late 14c., "a dog;" late 15c., "noisy fellow;" agent noun from bark (v.). Specific sense of "loud assistant in an auction, store, or show" is from 1690s.

surname attested from mid-12c., literally "dweller at the hares' wood." Harley Street in London from the 1830s was associated with eminent physicians and used metonymically for "medical specialists collectively." As a type of motorcycle, by 1968, short for Harley-Davidson, the motorcycle manufacturer founded in Milwaukee, Wisconsin, U.S., 1905 by engine designer William S. Harley (1880-1943) and Arthur Davidson.

1744, from Latinized form of surname of Robert Harley, Earl of Oxford (1661-1724) and his son Edward, in reference to the library of several thousand books and MSS they collected and sold in 1753 to the British Museum.

surname of the famous family of English authors; the current version is a scholarly convention and until after the deaths of the sisters it was variously spelled and accented. Juliet Barker ("The Brontës," 1994), writes that their father was registered at Cambridge in 1802 as "Patrick Branty," which he soon corrected to Bronte. The family was Irish Protestant. "At a time when literacy was extremely rare, especially in rural districts of Ireland, the usual Brontë name was spelt in a variety of ways, ranging from Prunty to Brunty and Bruntee, with no consistent version until Patrick himself decided on 'Bronte'." [Barker]

1796, "a painting on a revolving cylindrical surface," representing scenes too extended to be beheld all at once, coined c. 1789 by inventor, Irish artist Robert Barker, literally "a complete view," from pan- "all" + Greek horama "sight, spectacle, that which is seen," from horan "to look, see," which is possibly from PIE root *wer- (3) "to perceive, observe." Meaning "comprehensive survey, complete or entire view" is by 1801.

mid-14c., hogge, but probably in Old English (implied late 12c. in hogaster), "a swine," especially a castrated male, "swine reared for slaughter" (usually about a year old), also used by stockmen for "young sheep before the first shearing" (early 14c.) and for "horse older than one year," suggesting the original sense had to do with age, not type of animal. Possibility of British Celtic origin [Watkins, etc.] is regarded by OED as "improbable."

Extended to the wild boar by late 15c. As a term of opprobrium for a greedy or gluttonous person, c. 1400. Meaning "Harley-Davidson motorcycle" is attested from 1967. Road hog is attested from 1886, hence hog "rude person heedless of the convenience or safety of others" (1906). To go hog-wild is American English from 1904. Hog in armor "awkward or clumsy person in ill-fitting attire" is from 1650s (later used of the armadillo).

Phrase go the whole hog (1828, American English) is sometimes said to be from the butcher shop option of buying the whole slaughtered animal (at a discount) rather than just the choice bits. But it is perhaps rather from the allegorical story (recorded in English from 1779) of Muslim sophists, forbidden by their faith from eating a certain unnamed part of the hog, who debated which part was intended and in the end managed to exempt the whole of it from the prohibition.

Had he the sinful part express'd,

They might, with safety, eat the rest.

But for one piece, they thought it hard,

From the whole hog to be debarr'd

And set their wits to work, to find

What joint the prophet had in mind.
