lock (v.) Look up lock at Dictionary.com
c. 1300, "to fasten with a lock, shut or confine with a lock." The sense is narrowed from that of Old English lucan "to lock, to close" (class II strong verb; past tense leac, past participle locen), from the same verbal root that yielded lock (n.1). The form is from the noun (perhaps reinforced by Old Norse loka); the old original strong verb survived as dialectal louk, and the strong past participle locken lingered a while, as in Middle English loken love "hidden love, clandestine love" (early 14c.).

The Old English verb is cognate with Old Frisian luka "to close," Old Saxon lukan, Old High German luhhan, Old Norse luka, Gothic galukan.

Ordinary mechanical locks work by means of an internal bolt or bar which slides and catches in an opening made to receive it. "The great diversity of meaning in the Teut. words seems to indicate two or more independent but formally identical substantival formations from the root" [OED]. The Old English sense "barrier, enclosure" led to the specific meaning "barrier on a stream or canal" (c. 1300), and the more specific sense "gate and sluice system on a water channel used as a means of raising and lowering boats" (1570s). From 1540s as "a fastening together," hence "a grappling in wrestling" (c. 1600).

loco-foco (n.) Look up loco-foco at Dictionary.com
also locofoco, American English, said to date from 1834 in the sense "self-igniting cigar or friction match," of obscure origin. The first element is apparently a misapprehension of the loco- in locomotive ("a word just then becoming familiar" [Century Dictionary]) as "self-, self-moving-." The second element is perhaps a jingling reduplication of this, or somehow from Spanish fuego "fire."

Better remembered, if at all, as a political term: During a heated Democratic party meeting in Tammany Hall c. 1835, the opposition doused the gaslights to break it up, and the radical delegates used loco-foco matches to relight them. When it was publicized, the name loco-foco entered U.S. political jargon (by 1837) and down to the Civil War was applied, usually disparagingly, to a radical faction of the Democratic Party (but by the Whigs to all Democrats).
