Cardinal numbers
The ordinary counting numbers (cardinals) from 0 to 10 are given in the table below. Cardinal numbers may be inflected and some of the inflected forms are irregular in form. Note: in parentheses, alternative form for counting, and colloquial. The dialectic-colloquial forms may leave the ''d'' off and sometimes also the genetive ending ''n'': ''yhden'' ⇒ ''yhe(n)''; ''kahden'' ⇒ ''kahe(n)''; ''viiden'' ⇒ ''viie(n)''; ''kuuden'' ⇒ ''kuue(n)''; ''kahdeksan'' ⇒ ''kaheksa(n)''; ''yhdeksän'' ⇒ ''yheksä(n)''. (Corresponding the formal and ordinary counting inTeens and multiples of ten
To form teens, ''toista'' is added to the base number. ''Toista'' is the partitive form of ''toinen'', meaning "second group of ten". Hyphens are written here to separate morphemes. In Finnish text, hyphens are not written. * ''yksi-toista'', ''kaksi-toista'', … ''yhdeksän-toista'' :one-second., two-second., … nine-second. :"one of the second, two of the second, … nine of the second" :11, 12, … 19 In older Finnish, all numbers were constructed like this. This usage is now considered archaic and the suffix ''toista'' is treated as a particle instead of meaning "of the second". * ''kaksi-kymmentä'', ''yksi-kolmatta'', ''kaksi-kolmatta'', … ''yhdeksän-kolmatta'' : two-ten., one-third., two-third., … nine-third. : "two tens, one of the third, two of the third, … nine of the third" : 20, 21, 22, … 29 * ''yksi-neljättä'', ''yksi-viidettä'' : one-fourth., one-fifth. : "one of the fourth, one of the fifth" : 31, 41 Even older forms included ''kymmentä'' at the end, giving for example ''yksi-toista-kymmentä'' "one of the second decade" for 11 and ''viisi-kolmatta-kymmentä'' "five of the third decade" for 25. The numbers for tens (20, 30, up to 90) are constructed this way: * ''kaksi-kymmentä'', ''kolme-kymmentä'', ''neljä-kymmentä'', … ''yhdeksän-kymmentä'' : two-ten., three-ten., four-ten., … nine-ten. : "two tens, three tens, four tens, … nine tens" : 20, 30, 40, 90 In modern Finnish, the numbers 21–29, 31–39, and so on are constructed as in English: * ''kaksi-kymmentä yksi'', ''kaksi-kymmentä kaksi'', ''kaksi-kymmentä kolme'' : two-ten. one, two-ten. two, two-ten. three : "two tens one, two tens two, two tens three" : 21, 22, 23Hundreds
100 is ''sata'', 200 is ''kaksisataa'' and so on. 1000 is ''tuhat'', 2000 is ''kaksituhatta'' and so on. So, 3721 is ''kolme-tuhatta-seitsemän-sataa-kaksi-kymmentä-yksi'' (actually written as one long word with no dashes in between).Years
In older Finnish, years were expressed by counting centuries. Use of this convention is archaic. For instance, ''yhdeksäntoistasataa kaksikymmentäkaksi'' "1922", instead of the modern ''tuhatyhdeksänsataa kaksikymmentäkaksi''. Long numbers (like 32534756) are separated in three-digit sections with space beginning from the end of the number (for example 32 534 756). Writing it with letters follow the spacing, in the example (in numbers over one million, ''miljoona'' "million" is written separately) ''kolme-kymmentä-kaksi miljoonaa viisi-sataa-kolme-kymmentä-neljä-tuhatta seitsemän-sataa-viisi-kymmentä-kuusi''. (No dashes, they are only to make the number look clear.)Inflection
Numbers can be inflected by case; all parts of the number except ''toista'' are inflected. Nouns following a number in theSets
Numerals also have plural forms, which usually refer to things naturally occurring in pairs or other similarly well-defined sets, such as body parts and clothing items. Also names of celebrations are usually in the plural. The plural forms are inflected in cases in the same way as the corresponding nouns. For instance: Numbers from one to seven are apparently original in etymology. The words ''kahdeksan'' "eight" and ''yhdeksän'' "nine" have no confirmed etymology. The old theory is that they are compounds: ''*kaks-teksa'' "10–2", or "eight" and ''*yks-teksa'' "10–1", or "nine", where the reconstructed word ''*teksa'' is similar to the Indo-European words for "ten" (*dek´m), but this is phonologically not plausible. Alternatively, they could be *''kakt-e-ksä'' and ''ykt-e-ksä'' "itself, without two" and "without one", where ''-eksa'' is a form of ''ei'' "no" inflected with the Karelian reflexive conjugation ("itself, without two").Ordinal numbers
These are the 'ordering' form of the numbers: "first, second, third", and so on. Ordinal numbers are generally formed by adding an ''-s'' ending, but ''first'' and ''second'' are completely different, and for the others the stems are not straightforward: For teens, the first part of the word is changed; however, the words for "first" and "second" lose their irregularity in "eleven" and "twelve": For twenty through ninety-nine, all parts of the number get the '-s' ending. 'First' and 'second' take the irregular form only at the end of a word. The regular forms are possible for them but they are less common. 100th is ''sadas'', 1000th is ''tuhannes'', 3721st is ''kolmas-tuhannes-seitsemäs-sadas-kahdes-kymmenes-ensimmäinen''. Again, dashes only included here for clarity; the word is properly spelled without them. Like cardinals, ordinal numbers can also be inflected: The ''toista'' in the 'teens' is actually the partitive of ''toinen'', which is why ''toista'' gets no further inflection endings. (Literally ''yksitoista'' , , one-of-the-second'.) Long ordinal numbers in Finnish are typed in almost the same way as the long cardinal numbers. 32534756 would be (in numbers over one million, ''miljoona'' "million" is written separately) ''kolmas-kymmenes-kahdes miljoonas viides-sadas-kolmas-kymmenes-neljäs-tuhannes seitsemäs-sadas-viides-kymmenes-kuudes''. (Still, no dashes.)Names of numbers
This is a feature of Finnish which does not have an exact counterpart in English (with the curious exceptions of calling a five-dollar bill a ''fiver'' and 9 ''niner'' in radio communication), but there is a counterpart in colloquialNumbers in the spoken language
In spoken Finnish the final ''i'' in ''yksi, kaksi, viisi, kuusi'', as well as the final ''a'' in the numbers 11-19, is frequently dropped. Other short forms can be heard for the tens, where the element ''kymmentä'' can be heard as "kyt": shortened words like ''kolkyt'' (30), ''nelkyt'' (40), ''viiskyt'' (50), ''kuuskyt'' (60), ''seiskyt'' (70), ''kaheksakyt'' (80), ''yheksäkyt'' (90) are not uncommon. When counting a list of items a kind of spoken shorthand can be heard. Thus, ''yksi kaksi kolme neljä viisi...'' may become ''yks kaks kol nel viis...'' or even ''yy kaa koo nee vii...'', but the forms can vary from person to person.References
