reilun

Reilun is a Finnish term that functions as the genitive singular form of the adjective reilu, meaning fair, honest, or generous. In Finnish, adjectives decline to agree with the noun they modify, so reilun appears in front of a noun in the genitive case to convey the sense of “of a fair …” or “fair-….”

In usage, reilun appears in compound noun phrases that express fairness or balance. Common examples include reilun pelin säännöt, meaning the rules of fair play, and reilun kaupan tuotteet, meaning fair-trade products. The form is widely used in everyday Finnish to describe conditions, practices, or prices that are considered fair or equitable.

Grammatically, reilun is the genitive singular inflection of reilu and is not a standalone noun. It serves to modify the following noun within a noun phrase, typically before a singular genitive noun such as peli (game) or kauppa (trade). The construction is a standard feature of Finnish adjective agreement and appears across various contexts where fairness or proportionality is being described.

There are no well-established uses of reilun as a distinct proper noun or as a title in mainstream sources. In practice, it functions primarily as a grammatical form within descriptive phrases rather than as an independent lexical item.
