Epämuuttuvuudella

Epämuuttuvuudella is a Finnish grammatical form that literally means “with immutability.” It is the adessive case form of the noun epämuuttuvuus, which denotes immutability or unchangeability. In linguistic terms, the ending -lla marks a means, attribute, or state by which something is described or performed, so epämuuttuvuudella can be understood as referencing immutability as a characteristic or instrumental condition.

Etymology and grammar: The base word epämuuttuvuus is formed from epä- (non-, un-) and muuttuva (mutable), with the noun suffix -vuus. The noun can take various case endings, of which -lla is the adessive (“on/at/with”). Thus epämuuttuvuudella literally means “with immutability” and is used to express the manner or principle by which something is done or evaluated.

Conceptual use: In philosophy, theology, mathematics, and physics, immutability refers to the property of not changing over time or under specified transformations. Immutable objects, fixed laws, or constant quantities are discussed as examples of such invariance. The term relatedly contrasts with muuttuvuus (changeability) and with the broader idea of invariants that remain unchanged under certain operations.

Usage in Finnish texts: The form epämuuttuvuudella appears primarily in formal, analytical, or theoretical writing. It signals that immutability serves as the basis, means, or condition under discussion. It is less common in everyday language, where more direct phrases are typically used.
