arvailuihin

Arvailuihin is a Finnish linguistic term describing the illative plural form of the noun arvailu, which means estimation, guesswork, or conjecture. The form arvailuihin is used when referring to multiple estimates or to the act of moving toward or focusing on estimates within a clause. It follows Finnish inflection patterns for illative plural, attaching a plural illative ending to arvailu. In practice, arvailuihin appears mainly in linguistic analyses, statistical discussions, and written texts that describe uncertainty in numbers; it is uncommon in ordinary speech.

Semantics and usage: Arvailuihin signals that the figures or conclusions are approximate rather than exact. It is typically found in contexts discussing uncertainty, forecasting, or estimation processes, where estimates form the basis of argument rather than precise values. The term can help distinguish between rough estimates and firmer assessments in analytical writing.

Related terms include arvailu (the act of guessing), arvio (an estimate or assessment), and epävarmuus (uncertainty). As a standard Finnish form, arvailuihin can appear in dictionaries, grammar descriptions, and academic writing that illustrate illative plural usage and the expression of speculative figures.
