What do the “twen-” and “-ty” in twenty mean exactly?

Think about what you take for granted. Do you ever wonder why “America” is named after Amerigo Vespucci? Why we call green green? The same goes for twenty.

Twenty is the natural number sandwiched between nineteen and twenty-one. The word comes from the Old English twegen, which means “two,” and the Old English suffix –tig, which means “group of ten.” The suffix –ty expresses numerals that are multiples of ten: twenty, forty, sixty, and so on. A score is a group or set of twenty. For example: “Four score and seven years ago, our fathers . . .”

In the United States, 20/20 indicates normal vision at twenty feet. People with 20/20 vision are said to have “perfect” sight. Hawks and some other birds have vision as sharp as 20/2. First recorded in 1962, the expression twenty-twenty hindsight is used to express knowledge that was gained after the fact. The expression now has variations and is often used to convey regret. For example: “We should never have taken our Caribbean vacation in June. We spent the whole trip boarded up in our hotel waiting for the hurricane to pass. Hindsight is twenty-twenty.” The meaning of the word hindsight, “seeing what has happened,” is from 1883, and was probably formed on the model of foresight. A little-known Greek myth personifies Prometheus and his brother Epimetheus as foresight and hindsight respectively. (That may help explain the fact that Epimetheus was the husband of Pandora.) The word twenty also comes into play in a popular party and road game that is over 200 years old: twenty questions.

Here’s a question: Who is July named for, and what was the month’s earlier name? (Click here for the answer.) Feel free to ask as many questions as you like in the comments below.

    I believe the word ‘twin’ is also derived from this Old English word, because well, ‘two’ babies, instead of one.

    America is NOT named after Amerigo Vespucci. It is named after the Welshman Richard Americ.

    Allan said “It actually seems unlikely that the US is named after Vespucci.” While that’s technically correct, the implications of the statement bothers me so much I’m posting this even if it doesn’t have a chance of being seen by you.

    The United States of America was NOT named after any person. The name for the continents came first; the U.S. didn’t even exist until 1776. In addition, there’s more than one country even in North America! Have we gotten so arrogant as to assume that the U.S. came first and covers the entire Western Hemisphere?

    The Reason WHy America is named after Vespucci is because he supposedly read the map wrongly and signed where The Title of the land was supposed to go.

    Viki :- Eleven and twelve are useful when you count in base twelve. You count up using the knuckles of your hand. When you get to Twelve you stick the thumb up and then start on the other hand. That was probable enough way back for tallying sheep, chickens etc. and you couldn’t handle paper with wet hands.

    The Library of Congress is still sticking with the Amerigo Vespucci story – and recently paid something like $10M for the only known copy of the Waldseemüller map using the term “America” for the first time (1507).

    Matt who often ponders word origins might want to subscribe to Merriam-Webster’s Word of the Day.

    Chelsea asked: When did people start using last names? Napoleon Bonaparte (15 August 1769 – 5 May 1821) started it for most of Europe when he insisted that all citizens of countries he conquered had family (sur) names for census purposes; people were allowed to select their own and many did according to profession (Taylor/tailor/schnieder), Smith (gold, silver, black) or location (Feld/field, Valle), or other attribute.

    @Viki. If your on dictionary, why not look it up yourself?

    “Word History : The decimal system of counting is well established in the English names for numbers. Both the suffix -teen (as in fourteen ) and the suffix -ty (as in forty ) are related to the word ten. But what about the anomalous eleven and twelve? Why do we not say oneteen, twoteen along the same pattern as thirteen, fourteen, fifteen? Eleven in Old English is endleofan, and related forms in the various Germanic languages point back to an original Germanic *ainlif, “eleven.” *Ainlif is composed of *ain-, “one,” the same as our one, and the suffix *-lif from the Germanic root *lib-, “to adhere, remain, remain left over.” Thus, eleven is literally “one-left” (over, that is, past ten), and twelve is “two-left” (over past ten).”

    I’ve always kinda wondered about the origins of the numbers eleven and twelve. Does anyone know?

    It seems logical that thirteen is similar to “three and ten,” fourteen is similar to “four and ten,” and twenty-one is obviously “twenty and one,” and so on. But where the heck did eleven and twelve come from?

    The best way to be able to easily figure out the meanings or definitions of words as well as to be able to make up words that actually make sense is to learn Greek and latin origins of english words as well as just exposing yourself to alot of various verbose vocabulary.

    Or maybe “The Devil’s Dictionary” by Ambrose Bierse (SP??) for a fun look at how words might have been defined.

    It actually seems unlikely that the US is named after Vespucci. First names are traditionally only used when naming a place after a member of the nobility (e.g. Prince Edward Island, Alberta, Victoria). Vespucci was not a noble. For non-nobles, last names are used (e.g. Bering Strait, St Lawrence River, Baie de Champlain).
