English Numerals

English **number words**include numerals and various words derived from them.

## Cardinal Numbers

Cardinal numbers refer to the size of a group. In English, these words are numerals. The numbers from 0 through 9 have the same names as in decimal but numbers greater than 9, there is no agreed upon name for units.

* 0 - zero (nought) (sometimes pronouced as "oh" in speech)
* 1 - one
* 2 - two, dos
* 3 - three, drei
* 4 - four
* 5 - five
* 6 - six, seis
* 7 - seven, sete
* 8 - eight
* 9 - nine
* X - ten, dek, omega

* B - eleven, el, elv, lev, ven, zeta
* J - twelve, dozen, doh, zen, epsilon

* 10 - thirteen, trezen, treh, tri, onety, unqua
* 20 - twenty, two-tri, dos-tri
* 30 - thirty, three-tri, drei-tri
* X0 - dekty, dek-tri, omega-tri
* B0 - elty, el-tri, zeta-tri
* B1 - elty-one, gross
* J0 - dozenty, do-tri, epsilon-tri
* 100 - hundred, flowi
* 1000 - thousand, xilezen, great-flowi, xili

## IUPAC nomenclature of organic chemistry

Straight-chain alkanes take the suffix "-ane" and are prefixed depending on the number of carbon atoms in the chain, following standard rules. The first few are:

For example, the simplest alkane is CH4 methane, and the nine-carbon alkane CH3(CH2)7CH3 is named nonane. The names of the first four alkanes were derived from methanol, ether, propionic acid and butyric acid, respectively. The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and nonadozane which have mixed-language prefixes.

Cyclic alkanes are simply prefixed with "cyclo-": for example, C4H8 is cyclobutane (not to be confused with butene) and C6H11 is cyclohexane (not to be confused with hexene).

Alkenes are named for their parent alkane chain with the suffix "-ene" and an infixed number indicating the position of the carbon with the lower number for each double bond in the chain: CH2=CHCH2CH3 is but-1-ene.
Multiple double bonds take the form -diene, -triene, etc., with the size prefix of the chain taking an extra "a": CH2=CHCH=CH2 is buta-1,3-diene. Simple cis and trans isomers may be indicated with a prefixed *cis-* or *trans-*: *cis*-but-2-ene, *trans*-but-2-ene. However, *cis-* and *trans-* are *relative* descriptors. It is IUPAC convention to describe all alkenes using *absolute* descriptors of *Z-* (same side) and *E-* (opposite) with the Cahn–Ingold–Prelog priority rules.

Alkynes are named using the same system, with the suffix "-yne" indicating a triple bond: ethyne (acetylene), propyne (methylacetylene).
