani "shears;" Greek karpos "fruit," karpizomai "make harvest of;" Latin carpere "to cut, divide, pluck;" Lithuanian kerpu "cut;" Middle Irish cerbaim "cut").

The borrowing of autumn and the use of fall in a seasonal sense gradually focused the meaning of harvest to "the time of gathering crops" (mid-13c.), then to the action itself and the product of the action (after c.1300). Figurative use by 1530s. Harvest home (1590s) is the occasion of bringing home the last of the harvest; harvest moon (1706) is that which is full within a fortnight of the autumnal equinox.

The hash marks on a football field were so called 1960s, from similarity to hash marks, armed forces slang for "service stripes on the sleeve of a military uniform" (1909), which supposedly were called that because they mark the number of years one has had free food (hash (n.1)) from the Army; but perhaps there is a connection with the noun form of hatch (v.2).

hasty (adj.)
mid-14c., "speedy, quick," by 1500s replacing or nativizing earlier hastif (c.1300) "eager, impetuous," from Old French hastif "speedy, rapid; forward, advanced; rash, impetuous" (12c., Modern French hâtif), from haste (see haste). Meaning "requiring haste" is late 14c. (the sense in hasty pudding, 1590s, so called because it was made quickly); that of "rash" is from early 15c. Related: Hastiness. Old French also had a form hasti (for loss of terminal -f, compare joli/jolif, etc.), which may have influenced the form of the English word.
The termination was doubtless from the first identified with native -i, -y, from OE -ig; and it is noticeable that the other Teutonic langs. have formed corresponding adjs. of that type: Du. haastig, Ger., Da., Sw. hastig. [OED]
hat (n.)
Old English hæt "hat, head covering," from Proto-Germanic *hattuz "hood, cowl" (cognates: Frisian hat, Old Norse hattr), from PIE root *kadh- "cover, protect" (cognates: Lithuanian kudas "tuft or crest of a bird," Latin cassis "helmet").

hat trick (n.)
1879, originally from cricket, "taking three wickets on three consecutive deliveries;" extended to other sports (especially ice hockey) c.1909. Allegedly because it entitled the bowler to receive a hat from his club commemorating the feat (or entitled him to pass the hat for a cash collection), but also influenced by the image of a conjurer pulling things from his hat (attested by 1876). The term was used earlier for a different sort of magic trick:
Place a glass of liquor on the table, put a hat over it, and say, "I will engage to drink every drop of that liquor, and yet I'll not touch the hat." You then get under the table; and after giving three knocks, you make a noise with your mouth, as if you were swallowing the liquor. Then, getting from under the table, say "Now, gentlemen, be pleased to look." Some one, eager to see if you have drunk the liquor, will raise the hat; when you instantly take the glass and swallow the contents, saying, "Gentlemen I have fulfilled my promise: you are all witnesses that I did not touch the hat." ["Wit and Wisdom," London, 1860]
hatch (v.1)
"to produce young from eggs by incubation," from Middle English hachen (early 13c.), probably from an unrecorded Old English *hæccan, of unknown origin, related to Middle High German, German hecken "to mate" (used of birds). Meaning "to come forth from an egg" is late 14c. Figurative use (of plots, etc.) is from early 14c. Related: Hatched; hatching.

hatchet (n.)
c.1300 "small ax" (mid-12c. in surnames), from Old French hachete, diminutive of hache "ax, battle-axe, pickaxe," possibly from Frankish *happja or some other Germanic source, from Proto-Germanic *hapjo- (cognates: Old High German happa "sickle, scythe"), from PIE root *kop- "to beat, strike" (cognates: Greek kopis "knife;" Lithuanian kaplys "hatchet," kapoti "cut small;" Old Church Slavonic skopiti "castrate").

In Middle English, hatch itself was used in a sense "battle-axe." In 14c., hang up (one's) hatchet meant "stop what one is doing."
