kolmekymmentä

Kolmekymmentä is the Finnish word for the number thirty. It is a cardinal numeral and is written as a single word. In Finnish, numbers from 21 to 99 are formed by combining the tens with the units, and kolmekymmentä represents the tens for thirty.

Etymology and form: Kolmekymmentä is formed from kolme, meaning three, and kymmentä, the partitive plural form of kymmenen, meaning ten. This construction is used for all tens in Finnish, producing forms such as kaksikymmentä (twenty), kolmekymmentä (thirty), and neljäkymmentä (forty).

Usage: Kolmekymmentä is used with nouns to indicate the quantity thirty or to state age. Examples include kolmekymmentä ihmistä (thirty people) and kolmekymmentä vuotta vanha (thirty years old). In written form the number can also be written as 30, but kolmekymmentä is the standard word form in text. The accompanying noun is declined according to case and number, for instance kolmekymmentä euroa (thirty euros) or kolmekymmentä vuotta vanha.

Notes: Finnish numerals from 20 onward create compound forms that are treated as single words in standard writing. Kolmekymmentä, like other tens forms, functions as a base for larger numbers and is a common component in everyday counting, dates, ages, prices, and measurements.
