Selected source glosses provide context, not a complete modern definition inventory

First attested as an underworld term for an apparatus for creating counterfeit coins, then the coins themselves. Later, the word was applied to anything of poor quality. The newest use to mean useless is probably from the slang of computer hackers. The origin is unknown, but there are at least two theories that try to trace its origin: * From Hausa boko (“to fake”). Since bogus first appeared in the United States, it may be possible that its ancestor was brought there on a slave ship. * From criminal slang as a short form of tantrabogus, a 19th-century slang term for a menacing object, making some believe that bogus might be linked to bogy or bogey (see bogeyman). In this sense, Bogus might be related to Bogle – a traditional trickster from the Scottish Borders, noted for achieving acts of household trickery; confusing, but not usually damaging.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
