"Fuck you/V sign" This folk etymology centers on archers who had their middle fingers removed in medieval times to keep them from properly aiming their arrows. English longbow archers caught by the enemy at Agincourt supposedly would have had their bow fingers amputated, since at that time the longbow was a devastating weapon and gave a great tactical advantage to the English. The unaffected archers could taunt the enemy by raising their index and middle fingers to show they were still intact and that the archers could still effectively "pluck yew". However, this story is untrue. (See the origins of the V sign for further discussion.)
The word "picnic" did not originate as an abbreviation of "pick a nigger", a phrase falsely claimed to have been used by white families at community lynchings in the 19th century. "Picnic" comes from 17th-century Frenchpiquenique, which is of uncertain origin.
The use of "buck" to mean "dollar" did not originate from a practice of referring to African slaves as "bucks" (male deer) when trading. "Buck" was originally short for "buckskin", as buckskins were used in trade.
A "crowbar" is not so named for its use by Black menial workers. The name comes from the forked end of a crowbar, which resembles a crow's foot.
The cacophemism "wog", for a foreigner or coloured person, is sometimes believed to be an acronym for "wily Oriental gentleman". It is more likely to be a shortening of "golliwog".
"Golf" did not originate as an acronym of "Gentlemen Only, Ladies Forbidden". The word's true origin is unknown, but it existed in the Middle Scots period.
Some falsely believe that the word coma originates from Cessation Of Motor Activity. Although this describes—fairly accurately—the condition of coma, this is not the true derivation.
The word news has been claimed to be an acronym of the four cardinal directions (North, East, West, and South). However, old spellings of the word varied widely (e.g., newesse, newis, nevis, neus, newys, niewes, newis, nues, etc.). Additionally, an identical term exists in French, "les nouvelles", which translates as the plural of "the new". The word "news" is simply a plural form of new.
Tips did not gain their name from the acronym "To Insure Prompt Service". The word originated in Shelta in the 17th century and is of uncertain origin.
There is no evidence that posh was ever an acronym for wealthy British passengers getting "Port Out, Starboard Home" cabins on ocean liners to India, in order to get ocean breeze.
"420" did not originate as the Los Angelespolice or penal code for marijuana use. Police Code 420 is "juvenile disturbance", and Penal Code 420 defines the prevention, hindrance, or obstruction of legal "entry, settlement, or residence" on "any tract of public land" as a misdemeanor. The use of "420" started in 1971 at San Rafael High School, where it indicated the time 4:20 PM, when a group of students would go to smoke cannabis under the statue of Louis Pasteur. Some LA police codes that do relate to illegal drugs include 10-50 ("under influence of drugs"), 966 ("drug deal"), 11300 ("narcotics"), and 23105 ("driver under narcotics").
The idiom "rule of thumb" is not, as some have suggested, derived from a medieval constraint on the thickness of an object with which one might beat one's wife. No such law has been uncovered.
The word "isle" is not short for "island", nor is the word "island" an extension of "isle". "Isle" comes ultimately from Latinīnsula, meaning "island"; "island" comes ultimately from Old Englishīegland, also meaning "island"; the words are unrelated.
It is not the case that the term nasty was derived from the surname of Thomas Nast as a reference to his biting, vitriolic cartoons. The word may be related to the Dutch word nestig, or "dirty". It predates Nast by several centuries, appearing in the most famous sentence of Thomas Hobbes's Leviathan, that in the state of nature, the life of man is "solitary, poor, nasty, brutish, and short." That work was published in 1651, whereas Nast was born in 1840.
A popular story claims that the conqueror Jean de Bethencourt was so impressed with the peaceful nature of the inhabitants of the island Lanzarote that he broke his lance in half, with the island's name thus being derived from lanza rota (broken lance). However, this story is unlikely, and the island is probably named after the 13th century trader Lancelotto Malocello.
"Hiccough", an alternate spelling still encountered for hiccup, originates in an assumption that the second syllable was originally cough. The word is in fact onomatopoeic in origin.
"Welsh Rarebit" has been claimed to be the original spelling of the savoury dish 'Welsh rabbit'. Both forms now have currency, though the form with rabbit is in fact the original. Furthermore, the word 'Welsh' in this context was used by the English as a slur, meaning foreign, as with French letter, and does not indicate that the dish originated in Wales.
"scissors": the spelling reflects a belief that the word comes from Latin scindere (to tear); in fact the word is derived from Old French cisors (current French ciseaux), which comes from Latin caedere (to cut).
"innocent": often wrongly believed to have the original meaning of "not knowing", as if it came from Latin noscere (to know); in fact it comes from nocere (to harm), so the primary sense is "harmless".
"marmalade": there is an apocryphal story that Mary, Queen of Scots, ate it when she had a headache, and that the name is derived from her maids' whisper of "Marie est malade" (Mary is ill). In fact it is derived from Portuguese marmelo, meaning quince, and then expanded from quince jam to other fruit preserves. It is found in English-language sources written before Mary was even born.
"sirloin": an equally apocryphal story features an English king (usually identified as Charles II) conferring knighthood on a beef roast, saying "Rise, Sir Loin!" The name merely means the top of the loin (from French sur, on or above).
"adamant": often believed to come from Latin adamare, meaning to love to excess. In fact derived from Greek ἀδάμας, meaning indomitable. There was a further confusion about whether the substance referred to is diamond or lodestone.
"pumpernickel" is said to have been given the name by a French man (sometimes Napoleon) referring to his horse, Nicole—"Il étoit bon pour Nicole" ("It's good enough for Nicole"), or "C'est un Pomme pour Nicole" ("it's an apple for Nicole"). Some dictionaries claim a derivation from the German vernacular Pumpern (fart) and "Nick" (demon or devil) though others disagree.
"Sword" did not come from "God's word" ('sword) as a minced oath (in the same way that 'sblood is "God's blood"). This confusion could come from the fact that God's word in the bible is said to be "sharper than any two-edged sword", and would hence relate to the Christian origins of many English words.
"Woman" did not originate from "woven from man". It came from the old English "wiffmann", meaning "female person". "Wermann", the word for a male, was shortened to "mann" (now it is spelled "man"), and "wiffman" was developed into "woman."
"Sincere" does not originate from Latin sine cera, without wax.
