Of unknown origin, though newspapers of the day printed myriad fanciful stories concocted to account for it. A guess perhaps better than average is that it is from German dialectal (Bavarian) Huddellump "ragamuffin" [Barnhart].
What the derivation of the word "hoodlum" is we could never satisfactorily ascertain, though several derivations have been proposed; and it would appear that the word has not been very many years in use.

hoof (n.): Old English hof "hoof," from Proto-Germanic *hofaz (source also of Old Saxon, Old Frisian hof, Old Norse hofr, Danish hov, Dutch hoef, German Huf "hof"), from PIE *kop- "to beat, strike" (source also of Sanskrit saphah "hoof," Polish kopyto "hoof;" see hatchet (n.)). For spelling, see hood (n.1).
A hoof differs from a nail or claw only in being blunt and large enough to inclose the end of the limb; and almost every gradation is to be found between such structures as the human nails, or the claws of a cat, and the hoofs of a horse or an ox. The substance is the same in any case, and the same as horn, being modified and greatly thickened cuticle or epidermis. [Century Dictionary]
Hoof-and-mouth disease is attested from 1887. Phrase on the hoof is from 1750 as "walking;" later it was cattlemen and butchers' slang for "not (yet) slaughtered."
hoof (v.): "having hoofs (of a specified kind)," c. 1500 in compounds, from hoof (n.). Meaning "to walk" (as in hoof it) is from 1640s; slang meaning "to dance" is 1920, American English (implied in hoofer). Related: Hoofing.

For spelling, see hood (n.1).

Also the name of a fireman's tool for tearing into buildings, hence hook-and-ladder (1821). Meaning "holder for a telephone receiver" is from 1885 and continued in use after the mechanism evolved. Boxing sense of "short, swinging blow with the elbow bent" is from 1898. Figurative sense "that which catches, a snare, trap" is from early 15c. Meaning "projecting point of land" is from 1670s; in U.S. use probably reinforced by the Dutch word.
This name is given in New York to several angular points in the North and East rivers; as Corlear's Hook, Sandy Hook, Powles's Hook. [Bartlett, "Dictionary of Americanisms," 1848]
Off the hooks meant "disordered" (16c.), "unhinged" (1610s) and "dead" (1840). By hook or by crook (late 14c.) probably alludes to tools of professional thieves. Hook, line, and sinker "completely" is 1838, a metaphor from angling. Hook-nose (n.) is from 1680s; hook-nosed (adj.) from 1510s. Hook-and-eye as a method of garment fastening is from 1620s.

hook (v.): "to bend like a hook," c. 1200 (transitive); early 15c. (intransitive); see hook (n.).

Sense of "make rugs with a hook" is from 1882. Related: Hooked; hooking.
hookah (n.): also hooka, 1763, via Hindi or Persian or directly from Arabic huqqah "small box, vessel" (through which the smoke is drawn), related to huqq "a hollow place." Extended in Urdu to the whole apparatus.
hooked (adj.): Old English hoced, "shaped like a hook, crooked, curved;" past participle adjective from hook (v.). From mid-14c. as "having hooks;" 1610s as "caught on a hook;" 1925 as "addicted," originally in reference to narcotics. hooked rug is recorded from 1880.
hooker (n.): "one who or that which hooks" in any sense, agent noun from hook (v.). Meaning "prostitute" (by 1845) often is traced to the disreputable morals of the Army of the Potomac (American Civil War) under the tenure of Gen. "Fighting Joe" Hooker (early 1863), and the word might have been popularized by this association at that time (though evidence is wanting). But it is reported to have been in use in North Carolina c. 1845 ("[I]f he comes by way of Norfolk he will find any number of pretty Hookers in the Brick row not far from French's hotel. Take my advice and touch nothing in the shape of a prostitute when you come through Raleigh, for in honest truth the clap is there of luxuriant growth." letter quoted in Norman E. Eliason, "Tarheel Talk," 1956).

