What does Boxing Day have to do with boxing?
c.1300, hauk, earlier havek (c.1200), from Old English hafoc (W. Saxon), heafuc (Mercian), heafoc, from Proto-Germanic *habukaz (cf. Old Norse haukr, Old Saxon habuc, Middle Dutch havik, Old High German habuh, German Habicht "hawk"), from a root meaning "to seize," from PIE *kap- "to grasp" (cf. Russian kobec "a kind of falcon;" see capable). Transferred sense of "militarist" attested from 1962.
"to sell in the open, peddle," late 15c., back-formation from hawker "itinerant vendor" (c.1400), from Middle Low German höken "to peddle, carry on the back, squat," from Proto-Germanic *huk-. Related: Hawked; hawking. Despite the etymological connection with stooping under a burden on one's back, a hawker is technically distinguished from a peddler by use of a horse and cart or a van.
"to hunt with a hawk," mid-14c., from hawk (n.).
"to clear one's throat," 1580s, imitative.
To clear one's throat; cough up and spit: let out of their cells to wash, hawk, stretch (1583+)
A imitation Indian haircut affected by punk rockers; mohawk: egg or soap it into the hawk (1980s+)
The cold winter wind: Well, looks like the hawk is getting ready to hit the scene and send temperatures down

(Heb. netz, a word expressive of strong and rapid flight, and hence appropriate to the hawk). It is an unclean bird (Lev. 11:16; Deut. 14:15). It is common in Syria and surrounding countries. The Hebrew word includes various species of Falconidae, with special reference perhaps to the kestrel (Falco tinnunculus), the hobby (Hypotriorchis subbuteo), and the lesser kestrel (Tin, Cenchris). The kestrel remains all the year in Palestine, but some ten or twelve other species are all migrants from the south. Of those summer visitors to Palestine special mention may be made of the Falco sacer and the Falco lanarius. (See NIGHT-HAWK ØT0002729.)
