kävellessään

Kävellessään is a Finnish construction preposition used to express the action of walking along or alongside something. It can be translated to English as "while walking along" or "while passing by".

In Finnish grammar, kävellessään is a partitive form of the verb kävellä, which means "to walk". The suffix -ssään is a neuter object form indicating the action of walking refers to a situation where an object is moving or changing, often described in a more general sense. Kävellessään is usually combined with a noun phrase that describes the location or the thing being walked along.

Kävellessään is often used in conditional and subordinate clauses to describe a situation where something happens in relation to the walking action. It can also be used in a more abstract sense to describe a state or a feeling experienced while walking.
