lisääntynyt

Lisääntynyt is the past participle of the Finnish verb lisääntyä, meaning to increase or to multiply. It is used as an adjective or as part of verb phrases to indicate that something has increased in amount, number, or extent. The form can modify a noun, as in lisääntynyt määrä (an increased amount), lisääntynyt tarve (an increased need), or appear predicatively in a clause, for example Väestö on lisääntynyt (the population has increased).

Grammar and usage notes: lisääntyä is a intransitive verb describing growth or multiplication. The participle lisääntynyt marks a completed increase and can function similarly to an ordinary adjective. It agrees with the noun it modifies in number and case. In sentences with a copula, the construction expresses a state resulting from prior change: Väestö on lisääntynyt. In plural contexts, other participle forms such as lisääntyneet may appear (e.g., hinnat ovat lisääntyneet).

Etymology and related forms: lisääntynyt comes from lisääntyä, where lisää means “more” or “additional” and -nty- forms a participial stem. Related forms include lisääntyminen (the noun meaning “increase/multiplication”) and lisääntymistapa (a grammatical term referring to the participial form).
