Numeral prefix

Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. In English and many other languages, they are used to coin numerous series of words. For example:

• simplex, duplex (communication in only 1 direction at a time, in 2 directions simultaneously)
• unicycle, bicycle, tricycle (vehicle with 1 wheel, 2 wheels, 3 wheels)
• dyad, triad, tetrad (2 parts, 3 parts, 4 parts)
• quadruped, hexapod
  (animal with 2 feet, 4 feet, 6 feet)
• September, October, November, December (7th month, 8th month, 9th month, 10th month)^[A]
• octal, decimal, hexadecimal
  (numbers expressed in base 2, base 3, base 8, base 10, base 16)
• septuagenarian, octogenarian (a person 70–79 years old, 80–89 years old)
• centipede, millipede (subgroups of arthropods with around 100 feet, or around 1000 feet)

In many European languages there are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position.^[B] There is also an international set of metric prefixes, which are used in the world's standard measurement system; many or most of the prefixes are distorted forms the words and roots shown below.^[C]

Table of number prefixes in English

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is extended to bis- before a vowel; among the other monosyllables, du-, di-, dvi-, and tri-, never vary.

Words in the cardinal catgegory are

such as the English first, second, third, which specify position of items in a sequence. In Latin and Greek, the ordinal forms are also used for fractions for amounts higher than 2; only the fraction  1 / 2 has special forms.

The same suffix may be used with more than one category of number, take for example the following:

Ordinal numbers	primary	secondary	tertiary	quartary [citation needed]	quintary	sextary	septimary	octavary	nonary	decimary
Distributive numbers	singulary [citation needed]	binary	ternary, trinary	quaternary	quinary	senary	septenary	octonary	novenary	denary

For the hundreds, there are competing forms: Those in -gent-, from the original Latin, and those in -cent-, derived from centi-, etc. plus the prefixes for 1 through 9 .

Many of the items in the following tables are not in general use, but may rather be regarded as coinages by individuals. In scientific contexts, either

are used to express very large or very small numbers, and not unwieldy prefixes.

Examples

Occurrences

• Numerical prefixes occur in 19th-, 20th-, and 21st-century coinages, mainly the terms that are used in relation to or that are the names of technological innovations, such as hexadecimal and bicycle. Also used in medals that commemorate an anniversary, such as sesquicentennial (150 years), centennial (100 years), or bicentennial (200 years).
• They occur in constructed words such as systematic names. Systematic names use numerical prefixes derived from Greek, with one principal exception, nona-.
• They occur as prefixes to units of measure in the
  SI prefix
  .
• They occur as prefixes to units of computer data. See
  binary prefixes
  .
• They occur in words in the same languages as the original number word, and their respective derivatives. (Strictly speaking, some of the common citations of these occurrences are not in fact occurrences of the prefixes. For example: millennium is not formed from milli-, but is in fact derived from the same shared Latin root – mille.)

Because of the common inheritance of Greek and Latin roots across the

borrowing

of 19th and 20th century coinages into many languages, the same numerical prefixes occur in many languages.

Numerical prefixes are not restricted to denoting integers. Some of the SI prefixes denote negative powers of 10, i.e. division by a multiple of 10 rather than multiplication by it. Several common-use numerical prefixes denote

vulgar fractions

.

Words containing non-technical numerical prefixes are usually not hyphenated. This is not an absolute rule, however, and there are exceptions (for example:

SI prefixes

and binary prefixes are not hyphenated, by definition.

Nonetheless, for clarity, dictionaries list numerical prefixes in hyphenated form, to distinguish the prefixes from words with the same spellings (such as duo- and duo).

Several technical numerical prefixes are not derived from words for numbers. (mega- is not derived from a number word, for example.) Similarly, some are only derived from words for numbers inasmuch as they are word play. (Peta- is word play on penta-, for example. See its etymology for details.)

The root language of a numerical prefix need not be related to the root language of the word that it prefixes. Some words comprising numerical prefixes are hybrid words.

In certain classes of systematic names, there are a few other exceptions to the rule of using Greek-derived numerical prefixes. The IUPAC nomenclature of organic chemistry, for example, uses the numerical prefixes derived from Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1 to 4 (meth-, eth-, prop-, and but-), which are not derived from words for numbers. These prefixes were invented by the IUPAC, deriving them from the pre-existing names for several compounds that it was intended to preserve in the new system: methane (via methyl, which is in turn from the Greek word for wine), ethane (from ethyl coined by Justus von Liebig in 1834), propane (from propionic, which is in turn from pro- and the Greek word for fat), and butane (from butyl, which is in turn from butyric, which is in turn from the Latin word for butter).

4. ^ The numbering adjectives in Greek are inflectional for grammatical gender (i.e. there is monos [masculine for single/alone], mone [feminine for single/alone] and monon [neuter for single/alone]), grammatical case (i.e. nominative, genitive, etc.) and grammatical number (singular/plural). The prefixes are produced from the default grammatical type (masculine/nominative/singular).
5. ^ Demi- is French, from Latin di·mi·di·um.

   In particular, quad·ri- has the alternate form quad·ru- before p in some Latin words, such as quad·ru·ple.
10. ^ Sometimes Greek hex·a- is used in Latin compounds, such as hexadecimal, due to taboo avoidance with the English word sex.
11. ^ For Latinate 21, 22, etc., the pattern for the teens is followed: un·vigint-, duovigint-, etc. For higher numbers, the reverse order may be found: 36 is tri·ginti·sex-. For Greek, the word kai ("and") is used: i·cosi·kai·hena-, icosi·kai·di-, penta·conta·kai·penta-, etc. In these and in the tens, the kai is frequently omitted, though not in triskaidekaphobia. (The inconsistency of tris·kai·deka·phobia with the table above is explained by the fact that the Greek letter kappa can be transliterated either "c" or "k".) In chemical nomenclature, 11 is generally mixed Latin-Greek undeca-, and the 20s are based on -cos-, for example tri·cos- for 23.
12. ^ In organic chemistry, most prefixes are Greek but the prefixes for 9 and 11 are Latin.
