"Indeed," George Washington wrote in his diary in 1785, "some kind of fly, or bug, had begun to prey upon the leaves before I left home." The father of our country was not the father of bug. When Washington wrote that entry, Englishmen had been referring to insects as bugs for more than a century, and we Americans had already created Lightning Bug (1778). But the English were soon to get rid of the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

We got bug in our ears in other ways too. The American bug could also be a person, an enthusiast or fanatic, as the Congressional Globe records in 1841: "Mr. Alford of Georgia warned the 'tariff bugs' of the South that...he would read them out of church." And although fan became the usual term, sports enthusiasts were racing bugs (1908), baseball bugs (1911), and the like. And a bug could be just plain insane (1884), confined to a bughouse (1899).

Or the bug could be a small machine or object: a telegraph key (1929); a clip used by a card sharp to hold cards under the table (1883); even a car, the small, bug-shaped, trademarked Volkswagen beetle (1960). The bug could also be a burglar alarm (1926), from which comes the expression to bug, that is, originally "to install an alarm," now a surveillance device like a hidden microphone. Since the 1840s to bug has long meant "to cheat," and since the 1940s it has been annoying.

We also know the bug as a flaw in a computer program or other design. That meaning traces back long before computers to the laboratory of inventor Thomas Edison. In 1878 he explained bugs as "little faults and difficulties" that require "months of anxious watching, study and labor" to overcome in developing a successful product. In 1889 it was recorded that Edison "had been up the two previous nights discovering 'a bug' in his phonograph."

Don't bug us for more definitions, or we'd have to fill the whole book with bugs.
