what is the derivation of the word come eleven and twelve don't fit the teen convetion shared by 13-19? Kingturtle 23:50, 29 Sep 2003 (UTC)

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). Evil saltine 23:53, 29 Sep 2003 (UTC)

Could this not be put into the article? doktorb wordsdeeds 10:44, 27 October 2006 (UTC)

Divisibility Test[edit]

I think that the base 10 divisibility test for 11 is worth mentioning here, so I added it, but I wonder if my explanation of it is simple and easy to understand. If anyone here can explain it better, I encourage them to edit the divisibility paragraph. PrimeFan 21:41, 12 Mar 2004 (UTC)

        • Count by tens or count by twelves ****

Why do we have 1 left (eleven) and 2 left (twelve) instead ainteen and twateen? Consider the number of inches in a foot (12) and the number of items that compose a unit for shopkeepers (a dozen = 12 or a half dozen = 6) the number of items in a gross (12 * 12) and finally the fact that early on there was an eleventy (11 * 10) and a twelfty (12 * 10) in the language--tho that disappeared early. The number 12 was used as an alternate base for counting and measurement by various folk in Northern Europe. It may be that the ten based numbers and the twelve based numbers were used in different ways--who knows? What does seem likely is that when people began to count units of 12 they had to remember that there were two more numbers per unit than they had fingers. As for 11, I speculate that it was merely the number between the two bases, twelve and ten. Greycats 30 August 2005

Tomatoes are delicious[edit]

One of the standard examples of patent nonsense is an article consisting of the phrase

Tomatoes are delicious! 11!

or something like that. Does anyone have any idea what the "11" means here, if anything? Is it leet, for example? --Trovatore 18:59, 19 November 2005 (UTC)

It looks suspiciously like leet, yes, in particular over-exclamation. If this was the case I wouldn't expect a space among the !s and 1s, though. 4pq1injbok 19:28, 19 November 2005 (UTC)
Thanks, that looks like the answer. I think the spaces weren't there in the original. --Trovatore 19:34, 19 November 2005 (UTC)
This is old now, but it is because the author has accidentally? purposefully? taken their finger off the SHIFT key. I have seen people go to the extent of writing like this!!!11!eleven! ~~ THE DARK LORD TROMBONATOR (((¶))) 10:55, 19 July 2007 (UTC)


Is the F11-function key remark really necessary. One might as well add the F11 function of all 40+ programs installed on my PC. I don't think this is the right place to mention this.

Besides your Web browser and Microsoft Excel, I seriously doubt that the 40+ programs on your computer have any assignments for the F11 key, much less diverse assignments. But if they do have diverse assignments, can you notice any similarities? PrimeFan 20:52, 11 February 2006 (UTC)

Relation to 9/11 attack[edit]

An anonymous user added the following to the article. Rather than simply deleting it, I decided to integrate it into the article. PrimeFan 20:48, 11 February 2006 (UTC)

1) New York City has 11 letters

2) Afghanistan has 11 letters.

3) Ramsin Yuseb (The terrorist who threatened to destroy the Twin Towers in 1993) has 11 letters.

4) George W Bush has 11 letters.

1) New York is the 11th state.

2)The first plane crashing against the Twin Towers was flightnumber11.

3) Flight 11 was carrying 92 passengers. 9 + 2 = 11

4) Flight 77 which also hit Twin Towers, was carrying 65passengers.6+5 = 11

5) The tragedy was on September 11, or 9/11 as it is now known.9 +1+ 1 =11

6) The date is equal to the US emergency services telephonenumber911. 9 + 1 + 1 = 11.

1) The total number of victims inside all the hi-jacked planeswas254. 2 + 5 + 4 = 11.

2) September 11 is day number 254 of the calendar year. Again 2+ 5+ 4= 11.

3) The >>>Madrid bombing took place on 3/11/2004. 3 + 1 + 1 + 2 + 4 =11.

4) The tragedy of Madrid happened 911 days after the TwinTowersincident.

      • The statement below is false.

That verse is number 9.11 of the Quran.


anon contributions[edit] (talk · contribs) has been making additions of factoids about this number in various bases, which I don't think belong here. He seems also to accidentally remove other factoids in the article. Any comments? — Arthur Rubin | (talk) 17:22, 23 June 2007 (UTC)


Is there a proof for the diviibility test? I understand, but would like a fuller explanation of it's origin if possible.Beligaronia 04:09, 1 July 2007 (UTC)

Fool's number[edit]

I added that 11 is the 'fool's number'. Is this just a Dutch thing? If so, I should have added that. I am starting to wonder because I can't find anything about it googling in English. I haven't tried any other languages yet. DirkvdM (talk) 08:20, 11 November 2008 (UTC)

Counting on human fingers[edit]

"Eleven is the first number which cannot be counted with a human's eight fingers and two thumbs additively."

This is just wrong. In some societies (see people count from one using no fingers up to twelve. — Preceding unsigned comment added by (talk) 13:11, 12 November 2011 (UTC)
