Latin numerals

from Wikipedia, the free encyclopedia

Latin numerals : There are four basic types of numerals in Latin :

  1. Basic numbers ( cardinal numbers ) (one, two, three ...)
  2. Ordinal numbers (the first, the second, the third ...)
  3. Distribution numbers ( distributive numbers ) (single, two each, three each ...)
  4. Repetition numbers ( iterative numbers ) (once, twice, three times ...)

The Latin numerals that end in eight or nine (18, 19, 28, 29, ... to 88, 89) are predominantly formed subtractively : duo-de-viginti '18', literally 'two from twenty down'; un-de-viginti '19', literally 'one of twenty down'.

declination

The ordinal numbers are declined , as are the distributive numbers under a thousand, of the cardinal numbers those from 'one' to 'three' ( unus , duo , tres ) as well as the multiples of one hundred ( ducenti etc.) as well as the plural milia 'thousand (e) '.

(°) The order of the genera is masculine, feminine, neuter. The plural of unus occurs with pluraliatum .
(*) The same applies to the diffraction of the remaining hundreds.
(#) mīlia is a number noun; the object to be counted is in the genetivus partitivus, e.g. B. tria mīlia mīlitum 'three thousand soldiers'.

unio, unionis, unioni, unionem, unione is feminine, binio etc. inflect the same way, but are masculine. The higher number nouns are not used.

Cardinal numbers

unus

The numeral ūnus < Old Latin oinos ' ein ', leads with Old Irish óen ' ein ', Gothic ains ' ein ', ancient Greek οἴνη oínē 'one on the cube' and the fore link from Old Church Slavonic inorogŭ 'unicorn' in Urindo European * Hoi̯-no-s back. The genitive ūnīus , ūnĭus and the dative ūnī follow the pronominal declension ( hujus , illius etc.), the other forms (and the rare gen. F. Ūnae ) follow the adjectival a- / o-declension .

In the Romance languages, nominative and accusative forms live on as numerals and indefinite articles , such as Old French , Occitan us / une / un , Italian un / una , Spanish uno / una , Portuguese um / uma , Romanian un / o etc.

duo

The masculine nominative / accusative Duo <altlateinisch Duo , two 'leads with old Welsh dou , two' ancient Greek δύω DYO , two ', an ancient Indian Duva , two' Altkirchenslawisch Duva , two 'on urindogermanisch * duu̯o-h 1 back, the Lindeman variant to monosyllabic * duo-h 1 , which in Sanskrit द्वा DVA , two 'and transformation in gothic TWAI , Neuhochdeutsch two is continued etc.; * duu̯ah 2 -ih 1 is used as a preliminary form of the feminine dŭae . Both forms are formed with a dual ending , which otherwise only left a trace in Latin with ambō 'both'. The accusative forms dŭōs m., Dŭās f., The genitive dŭom , new dŭōrum m./n., Dŭārum f. as well as the dative / ablative dŭōbus m./n., dŭābus f. are neoplasms; sometimes duo also occurs in these cases, especially in connection with non-inflected tens such as duo et viginti , duodetriginta .

tres

The masculine and feminine nominative trēs leads back with Gothic þreis 'three', ancient Greek τρεῖς treîs 'three', ancient Indian त्रयः trayaḥ 'three' to Urindo-European * trei̯-es ; since Old Latin it has also penetrated the accusative and displaces its original form trīs , which continues with Umbrian trif , Gothic þrins , Old Irish trí , Greek τρίνς tríns urindo -European * tri-ns . The neuter tria corresponds to Umbrian triia , Greek τρία tría . The genitive trium goes back directly to Indo-European * trii̯-om (in contrast to Greek τριῶν triôn with long -ōn- < -o-om of the o-declension ), the dative / ablative tribus with Umbrian tris <* trifos in Indo-European * tri -bʰos .

Other numerals

There are also words for single, double , etc. (multiplicatives and ratio words ), such as:

  1. simplex (genitive: simplicis) - simplus (-a, -um)
  2. duplex - duplus
  3. triplex - triplus
  4. quadruplex - quadruplus

There is also a hierarchical form of the ordinalia, which is given in German in the first place :

  1. prīmarius
  2. secundarius
  3. tertiary

However, these words are not used for (most) higher numbers.

multiplication

The iterative and distributive numbers are used when multiplying:

is called quīnquiē (n) s quaterna sunt vīgintī , so: 'five times four are twenty'.

Fractions

Latin has no fractions ( partitiva ; like German third, quarter ), the rule is:

  • If the numerator is exactly one less than the denominator, then partes is written .
  • Counter one is pars .
  • Otherwise the genitive of the ordinal number stands for the denominator:
dimidia pars 'half part', tertia pars 'third part', duae partes ('two parts'), tres partes ('three parts'), tres quintae ('three fifths').
dimidia is a special formation for dīmidius, -a, -um 'half, not quite' from dis and medius 'medium'.

Compositions

There are also many words that contain numbers. Here is a selection:

  1. ūnifōrmis - uniform
  2. duplicārius - double mercenary
  3. trivium - three-way, fork in the road (generally known place, compare " trivial ")
  4. quadrātus - square, compare " square "
  5. quīnquennium - five years
  6. sextārius - a "bottle" of 1/6 congius, about 1/2 liter (54 cl)
  7. [mensis] september - the 7th month (before 153 BC ), corresponding to october, november, december
  8. octipēs - eight feet
  9. nōnāria - ancient street girls (they were only allowed to work from the 9th hour, hence the name)
  10. decennis - ten years old

The zero

The Romans knew linguistic expressions for “not something” ( nullum ) and “nothing” ( nihil ), but no number sign and no separate mathematical term for a number value “ zero ”.
