word-forming element meaning "state or condition of being," from Old English -had "condition, quality, position" (as in cildhad "childhood," preosthad "priesthood," werhad "manhood"), cognate with German -heit/-keit, Dutch -heid, Old Frisian and Old Saxon -hed, all from Proto-Germanic *haidus "manner, quality," literally "bright appearance," from PIE (s)kai- (1) "bright, shining" (Cognates: Sanskrit ketu "brightness, appearance"). Originally a free-standing word (see hade); in Modern English it survives only in this suffix.
H Look up H at Dictionary.com
eighth letter of the alphabet; it comes from Phoenician, via Greek and Latin. In Phoenician it originally had a rough guttural sound like German Reich or Scottish loch. In Greek at first it had the value of Modern English -h-, and with this value it passed into the Latin alphabet via Greek colonies in Italy. Subsequently in Greek it came to be used for a long "e" sound; the "h" sound being indicated by a fragment of the letter, which later was reduced to the aspiration mark. In Germanic it was used for the voiceless breath sound when at the beginning of words, and in the middle or at the end of words for the rough guttural sound, which later came to be written -gh.

The sound became totally silent in Vulgar Latin and in the languages that emerged from it; thus the letter was omitted in Old French and Italian, but it was restored pedantically in French and Middle English spelling, and often later in English pronunciation. Thus Modern English has words ultimately from Latin with missing -h- (able, from Latin habile); with a silent -h- (heir, hour); with a formerly silent -h- now often vocalized (humble, humor, herb); and even a few with an excrescent -h- fitted in confusion to words that never had one (hostage, hermit). Relics of the formerly unvoiced -h- persist in pedantic insistence on an historical (object) and in obsolete mine host.

The pronunciation "aitch" was in Old French (ache "name of the letter H"), and is from a presumed Late Latin *accha (compare Italian effe, elle, emme), with the central sound approximating the rough, guttural value of the letter in Germanic. In earlier Latin the letter was called ha. The use in digraphs (as in -sh-, -th-) goes back to the ancient Greek alphabet, which used it in -ph-, -th-, -kh- until -H- took on the value of a long "e" and the digraphs acquired their own characters. The letter passed into Roman use before this evolution, and thus retained there more of its original Semitic value.
ha (interj.) Look up ha at Dictionary.com
natural expression of surprise, distress, etc.; early 14c., found in most European languages (including Latin and Old French) but not in Old English (which did, however, have ha-ha).
ha-ha Look up ha-ha at Dictionary.com
also haha, used of laughter since ancient times; Old English ha ha. Also in Greek (ha ha, in Euripides, Aristophanes), Latin (hahae). A different attempt at representation in English is py-hy (1580s). Sometimes interchanged with ah and expressing surprise, distress, etc. A ha-ha (1712), from French, was "an obstacle interrupting one's way sharply and disagreeably;" so called because it "surprizes ... and makes one cry Ah! Ah!" [Alexander Le Blond, "The Theory and Practice of Gardening," 1712].

haberdasher (n.) Look up haberdasher at Dictionary.com
early 14c. (late 13c. as a surname), "seller of small articles of trade" (caps, purses, beads, thread, stationery, etc.), from Anglo-French, where apparently it was an agent noun formation from hapertas "small wares," also a kind of fabric, a word of unknown origin. Sense of "dealer in men's wares" is 1887 in American English, via intermediate sense of "seller of caps." Middle English haberdash (n.) "small articles of trade sold by a haberdasher" appears to be a back-formation from this word, and the verb haberdash is late (1630s) and rare.
haberdashery (n.) Look up haberdashery at Dictionary.com
early 15c., Anglo-French, "goods sold by a haberdasher," from haberdasher + -y (2). Meaning "a haberdasher's shop" is recorded from 1813, with perceived meaning shading to -ery.
habiliment (n.) Look up habiliment at Dictionary.com
often habiliments, early 15c., "munitions, weapons," from Middle French habillement, from abiller "prepare or fit out," probably from abile, habile "fit, suitable" (see able).

Sense of "clothing, dress" developed late 15c., by association with habit (n.).
habilitate (v.) Look up habilitate at Dictionary.com
c. 1600 (transitive) "to qualify," from Medieval Latin habilitatus, past participle of habilitare, from habile "fit, suitable" (see able). Intransitive meaning "obtain necessary qualifications" is from 1881. Related: Habilitated; habilitation.

