Tilavuudessaan

Tilavuudessaan is a Finnish inflected form of the noun tilavuus, meaning volume or capacity. The form combines the inessive case marker and a third-person possessive suffix, yielding a expression that translates roughly to "in its volume" or "within its capacity." The exact construction reflects Finnish grammar, where the location marker -ssa/-ssä (in) is joined with the possessive suffix -nsa/-nsä (his/her/its).

In use, tilavuudessaan appears in descriptive or technical contexts where an object's interior space or capacity is being referenced. It often serves to frame statements about what can fit inside something, how large something is relative to its own interior, or how measurements pertain to the object’s internal volume. Because it is a distal, domain-specific construction, it tends to occur in technical writing, engineering descriptions, or scientific prose rather than everyday casual speech.

Etymology-wise, tilavuudessaan derives from tilavuus (volume) with the typical Finnish compound suffixes for possession and location. It exemplifies how Finnish nouns can be extended to convey precise spatial and possessive relations within a single word. Related terms include tilavuus (volume) and other inflected forms that mark location (ssa/ssä) and possession (-nsa/-nsä).
