Reilusti

Reilusti is a Finnish adverb that describes the manner or degree of an action, often translated as “fairly,” “generously,” or “considerably,” depending on the context. It derives from the adjective reilu (fair, generous) with the adverbial suffix -sti, and it is used in both spoken and written Finnish to intensify how something is done or to express a large margin or amount.

As a manner adverb, reilusti can indicate that something is performed in a fair or decent way, or with ample effort. As a degree adverb, it emphasizes size or extent, similar to phrases like “considerably” or “well over.” Its tone is generally neutral to slightly informal, and it is common in everyday language as well as in media and formal writing when emphasis is intended.

Typical usages include modifying verbs or adjectives. For example: “Hän lahjoitti reilusti rahaa hyväntekeväisyyteen” (He donated a generous amount of money to charity); “Hinta on reilusti halvemmalla kuin kilpailijoilla” (The price is considerably cheaper than the competitors’); “Suoritus parani reilusti viime vuodesta” (Performance improved considerably from last year).

Etymologically, reilusti shares its root with reilu, emphasizing fairness or abundance, and the suffix -sti marks it as an adverb. It is a standard part of Finnish vocabulary and remains widely understood across dialects.
