Tukkeutuneisiin

Tukkeutuneisiin is a Finnish grammatical form: it is the illative plural of the adjective tukkeutunut, meaning “blocked” or “clogged.” It is used with plural nouns in the illative case, which marks direction or movement into something. The form comes from the past participle tukkeutunut (blocked) and is declined to agree with a plural noun in illative, for example tukkeutuneisiin putkiin (into clogged pipes) or tukkeutuneisiin viemäriin (into clogged sewers).
