early 13c., from Anglo-French bascat; of obscure origin despite much speculation. On one theory, it is from Latin bascauda "kettle, table-vessel," said by the Roman poet Martial to be from Celtic British and perhaps cognate with Latin fascis "bundle, faggot," in which case it probably originally meant "wicker basket." But OED frowns on this, and there is no evidence of such a word in Celtic unless later words in Irish and Welsh, sometimes counted as borrowings from English, are original. As "a goal in the game of basketball," 1892; as "a score in basketball," by 1898.
a name of pointed instruments of various kinds, and also other noun senses, in most cases from pick (v.) but in some perhaps with some influence of pick (n.1). Meaning "a blow with a pointed instrument" is from mid-15c; the sense in toothpick is from late 15c. The meaning "plectrum for a guitar, lute, etc." is from 1895. As a type of basketball block, from 1951. The meaning "right of selection, first choice" is by 1772, hence "choicest part or example" (by 1858). Meaning "instrument for picking locks" is by 1890.
1580s, "let fall in drops or bits;" 1590s (intransitive) "fall in drops or small particles," frequentative of obsolete verb drib (1520s), a variant of drip (v.). The sports sense "give the ball a slight shove or bounce" first was used in soccer (1863), the basketball sense is by 1892 (implied in dribbling). Related: Dribbled. As a noun from 1670s.
1919, "to dip (something) into a beverage or other liquid," American English, from Pennsylvania German dunke "to dip," from Middle High German dunken, from Old High German dunkon, thunkon "to soak," from PIE root *teng- "to soak" (see tincture). The basketball sense "jump up and push (the ball) down through the basket" is recorded by 1935 as a verb (implied in dunking), 1967 as a noun (earlier dunk shot, 1950). Related: Dunked.
