Puhdistettuja

Puhdistettuja is a Finnish adjective form meaning cleaned or purified, derived from the verb puhdistaa. It is the plural partitive form of the past passive participle puhdistettu. As an adjective, puhdistettuja describes nouns that have undergone cleaning or purification, and it is used when the noun it modifies is in the partitive case or when the quantity is indefinite.

In practice, puhdistettuja is used with plural nouns in the partitive case, for example: puhdistettuja astioita (cleaned dishes), puhdistettuja vaatteita (cleaned clothes), puhdistettuja tietoja (cleaned data). The contrast to the nominative plural form, puhdistetut, occurs when the noun is in the nominative: puhdistetut astiat (the cleaned dishes). The partitive form often appears in statements that imply an indefinite quantity or a non-specified amount, such as Tarvitsemme puhdistettuja astioita (We need cleaned dishes) or Tutkimuksessa käytetään puhdistettuja tietoja (The study uses cleaned data).

Contexts: the term is common across everyday language and technical domains, including housekeeping, food service, manufacturing, and data processing, where items have been sanitized, cleaned, or purified.

Etymology and morphology: the root puhdista- combines with the past passive participle suffix -ettu to form puhdistettu, and the plural partitive suffix -ja/-ja yields puhdistettuja to agree with a plural partitive noun. The form is a standard example of how Finnish participles function as adjectives and how case and number agreement affect inflection.
