kulmaisia

Kulmaisia is a Finnish linguistic term that refers to the plural partitive form of the adjective kulmainen, which means angular or corner-shaped. It is encountered mainly in descriptions of Finnish grammar and morphology, rather than as a separate lexical entry with its own meaning in everyday language.

Etymology and form: kulmainen is formed from the noun kulma, meaning corner, with the adjectival suffix -inen. In the plural partitive, adjectives take the ending -ia, producing kulmaisia. This form is used when describing multiple nouns that are in partitive or indefinite contexts, such as shapes or forms that are not fully counted.

Usage: Kulmaisia describes multiple objects that have an angular character. It is commonly seen in descriptive writing about architecture, design, or natural formations. An example is the phrase näytteillä on kulmaisia muotoja, meaning “the exhibit features angular shapes.” In Finnish, the adjective must agree with the noun in number and case, so kulmaisia appears when the modified noun is in a plural partitive context.

Relation to other terms: Kulmaisia is related to kulmainen (the base adjective meaning angular) and to other inflected forms such as kulmaiset (nominative plural) or kulmainen in other cases. It illustrates Finnish adjective inflection patterns, especially how the partitive plural ending -ia is used with descriptive adjectives.
