Vaihtua

Vaihtua is a Finnish intransitive verb meaning to change, to become different, or to vary over time. It describes a transition from one state, condition, or form to another, and can apply to physical changes as well as abstract developments, such as situations, conditions, or policies. The verb is often used to convey that something is not fixed but subject to alteration.

Usage notes and examples: Vaihtua is used for changes that occur naturally or over a period of time, as well as for changes in circumstances or appearances. Examples include: Sää vaihtuu päivän mittaan. (The weather changes throughout the day.) Hinta vaihtuu usein. (The price changes often.) Ajan kuluessa asiat vaihtuvat. (Over time, things change.) In some contexts it can imply a shift to a different state or identity, for example: Tilanteet voivat vaihtua nopeasti. (Situations can change quickly.)

Grammar and forms: Vaihtua is an intransitive verb and is conjugated like other Finnish -ua verbs. Common finite forms include vaihtuu (present, third person singular), vaihtui (past), and on vaihtunut (present perfect). The verb is often used with nouns referring to states or conditions, such as tilanne, sää, hinta, or elämä, to describe a transition from one condition to another.

Etymology and related terms: Vaihtua is linked to the root vaih- found in related words such as vaihto and vaihtaminen, which express change, exchange, or substitution. The related transitive verb vaihtaa means to swap or replace something, whereas vaihtua focuses on the subject undergoing a change rather than performing an action on an object.
