perusteella

Perusteella is a Finnish adverb meaning “on the basis of” or “based on.” It is used to indicate the grounds, reasons, or sources for a claim, decision, or conclusion. The word functions as an adverbial modifier, connecting a statement to its grounds rather than acting as a stand-alone preposition.

Etymology and form: Perusteella is formed from the noun peruste, meaning basis, foundation, or reason, with the suffix -lla to indicate location or basis. The form is used in phrases such as perusteella or in compounds like perusteella tehty, meaning “done on the basis of.” Typical collocations include perusteella kerätyt tiedot (data collected on the basis of) or perusteella tehty tutkimus (a study conducted on the basis of).

Usage: The term is common in formal, especially legal, administrative, and academic Finnish, but it also appears in everyday language when someone wants to specify the grounds for a statement. It often appears with nouns in the sentence that denote the basis, such as tiedot, todisteet, tai vaatimukset, to indicate that those grounds justify the subsequent claim or action. The form perusteella tehty is a common way to describe actions that were carried out based on certain grounds.

Related terms: The base noun is peruste (basis). Related adjectives and adverbs include perusteellinen (thorough, fundamental) and perusteellisesti (thoroughly). Other phrases used to convey similar meaning include sen mukaan and perusteen mukaan, depending on register and nuance. Perusteeton means baseless.

In summary, perusteella is a versatile Finnish term for attributing a claim or action to its underlying grounds, with frequent use in formal discourse and clear, precise emphasis on justification.
