Word Origin & History

bug
"insect," 1620s (earliest reference is to bedbugs), probably from M.E. bugge "something frightening, scarecrow" (late 14c.), a meaning obsolete except in bugbear (1570s) and bugaboo (q.v.); probably connected with Scot. bogill "goblin, bugbear,"
or obsolete Welsh bwg "ghost, goblin" (cf. Welsh bwgwl "threat," earlier "fear"). Cf. also bogey (1) and Ger. bögge, böggel-mann "goblin." Perhaps influenced in meaning by O.E. -budda used in compounds for "beetle" (cf. Low Ger. budde "louse, grub," M.L.G. buddech "thick, swollen"). Meaning "defect in a machine" (1889) may have been coined c.1878 by Thomas Edison (perhaps with the notion of an insect getting into the works). Meaning "person obsessed by an idea" (e.g. firebug) is from 1841. Sense of "microbe, germ" is from 1919. Bugs "crazy" is from c.1900.

bug
"to bulge," 1870s, perhaps from a humorous or dialect mispronunciation of bulge. The verb "to annoy, irritate" is first attested 1949, probably in allusion to insect pests, from bug (n.). Sense of "equip with a concealed microphone" is from 1919. Related: Bugged; bugging. Phrase
bug off is 1950s, perhaps from bugger off, which is chiefly British (by 1920s) but was picked up in U.S. Air Force slang in the Korean War.

bug   (bŭg)  Pronunciation Key 
  1. An insect belonging to the suborder Heteroptera. See more at true bug.

  2. An insect, spider, or similar organism. Not in scientific use.


Our Living Language  : The word bug is often used to refer to tiny creatures that crawl along, such as insects and even small animals that are not insects, such as spiders and millipedes. But for scientists the word has a much narrower meaning. In the strictest terms bugs are those insects that have mouthparts adapted for piercing and sucking. The mouthparts of these bugs are contained in a beak-shaped structure. Thus scientists would classify a louse but not a beetle or a cockroach as a bug. In fact, scientists often call lice and their relatives true bugs to distinguish them better from what everyone else calls "bugs."

bug definition


A generic term that describes a malfunction of undetermined origin in a computer or other electronic device.

Note: The term originated in the 1940s when the examination of a large computer revealed that an actual insect had landed on one of the circuits, shorting it out and shutting the machine down.