One early theory traces it to Corlear's Hook, a section of New York City.
HOOKER. A resident of the Hook, i.e. a strumpet, a sailor's trull. So called from the number of houses of ill-fame frequented by sailors at the Hook (i.e. Corlear's Hook) in the city of New York. [John Russell Bartlett, "Dictionary of Americanisms," 1859]
Or perhaps related to hooker "thief, pickpocket" (1560s). But the word is likely a reference to prostitutes hooking or snaring clients. Hook in the figurative sense of "that by which anyone is attracted or caught" is recorded from early 15c.; and hook (v.) in the figurative sense of "catch hold of and draw in" is attested from 1570s; in reference to "fishing" for a husband or a wife, it was in common use from c. 1800. All of which makes the modern sense seem a natural step. Compare French accrocheuse, raccrocheuse, common slang term for "street-walker, prostitute," literally "hooker" of men.

The family name Hooker (attested from c. 975) would mean "maker of hooks," or else refer to an agricultural laborer who used a hook (compare Old English weodhoc "weed-hook").
hookup (n.): also hook-up, "connection," 1903, from verbal phrase hook up, which is attested from 1825 in reference to yarn; 1925 as "establish a link with." The noun is from 1922 of radio sets, later of television broadcasts. Modern slang verbal sense of "to meet for sex" is attested by 2003.
hooky (n.): also hookey, in the truant sense, 1848, American English (New York City), only in the phrase play hooky; from Dutch hoekje "hide and seek;" or else from hook it, attested since 14c. as "make off, run away," originally "depart, proceed."
hooligan (n.): 1890s, of unknown origin, according to OED, first found in British newspaper police-court reports in the summer of 1898, almost certainly from the variant form of the Irish surname Houlihan, which figured as a characteristic comic Irish name in music hall songs and newspapers of the 1880s and '90s.
As an "inventor" and adapter to general purposes of the tools used by navvies and hodmen, "Hooligan" is an Irish character who occupies week by week the front of a comic literary journal called Nuggets, one of the series of papers published by Mr. James Henderson at Red Lion House. Previous to publication in London, "Hooligan" appears, I believe, in New York in a comic weekly, and in London he is set off against "Schneider," a German, whose contrainventions and adaptations appear in the Garland (a very similar paper to Nuggets), which also comes from Mr. Henderson's office. "Hooligan" and "Schneider" have been running, I should think, for four or five years. ["Notes and Queries," Oct. 15, 1898]
Internationalized 20c. in communist rhetoric as Russian khuligan, opprobrium for "scofflaws, political dissenters, etc."
hooliganism (n.): 1898, from hooligan + -ism.
hoop (n.): late 12c., "circular band, flattened ring," probably from an unrecorded Old English *hop, from Proto-Germanic *hopa- (source also of Old Frisian hop "a hoop, band," Middle Dutch and Dutch hoep "hoop," Old Norse hop "a small bay").

Hoosier: "native or resident of Indiana," by c. 1830, American English, of unknown origin; newspapers in the 1830s published fanciful explanations, some still repeated, "none authenticated by evidence" [Century Dictionary]. Said to have been first printed Jan. 1, 1833, in the "Indianapolis Journal," in a poem, "The Hoosiers Nest," by John Finely, which poem was said to have been written in 1830 ["The Word Hoosier," "Indiana Historical Society Publications," vol. IV, No. 2, 1907], and to have been in oral use from late 1820s. Seemingly it originated among Ohio River boatmen; perhaps related to English dialectal (Cumberland) hoozer, used of anything unusually large [Barnhart]. For other theories, see the historical society article. The word also has been used generally for "country bumpkin."
hoot (v.): "to call or shout in disapproval or scorn," c. 1600, probably related to or a variant of Middle English houten, huten "to shout, call out" (c. 1200), which is more or less imitative of the sound of the thing. First used of bird cries, especially that of the owl, mid-15c. Meaning "to laugh" is from 1926. Related: Hooted; hooting. A hoot owl (1826) is distinguished from a screech owl.
