A humbug is a person or object that behaves in a deceptive or dishonest way, often as a hoax or in jest. The term was first described in 1751 as student slang, and recorded in 1840 as a "nautical phrase". It is now also often used as an exclamation to describe something as hypocritical nonsense or gibberish. When referring to a person, a humbug means a fraud or impostor, implying an element of unjustified publicity and spectacle. In modern usage, the word is most associated with the character Ebenezer Scrooge, created by Charles Dickens in his 1843 novella A Christmas Carol. His famous reference to Christmas, "Bah! Humbug!", declaring Christmas to be a fraud, is commonly used in stage and screen versions and also appeared frequently in the original book. The word is also prominently used in the 1900 book The Wizard of Oz, in which the Scarecrow refers to the Wizard as a humbug, and the Wizard agrees. Alternative root based on Millers Fly Leaves: During continental war in the 1700s many false reports and lying bulletins were fabricated in Hamburg, Germany. The phrase ‘this is Hamburg’ was in Britain shortened to ‘Humbugs’. This then is a statement of disbelief I.e. Bah Humbug. If one says ‘you had that from Hamburg’, it is an expression of incredulity. We don’t know who Miller was. This explanation was taken from A Treatise on humbug by a Manchester Man, volume 1, 1866. Another use of the word was by John Collins Warren, a Harvard Medical School professor who worked at Massachusetts General Hospital. Dr. Warren performed the first public operation with the use of ether anesthesia, administered by William Thomas Green Morton, a dentist. To the stunned audience at the Massachusetts General Hospital, Warren declared, "Gentlemen, this is no humbug."
Etymology
The oldest known written uses of the word are in the book The Student, ii. 41, where it is called "a word very much in vogue with the people of taste and fashion", and in Ferdinando Killigrew's The Universal Jester, subtitled "a choice collection of many conceits... bon-mots and humbugs" from 1754; as mentioned in Encyclopædia Britannica from 1911, which further refers to the New English Dictionary. There are many theories as to the origin of the term, none of which has been proven:
Charles Godfrey Leland mentions the idea that the word could be derived from the Norse word hum, meaning 'night' or 'shadow', and the word bugges, a variant of bogey, meaning 'apparitions'. The Norse word hum mentioned, or hume, actually means 'dark air' in Old Norwegian. From the other Scandinavian languages based on Old Norse, there is húm in Icelandic which means 'twilight', hómi in Faeroese which means 'unclear', and humi in Old Swedish which means 'dark suspicion', documented back to 1541. From this word is also derived the Swedish verb hymla, still in use, which means 'to conceal, hide, not commit to the truth'.
According to the Dictionary of the Vulgar Tongue by Francis Grose, 1731–1791, to hum in English indeed originally meant 'to deceive'. To combine this early medieval Scandinavian word with bugges from the English Bible of a later date may seem far-fetched. The word bug is derived from the Middle EnglishBugge which is in turn a cognate of the German word bögge and possibly the Norwegian dialect word bugge meaning "important man". The Welsh bwg could also be connected, and was thought in the past to be the origin of the English term however more recent studies indicate that it is a borrowing from the much older Middle English word. Also, with bug meaning ghost or goblin, the use of the term applies in Dickens' novel about the Christmas ghosts. In Etym. Diet. of 1898, Walter Skeat also proposed a similar theory, although using contemporary versions of the words, where hum meant to murmur applause, and bug being a spectre.
It could also come from the Italianuomo bugiardo, which literally means 'lying man'. There was considerable Italian influence on English at the time.
Uim-bog is supposed to mean 'soft copper' in Irish, worthless money, but there is no evidence of a clear connection to the term.
The 1911 Encyclopædia Britannica also suggests that it is a form of "Hamburg", where false coins were minted and shipped to England during the Napoleonic wars, which is inaccurate as the Napoleonic wars occurred 50 years after the word first appeared in print.
A modern conception is that it actually refers to a humming bug—i.e. something small and inconsequential, such as a cricket, that makes a lot of noise. In Norton Juster's novel The Phantom Tollbooth, there is a large beetle-like insect known as the Humbug, who is hardly ever right about anything.
The word has been used outside anglophone countries for well over a century. For instance, in Germany it has been known since the 1830s, in Sweden since at least 1862, in France since at least 1875, in Hungary, and in Finland.
