vertailuun

Vertailuun is a Finnish grammatical form that functions as the illative case of the noun vertailu, meaning “comparison.” In Finnish, illative forms typically express motion toward something or a purpose, so vertailuun can be understood as “into/for comparison.” It is used when the act or concept of comparing is the focus of the statement.

Morphology and etymology: The base word vertailu is a noun meaning “comparison,” derived from the verb vertaa, “to compare,” with the noun-forming suffix -lu. The illative suffix -uun (harmonized to -uun after a vowel stem) yields vertailuun. Thus the form explicitly marks direction toward comparison or the intended purpose of comparing elements such as data, products, or options.

Usage: Vertailuun is common in Finnish to introduce or specify the context of comparison in written and formal language. It appears in academic writing, market analysis, and consumer information where items are assessed against each other. It is often found in phrases describing what will be compared or what should be used for comparison, such as “vertailuun tarkoitettu mittaristo” (instrument set intended for comparison) or “vertailuun otettavat muuttujat” (variables to be used for comparison). Translations into English typically render vertailuun as “for comparison” or, in some contexts, “into the comparison.”
