Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English loupe; akin to Middle Dutch lūpen, to lie in wait, peer.]

from The American Heritage® Dictionary of the English Language, 4th Edition

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Middle English loupe ("noose, loop"), earlier lowp-knot ("loop-knot"), of North Germanic origin, ultimately from Old Norse hlaup ("a run", literally, "a leap"), used in the sense of a "running knot". Compare Swedish löp-knut ("loop-knot"), Danish løb-knude ("a running knot"), Danish løb ("a course"). More at leap.

Examples

  • The law concerning the generation of electromotive force and current in a conductor that is cutting through lines of magnetic force, may be stated in another way, when the conductor is bent into the form of a loop, as in the case under consideration: Thus, _if the number of lines of force which pass through a conducting loop be varied, electromotive forces will be generated in the loop_.
