arviomaasta

Arviomaasta is a Finnish participial adverb that derives from the verb arvioida, meaning "to estimate." The form –maasta combines the present participle –mää + the prepositional case –asta, indicating an action performed "by estimating." It is used to describe a subsequent action that follows an estimation, similar to the English construction "after estimating." For example, arviomaasta voidaan tarkentaa, meaning "it can be refined after estimating." This adverbial participle is common in technical and scientific writing to denote actions that are conditioned on an earlier assessment, and it functions similarly to other Finnish –maasta derivatives such as tutkimusmaasta ("after researching") and laskemassa ("while calculating").
