Jäätyessä

Jäätyessä is a Finnish form derived from the verb jäätyä, meaning to freeze or to become solid. Grammatically, it is an adverbial participle that expresses a time or condition during which a freezing process occurs. In English it is commonly rendered as “as/when something freezes” or “in the act of freezing.”

Grammatically, jäätyessä is the inessive participle form of jäätyä and is used to introduce adverbial clauses of time or condition. It signals that the action described in the main clause happens simultaneously with or as a result of the freezing process. It can appear at the start of a clause or after conjunctions such as kun.

Contexts for its use include descriptions of natural processes (ice formation on bodies of water, roads, and exposed surfaces during cold weather), food preservation and processing (freezing of products), and engineering or material science discussions where a material is described as it freezes.

Examples:

Vesi jäätyy, ja jäätyessä veden tilavuus voi muuttua.

Kun pakkaset ovat kovat ja vesi jäätyy, routa muodostuu.
