haft (n.)
Old English hæft "handle," especially of a cutting or thrusting instrument, related to hæft "fetter, bond; captive, slave," via a common notion of "a seizing, a thing seized," from Proto-Germanic *haftjam (source also of Old Saxon haft "captured;" Dutch hecht, Old High German hefti, German Heft "handle;" German Haft "arrest"), from PIE root *kap- "to grasp." To haven other haeftes in hand "have other hafts in hand" was a 14c.-15c. way of saying "have other business to attend to."
hag (n.)
early 13c., "repulsive old woman" (rare before 16c.), probably from Old English hægtes, hægtesse "witch, sorceress, enchantress, fury," shortened on the assumption that -tes was a suffix. The Old English word is from Proto-Germanic *hagatusjon, which is of unknown origin. Dutch heks, German Hexe "witch" are similarly shortened from cognate Middle Dutch haghetisse, Old High German hagzusa.

The first element probably is cognate with Old English haga "enclosure, portion of woodland marked off for cutting" (see hedge (n.)). Old Norse had tunriða and Old High German zunritha, both literally "hedge-rider," used of witches and ghosts. The second element in the prehistoric compound may be connected with Norwegian tysja "fairy; crippled woman," Gaulish dusius "demon," Lithuanian dvasia "spirit," from PIE *dhewes- "to fly about, smoke, be scattered, vanish."

One of the magic words for which there is no male form, suggesting its original meaning was close to "diviner, soothsayer," which were always female in northern European paganism, and hægtesse seem at one time to have meant "woman of prophetic and oracular powers" (Ælfric uses it to render the Greek "pythoness," the voice of the Delphic oracle), a figure greatly feared and respected. Later, the word was used of village wise women.

Haga is also the haw- in hawthorn, which is an important tree in northern European pagan religion. There may be several layers of folk etymology here. Confusion or blending with heathenish is suggested by Middle English hæhtis, hægtis "hag, witch, fury, etc.," and haetnesse "goddess," used of Minerva and Diana.

If the hægtesse once was a powerful supernatural woman (in Norse it is an alternative word for Norn, any of the three weird sisters, the equivalent of the Fates), it might originally have carried the hawthorn sense. Later, when the pagan magic was reduced to local scatterings, it might have had the sense of "hedge-rider," or "she who straddles the hedge," because the hedge was the boundary between the civilized world of the village and the wild world beyond. The hægtesse would have a foot in each reality. Even later, when it meant the local healer and root collector, living in the open and moving from village to village, it may have had the mildly pejorative Middle English sense of hedge- (hedge-priest, etc.), suggesting an itinerant sleeping under bushes. The same word could have contained all three senses before being reduced to its modern one.
hag-ridden (n.)
1680s, "ridden by hags or witches," past-participle adjective from hag-ride (1660s); from hag (n.) + ridden. From 1702 as "oppressed, harassed;" 1758 as "afflicted by nightmares."

mid-14c., "a kind of door latch," and said to be still the name for rings for raising thumb-latches in the north of England. It appears to be what it looks like: what you say when you open the door ("have good day," as in the 1414 record of them as hafgooddays).
haggard (adj.)
1560s, "wild, unruly" (originally in reference to hawks), from Middle French haggard, probably from Old French faulcon hagard "wild falcon," literally "falcon of the woods," from hagard, hagart, from Middle High German hag "hedge, copse, wood," from Proto-Germanic *hagon, from PIE root *kagh- "to catch, seize;" also "wickerwork, fence" (see hedge (n.)). OED, however, finds this derivation "very doubtful." Sense perhaps reinforced by Low German hager "gaunt, haggard."

haggis (n.)

Perhaps from Old French hacheiz "minced meat," from agace "magpie," on analogy of the odds and ends the bird collects. The other theory [Klein, Watkins, Middle English Dictionary] traces it to Old English haggen "to chop," or directly from Old Norse höggva "to hew, cut, strike, smite" (see hack (v.1)).
haggle (v.)
1570s, "to cut unevenly, mangle in cutting" (implied in haggler "clumsy workman"), frequentative of haggen "to chop" (see hack (v.1)). Sense of "argue about price" first recorded c. 1600, probably from notion of chopping away. Related: Haggled; haggling.

before vowels hagi-, word-forming element meaning "of a saint, saintly, holy," from Greek hagios "sacred, devoted to the gods" (of things), "holy, pure" (of persons), in Ecclesiastical Greek, "a saint," which is perhaps from PIE *yag- "to worship, reverence" (source also of Greek agnos "chaste," Sanskrit yajati "reveres (a god) with sacrifices, worships," Old Persian ayadana "temple").

"Traditionally, there is mention of a season of the year somewhere in a haiku, as a means of establishing the poem's tone, though this may be only the slightest suggestion." [Miller Williams, "Patterns of Poetry," Baton Rouge: Louisiana State University, 1986].
hail (interj.)
