Parillisista

Parillisista is the elative plural inflection of the Finnish adjective parillinen, which means “even” or “even-numbered.” It is used with plural nouns to express a relation to “the even numbers,” for example indicating source or origin, such as “from the even numbers” or “of the even numbers,” depending on the grammatical context.

In Finnish, adjectives agree with the nouns they modify in number and case. The word parillisista therefore signals that the accompanying noun is a plural term in the elative case. Related forms of the same adjective include parilliset (nominative plural), parillisten (genitive plural), parillisia (partitive plural), parillisissa (inessive plural), and singular counterparts such as parillisesta (elative singular) and parilliseen (illative singular). Understanding parillisista helps in parsing sentences that discuss sets or groups defined by parity, such as even numbers or even-numbered items.

Usage of parillisista commonly appears in mathematical, statistical, or linguistic contexts. Examples include phrases like parillisista luvuista (from the even numbers) or parillisista numeroista (about the even numbers). The form is not a standalone lexical item but a grammatical inflection that modifies a plural noun referring to even-valued elements. It is part of the broader Finnish system of adjective inflection and parity terminology.
