liikuttuvan

Liikuttuvan is a Finnish grammatical form. It is the genitive singular of the adjective liikuttuva, which means “moving” or “capable of movement.” In Finnish, adjectives decline to agree with the noun they modify, and when the noun is in the genitive case, the adjective takes the corresponding genitive form, yielding liikuttuvan.

Usage in language and terminology: Liikuttuvan is commonly found in descriptive or scientific prose to attribute movement to the referenced noun. Typical phrases include liikuttuvan kappaleen nopeus (the speed of the moving particle) or liikuttuvan ihmisen havainnot (the observations of the moving person). The form signals that the noun is being described as actively in motion or subject to movement.

Relation to related forms: Liikuttuvan is closely connected to other movement-related Finnish adjectives such as liikkuva (“moving”) and liikuttava (“causing movement”). The choice between them depends on nuance: liikuttuva emphasizes the capacity or state of being in motion, while liikkuva often stresses actual movement, and liikuttava can describe something that induces movement.
