(Ed: for convenience of typing T and E are used here for ten and eleven)
I had never seen a *good* base 12 number system. Thus, I created this one (which hopefully is).
I have adopted a variant of the symbols for nine plus one and nine plus two as supported by the dozenal society of Great Britain.
Where I have deviated from normal numbers where you might not expect me to (eg. Nine = "en") I have done so for practical reasons only.
I have tried to create reasonable and distinct
sounding names, that are easy to say.
The "teens" are accommodated by the suffix -twe, and the dozens beyond that by the suffix -do.
Occasionally, you may note "blips" in the spelling
such as ad + twe = addwe. This is a simple matter of
assimilation, that which occurs so that adjoining
consonants move to the same point of articulation etc
(for ease of speech). Thus, sometimes "-do" becomes
Occasionally, some vowels may also be missed (eg. One + twe = ontwe). This, too, is for pronounciation and language reasons. Sometimes, though, I have not done this when by pattern I should have - this is so as to indicate pronounciation.
|7||Sept||(pronounced "set", like the French number for seven)|
|E||Elf||(German for eleven)|
|12||Tutwe||(pr. Tut-wee or too-tway)|
|13||Thretwe||(pr. Thret-wee, thret-way)|
|15||Fiftwe||(sometimes I pronounce this "fye-wee")|
|16||Sixtwe||(I have come to pronounce this as "sight-wee")|
|1T||Dentwe||(sometimes denetwe - "den-et-way")|
|1E||Elftwe||(I usually do not pronounce the t here)|
|30||Thredo||(I often pronounce this as "thray-doh")|
|70||Septto/Seddo||(Pr. "Sept-toh" or "set-toh" or "see-doh")|
The present year, (2003ad) / 11TE ad = Ontwe Denedo elf (or) One grand, One gross and denedo-elf
As far as higher powers go, it depends really on whether you are using the one thousand million = 1 billion system, or the one million million = 1 billion system. I will not impose, but will say that the higher names are:
|1 grand milliad (or) 1 milliad milliad = 1 billiad|
|1 milliad milliad (or) 1 milliad milliad milliad = 1 trilliad|
|1 grand^6 (or) 1 milliad^6 = 1 hexiad|
|1 grand^*10 (or) 1 milliad^*10 = 1 uniad|
I hope you got that. I shall rephrase, in case you did not:
One dozenal "million" = 1 milliad
One dozenal "billion" = 1 billiad
One dozenal "trillion" = 1 trilliad
One trilliad times by one trilliad = 1 hexiad
One hexiad times one hexiad = 1 uniad.
The values are different, obviously, due to the two different number systems used worldwide.
Even higher numbers are formed in the usual way. That is, the numbers + iad (illion in decimal). So, Grossiad, for instance.
I reject the often-heard "-dek", amongst others, as I view them as aesthetically displeasing. If a number has to be changed, the goal is to make it easy to say, distinct, possibly vaguely English, and aesthetically pleasing (at least not distasteful).
The symbols I use for dene and elf are borrowed from Arabic, hence their strange style. These are as close as word can come to the *actual* dozenal symbols for these. Though, these symbols are almost exactly right, just move them up onto the line, and Romanise their curves. Dene is like a cursive t, and elf is a back-to-front *rounded* three.
I believe this to be a full and useful system of dozenal numeration. Obviously it is not "final", in as much as pronounciation changes, new ways are found to distinguish things, etc. (All comments welcome!).
