late Old English hwearf "shore, bank where ships can tie up," earlier "dam, embankment," from Proto-Germanic *hwarfaz (source also of Middle Low German werf "mole, dam, wharf," German Werft "shipyard, dockyard"); related to Old English hwearfian "to turn," perhaps in a sense implying "busy activity," from PIE root *kwerp- "to turn, revolve" (source also of Old Norse hverfa "to turn round," German werben "to enlist, solicit, court, woo," Gothic hvairban "to wander," Greek karpos "wrist," Sanskrit surpam "winnowing fan"). Wharf rat is from 1812 as "type of rat common on ships and docks;" extended sense "person who hangs around docks" is recorded from 1836.
"action of blocking or stopping up," especially, in medicine, "constipation," 1590s, from Latin obstipationem (nominative obstipatio), noun of action from past-participle stem of *obstipare "action of blocking or stopping up," from ob "in front of; in the way of" (see ob-) + stipare "to press together, to pack" (see stiff (adj.)).
Old English stif "rigid, inflexible," from Proto-Germanic *stifaz "inflexible" (source also of Dutch stijf, Old High German stif, German steif "stiff;" Old Norse stifla "choke"), from PIE *stipos-, from root *steip- "press together, pack, cram" (source also of Sanskrit styayate "coagulates," stima "slow;" Greek stia, stion "small stone," steibo "press together;" Latin stipare "pack down, press," stipes "post, tree trunk;" Lithuanian stipti "to stiffen, grow rigid," stiprus "strong;" Old Church Slavonic stena "wall"). Of battles and competitions, from mid-13c.; of liquor, from 1813. To keep a stiff upper lip is attested from 1815. Related: Stiffly.
1590s, from French tarot (16c.), from Old Italian tarocchi (singular tarocco), a word of unknown origin, perhaps from Arabic taraha "he rejected, put aside." Originally an everyday game deck in much of Europe (though not in Britain), their occult and fortune-telling use seems to date from late 18c. and became popular in England 20c. Tarot games seem to have originated among aristocrats in northern Italy in early 15c. By early 16c. tarocchi had emerged in Italian as the name of the special cards, and by extension the whole pack; whence the French word, German Tarock, etc. The tarots are thus, strictly speaking, the 22 figured cards added to the 56-card suits pack.
"a rodent mammal" 1835 (as an adjective 1833), from Modern Latin Rodentia, the order name, from Latin rodentem (nominative rodens), "the gnawers," present participle of rodere "to gnaw, eat away," which is of uncertain etymology, possibly is from an extended form of PIE root *red- "to scrape, scratch, gnaw." Uncertain connection to Old English rætt (see rat (n.)). They are characterized by having no canine teeth and strong incisors.
"put into a bag, pack in a sack" for preservation or transport, hence also generally "to lay up, hoard;" c. 1300, from sack (n.1). Related: Sacked; sacking. The sacked friars (c. 1400, sakked freres) were a mendicant order noted for wearing sackcloth; they appeared in England mid-13c.
