roiskumaan

Roiskumaan is a Finnish verb meaning to splash, spray, or spatter a liquid, typically water, mud, paint, or coffee, by a forceful or sudden motion. The action can involve droplets flying in several directions or a stream of liquid hitting a surface. The related noun roiske refers to the splash or spray itself, and the verb roiskua is the broader term for this kind of movement.

The form roiskumaan is the ma-infinitive, a non-finite variant of the verb roiskua. It appears in clauses with auxiliary verbs such as alkaa (to begin) or jatkua (to continue), for example: Vesi alkaa roiskumaan, kun hana on auki. This form is used to describe an ongoing or potential action without a specified subject in that clause.

Common usage spans everyday spills and more deliberate spraying, such as water splashing around when a hose is on, or paint roiskumaan onto surfaces during cleaning or painting. The verb is transitive when a direct object is involved (roiskua vettä) and intransitive when the liquid itself splashes (vesi roiskuu). The expression can convey both accidental spills and intentional spraying.

In Finnish, roiskumaan and its related forms are typically taught as part of how liquids behave under motion, and they appear in both descriptive and instructional contexts. Synonyms and closely related terms describe varying degrees of spray or spatter, but roiskumaan specifically denotes the act of splashing in a general sense.
