== Numerals ==
Numerals 1–10 in colloquial spoken Finnish:
#{{lang|fi|yks}} ({{lang|fi|yksi}})
#{{lang|fi|kaks}} ({{lang|fi|kaksi}})
#{{lang|fi|kolme}} ({{lang|fi|kolme}})
#{{lang|fi|neljä}} ({{lang|fi|neljä}})
#{{lang|fi|viis}} ({{lang|fi|viisi}})
#{{lang|fi|kuus}} ({{lang|fi|kuusi}})
#{{lang|fi|seittemä(n)}} ({{lang|fi|seitsemän}})
#{{lang|fi|kaheksa(n)}} ({{lang|fi|kahdeksan}})
#{{lang|fi|yheksä(n)}} ({{lang|fi|yhdeksän}})
#{{lang|fi|kymmene(n)}} ({{lang|fi|kymmenen}})
Numbers 11-19 are formed by appending {{lang|fi|-toista}}, which can be shortened to {{lang|fi|-toist}}. Numbers 20-90 are formed by appending {{lang|fi|-kymmentä}}, which can be shortened to {{lang|fi|-kymment}} or even {{lang|fi|-kyt(ä)}}. {{lang|fi|Kolme}}, {{lang|fi|neljä}} and {{lang|fi|seittemän}} can be abbreviated to {{lang|fi|kol-}}, {{lang|fi|nel-}} and {{lang|fi|seit-}} with {{lang|fi|-kytä}}, but not independently, as in {{lang|fi|kolkytäkolme}} "33" or {{lang|fi|seitkytäneljä}} "74".

When counting out loud, even shorter forms are used, mostly one-syllable words with long vowels:
#{{lang|fi|yy}}
#{{lang|fi|kaa}}
#{{lang|fi|koo}}
#{{lang|fi|nee}}
#{{lang|fi|vii}}
#{{lang|fi|kuu}}
#{{lang|fi|sei}} / {{lang|fi|see}}
#{{lang|fi|kas(i)}}
#{{lang|fi|ys(i)}}
#{{lang|fi|kymp(pi)}}
{{lang|fi|-toista}} becomes {{lang|fi|-toi}}, {{lang|fi|-too}} or even {{lang|fi|-to}}. {{lang|fi|-kymmentä}} becomes {{lang|fi|-kyt}}, with 20-60 typically retaining their longer numeral forms (e.g. {{lang|fi|kakskyt}} rather than {{lang|fi|**kaakyt}} for 20). 70 is typically {{lang|fi|seitkyt}} or {{lang|fi|seiskyt}}, while 80 and 90 do with {{lang|fi|kasi-}} and {{lang|fi|ysi-}}.

The [[Numeral system|numerals]] 1&ndash;9 have their own names, different from the [[cardinal number (linguistics)|cardinal numbers]] used in counting. Numbers that have longer names are often shortened in speech. This may be problematic for a foreigner to understand, if they have learnt words by book:

:{{lang|fi|ykkönen}} (number one)
:{{lang|fi|kakkonen}} (number two)
:{{lang|fi|kolmonen}} (number three)
:{{lang|fi|nelonen}} (number four)
:{{lang|fi|viitonen}} (number five) → {{lang|fi|vitonen}}, {{lang|fi|femma}} ([[Helsinki slang]])
:{{lang|fi|kuutonen}} (number six) → {{lang|fi|kutonen}}
:{{lang|fi|seitsemäinen}} (number seven) → {{lang|fi|seiska}}
:{{lang|fi|kahdeksainen}} / {{lang|fi|kahdeksikko}} (number eight) → {{lang|fi|kasi}} / {{lang|fi|kaheksikko}}
:{{lang|fi|yhdeksäinen}} / {{lang|fi|yhdeksikkö}} (number nine) → {{lang|fi|ysi}} / {{lang|fi|yheksikkö}}
:{{lang|fi|kymmenen}} → {{lang|fi|kymppi}}, {{lang|fi|kybä}} ([[Helsinki slang]])

The {{lang|fi|-kko}} suffix normally denotes a group of x people, but on 8 and 9, it doubles as a synonym for the numeral's name. {{lang|fi|Kahdeksikko}} is also used to describe a figure eight shape.

The regular {{lang|fi|-Onen}} / {{lang|fi|-inen}} forms can additionally be used of objects with an ID number. For example, bus 107 is called {{lang|fi|sataseiska}}, and a competition winner is an {{lang|fi|ykkönen}} (not {{lang|fi|*sataseittemän}} or {{lang|fi|*yks}}.)
