25kertainen

25kertainen is a Finnish term indicating twenty-five times as much, or twenty-fivefold. It functions as a multiplier expression used in mathematics, statistics, business, and everyday language to describe a quantity relative to a base amount. In standard Finnish the conventional written form is 25-kertainen, while 25kertainen can appear in headlines, branding, or other contexts where hyphenation is omitted.

The concept belongs to a broader family of numerically formed multiplicatives, such as kaksikertainen (twofold), kolmikertainen (threefold), and viisikertainen (fivefold). These terms are used to convey scale or comparison, for example "tulos on 25-kertainen alkuperäisestä" meaning "the result is twenty-five times the original." The exact usage can vary with style guides, particularly regarding hyphenation and how the term inflects when combined with nouns in different cases.

Formation and usage notes: The core element is the numeral combined with kertainen to express the degree of multiplication. While 25-kertainen is the clearest standard form, contexts such as headlines, branding, or data labels may use 25kertainen without a hyphen. The term is primarily adjectival and is most common in formal or technical writing, but it also appears in media and marketing to describe scale, growth, or comparison.

Related terms in Finnish convey similar ideas of multiplicative size, and 25kertainen shares the same grammatical and semantic role as other -kertainen forms within the language.
