early 15c., "one of a series of rings or loops which form a chain; section of a cord," probably from Old Norse *hlenkr or a similar Scandinavian source (cf.

German lenken "to bend, turn, lead," gelenk "articulation, joint, link," Old English hlencan (plural) "armor"), from PIE root *kleng- "to bend, turn." Missing link between man and apes dates to 1880.
"torch," 1520s, of uncertain origin, possibly from Medieval Latin linchinus, from lichinus "wick," from Greek lykhnos "portable light, lamp."
