  NationMaster - Encyclopedia: Greek numerical prefixes
Chilia- (pronounced KIL-ee-uh) is the Greek numerical prefix for 1000.
Numerical prefixes are usually derived from the words for numbers in various languages, most commonly Greek and Latin, although this is not necessarily the case.
The SI prefix was adopted by France in 1795 and internationally by 1960.

 Polyhedra Names
Many names are constructed from Greek prefixes for the number of sides and the root -hedron meaning faces (literally meaning "seat").
Numerical modifiers like pentagonal or hexagonal can refer not only to the shape of individual faces, but also to a base polygon from which certain infinite series of special polyhedra can be constructed.
The rhombi prefix indicates that some of the faces (12 squares in the first two cases, 30 squares in the last two) are in the planes of the rhombic dodecahedron (in the first two cases) and the rhombic triacontahedron (in the last two cases).

 Numerical Terms
Numerical terms are used in chemical names for indicating a number of identical structural units in a compound.
However, the multiplying prefixes "bis-", "tris-", etc., are used instead of "di-", "tri-", etc., when the use of the latter would result in a potential ambiguity; for example, tris(decyl) is used to describe three decyl substituents because tridecyl is the name for a thirteen carbon acyclic substituent.
According to Greek etymology, the ending for hundreds should be "-acosia-" which would lead to terms such as diacosia- for 200, triacosia- for 300, etc. However, these terms happen to be very similar to docosa- for 22, tricosa- for 23, etc. This is why the ending "-cta-", taken from hecta-, was proposed (ref.

 Lambda Introduction
The additive prefix "hydro" indicates nonstandard valences of heteroatoms in heterocycles by describing the addition of hydrogen atoms, which may be later substituted just as those already implied by the name of the heterocycle.
The subtractive prefix "dehydro" is used occasionally to indicate nonstandard valence of heteroatoms in heterocycles by describing the removal of hydrogen atoms implied by the name of the heterocycle.
The use of arabic numerals as superscripts to italicized element symbols was suggested, but not well received because italicized element symbols with numerical superscripts are used quite often as locants in nomenclature and because this superscript position on an element symbol is used to indicate an ionic charge (Ref.

 Greek numerical prefixes Information
Numerical prefixes can be used to construct words that refer to a specific quantity of something.
In practice, people often use the Latin prefixes nona and "undeca" for 9 and 11 instead of the Greek ennea and "hendeca".
Prefixes above 12 are not commonly used, except 20 in icosahedron, 100 in hectare, and 1000 in the metric system.

 Prefix   (Site not responding. Last check: 2007-11-07)
In linguistics, a prefix is a type of affix that precedes the morphemes to which it can attach.
In English, most prefixes are bound morphemes, meaning that they cannot occur as independent words (excluding citational uses, e.g., saying "Speaking of the prefix, un-,...").
In the syntax of notations used in mathematics and computer science, prefix is used to describe an operator such as the usual addition sign + that is taken to bind to the variables succeeding them.

Considering the context, however, (preceding exa-) it is the Greek prefix for "five", penta-, minus the letter "n".
On the other hand, exa- has been reduced to three letters by dropping the "h" from hexa-, the Greek prefix for "six", possibly because the "h" would be silent in standard French.
(If tera- for 10**12 were taken to mean the Greek prefix for "four", te(t)ra-, minus the second letter "t", that would be an additional reason for its being followed by pe(n)ta- as the prefix for "five".

 R-0.1.4 Numerical (multiplicative) prefixes
These are derived from Greek and Latin number names and are the principal method for describing a multiplicity of identical features of a structure in chemical nomenclature (see R-4.1, especially Table 11).
R-0.1.4.2 The numerical prefixes "bis-", "tris-", "tetrakis-", etc., which, except for "bis-" and "tris-", are derived by adding "kis-" to the simple numerical prefixes (see Table 11), are used to indicate a multiplicity of substituted substituent prefixes or functional modification terms.
Such prefixes are also used when the use of "di-", "tri-", etc., is (or could be) ambiguous; this usually happens when an analogue of the term being multiplied being with a simple numerical prefix.

In either case, the alternative numeric naming approach is to give the numbers of atoms of each element in the molecule, using Greek prefixes.
The first ten Greek prefixes are: 1, mono; 2, di; 3, tri; 4, tetra; 5, penta; 6, hexa; 7, hepta; 8, octa; 9, nona; and 10, deca.
The prefix nona is Latin rather than Greek; the Greek prefix, used only in very specialized chemical nomenclature, would be ennea.

While no sugars are found in nature containing less than six atoms of carbon, synthetic compounds are formed belonging in the first, or monosaccharide, class which contain three, four, and five atoms of carbon, as well as others containing seven, eight, and nine atoms of carbon.
The nomenclature of the sugars is based upon the fact that simple sugar molecules are distinguished by the Greek prefixes tri, tetra, penta, etc., indicating the number of carbon atoms in the molecule; thus, glycerose, C
These simple sugar molecules are taken as the basis for a secondary classification based upon the number of monoses or simple sugar molecules represented in the molecular structure of the more complex members of the group.

Arabic numerals other than numerical values of quantities may be printed in lightface or bold italics, or in bold roman type, but lightface roman type is usually preferred.

The older prefixes, kilo-, mega-, giga-, and tera-, are generally understood to be derived from the ancient Greek words for "thousand," "large," "giant," and "monster," respectively.
According to a CGPM report, prefixes meaning "five" and "six" are used because 10**15 and 10**18 are fifth and sixth in the ascending series 10**3, 10**6, 10**9, and 10**12.
The use of Greek words for magnitudes through 10**12 turns out to be awkward in the late twentieth century, since it is difficult to extend the series easily.

The Greek numerical prefixes are not limited to the naming of polygons; they are the basis of the systematic naming of other families of scientific objects which depend on some primary count.
One important example is the (extended) official nomenclature for organic molecules, based on the number of carbon atoms in the backbone of the molecule, as established in 1957 by the IUPAC (International Union of Pure and Applied Chemistry).