The basic sense of the root probably is "to hold," which can be either in offering or in taking.

Meaning "clothing generally" is from late 14c. Meaning "customary practice, usual mode of action" is early 14c. Drug sense is from 1887. The Latin word was applied to both inner and outer states of being, and both senses were taken in English, though meaning of "dress" now is restricted to monks and nuns.

hack (v.1) Look up hack at Dictionary.com
"to cut roughly, cut with chopping blows," c. 1200, from verb found in stem of Old English tohaccian "hack to pieces," from West Germanic *hakkon (cognates: Old Frisian hackia "to chop or hack," Dutch hakken, Old High German hacchon, German hacken), from PIE *keg- "hook, tooth" (see hook (n.)). Perhaps influenced by Old Norse höggva "to hew, cut, strike, smite" (which is unrelated, from PIE *kau- "to hew, strike;" see hew). Slang sense of "cope with" (as in can't hack it) is first recorded in American English 1955, with a sense of "get through by some effort," as a jungle (phrase hack after "keep working away at" is attested from late 14c.).

hack (n.2) Look up hack at Dictionary.com
"person hired to do routine work," c. 1700, ultimately short for hackney "an ordinary horse, horse for general service (especially for driving or riding, as opposed to war, hunting, or hauling)," c. 1300. This word is probably from the place name Hackney, Middlesex. Apparently nags were raised on the pastureland there in early medieval times. Extended sense of "horse for hire" (late 14c.) led naturally to "broken-down nag," and also "prostitute" (1570s) and "a drudge" (1540s), especially a literary one, one who writes according to direction or demand. Sense of "carriage for hire" (1704) led to modern slang for "taxicab." As an adjective, 1734, from the noun. Hack writer is first recorded 1826, though hackney writer is at least 50 years earlier. Hack-work is recorded from 1851.
hack (v.2) Look up hack at Dictionary.com
"illegally enter a computer system," by 1984; apparently a back-formation from hacker. Related: Hacked; hacking (1975 in this sense). Earlier verb senses were "to make commonplace" (1745), "make common by everyday use" (1590s), "use (a horse) for ordinary riding" (1560s), all from hack (n.2).

hackamore (n.) Look up hackamore at Dictionary.com
halter chiefly used for breaking horses, 1850, American English, of uncertain origin. OED and Klein suggests a corruption of Spanish jaquima (earlier xaquima) "halter, headstall of a horse," which Klein suggests is from Arabic shakimah "bit of a bridle, curb, restraint."
hacker (n.) Look up hacker at Dictionary.com
early 13c. (as a surname), "a chopper, cutter," perhaps also "one who makes hacking tools," agent noun from hack (v.1).

Meaning "one who gains unauthorized access to computer records" is attested by 1975, and this sense seems to suggest hack (v.1), but the computer use is said to be from slightly earlier tech slang sense of "one who works like a hack at writing and experimenting with software, one who enjoys computer programming for its own sake," reputedly a usage that evolved at Massachusetts Institute of Technology (however an MIT student from the late 1960s recalls hack (n.) being used then and there in the general sense of "creative prank." This suggests rather a connection with hack (n.2) via the notion of "plodding, routine work." There may be a convergence of both words here.
hackle (n.) Look up hackle at Dictionary.com
Old English hacele "coat, cloak, vestment, mantle" (cognate with Old High German hachul, Gothic hakuls "cloak;" Old Norse hekla "hooded frock"), of uncertain origin. The same word with a sense of "bird plumage" is first recorded early 15c., though this might be from unrelated Middle English hackle "flax comb" (see heckle (n.)) on supposed resemblance of comb to ruffled feathers, or from an unrecorded continental Germanic word. Metaphoric extension found in phrases such as raise (one's) hackles (as a cock does when angry) is by 1881.
hackney (n.) Look up hackney at Dictionary.com
"small saddle horse let out for hire," c. 1300, from place name Hackney (late 12c.), Old English Hacan ieg "Haca's Isle" (or possibly "Hook Island"), the "isle" element here meaning dry land in a marsh. Now well within London, it once was pastoral and horses apparently were kept there. Hence the use for riding horses, with subsequent deterioration of sense (see hack (n.2)). Old French haquenée "ambling nag" is an English loan-word.
