sileämmät

Sileämmät is a Finnish adjective form meaning the smoother ones or more smooth. It is the plural nominative form of the comparative adjective sileämpi, which compares two or more items and indicates that they have a higher degree of smoothness than others. The base word is sileä, meaning smooth, and the comparative is formed with the suffix -mpi, following vowel harmony, yielding sileämpi; when pluralized in the nominative, the ending becomes sileämmät.

The word is used to describe physical properties such as surfaces, textures, or finishes, for example sutaining, coatings, or edges. It can also appear in metaphorical contexts where smoothness is used figuratively to imply polish, ease, or tact, such as in descriptions of procedures, presentations, or negotiations, though the literal sense of smoothness is most common.

Examples of usage include sentences like: Nämä levyt ovat sileämmät kuin nuo. Pinnan pitäisi olla sileämmät kiillotusprosessin jälkeen. In such sentences, sileämmät agrees in number with the noun it modifies, and the comparison is typically established with kuin or to be understood from context.

Grammatical notes: Finnish adjectives do not differentiate gender; the form sileämmät reflects plural nominative or, in some contexts, plural accusative. The related forms include sileä (smooth), sileämpi (smoother), and sileimmät (the smoothest).
