Korostua

Korostua is a Finnish verb that means to become emphasized, to stand out, or to become noticeable. It is used to describe something gaining prominence in perception, discourse, or presentation, such as a feature in speech, a detail in text, or an element in design that draws attention.

In linguistic and stylistic contexts, korostua refers to the emergence of emphasis or focus. For example, intonation in speech can cause a syllable or word to korostua, and in writing a particular term may korostua through typographic choices or layout. In design and media, contrast, size, or color can cause certain elements to korostua within a composition.

Grammatically, korostua is an intransitive verb, meaning it does not take a direct object. It is typically used with present and past tense forms such as korostuu (present) and korostui (past), along with the regular Finnish conjugation for other persons and moods.

Etymology traces korostua to the root korost- from korostaa, which means “to emphasize” or “to stress,” with the reflexive or intransitive suffix -ua that forms verbs describing a change of state.
