puumaisilla

Puumaisilla is a Finnish adjective form that denotes something made of wood or having a wood-like quality, and it is specifically the adessive plural form of the adjective puumainen. In Finnish, adjectives decline to match the noun they describe, including number and case, so puumainen becomes puumaiset in the nominative plural and puumaisilla in the adessive plural (used to indicate location or the manner of being described).

Etymology and grammar: The base puumainen combines the stem puu meaning wood with the suffix -mainen to form an adjective meaning wooden or wood-like. When the phrase describes multiple nouns in the adessive case, the form shifts to puumaisilla, as in puumaisilla lattioilla (on wooden floors) or puumaisilla pinnoilla (on wooden surfaces). This construction is common in descriptive prose, architecture texts, and interior design language.

Usage: Puumaisilla is most often found in written descriptions of spaces, objects, or materials where a wood-based appearance or composition is emphasized. It contrasts with other forms such as puumainen (wooden-like in a general sense) or puuta muistuttava (resembling wood). The choice of puumaisilla signals a plural referent and situates the description in a spatial or locational context.

Examples:

- Puumaisilla lattioilla on lämmin tunnelma.

- Puhdas, puumaisilla pinnoilla näkyy puun kuviointi.
