Pigmentoituneisiin

Pigmentoituneisiin is a Finnish grammatical form that functions as the illative plural of the participle adjective pigmentoitunut, meaning pigmented. As a modifier, it describes organisms, cells, or items that are part of a group characterized by pigmentation and indicates movement toward or into that group (illative case). In sentences it commonly appears with a plural illative noun, for example pigmentoituneisiin soluihin, meaning “into the pigmented cells.”

In usage, pigmentoituneisiin is most often found in scientific or descriptive contexts, such as biology, histology, dermatology, or other disciplines where pigmentation is a relevant trait. It is one of several inflected forms of pigmentoitunut, contrasting with other cases like pigmentoituneet (nominative plural “pigmented”) or pigmentoituneita (partitive plural), each serving different grammatical roles in a sentence. The form shows how Finnish adjectives and participles agree with the noun in number and case, while the illative plural suffix reflects directional meaning.

Etymology and construction: pigmentoitunut comes from pigmentti (pigment) plus the verb-forming elements that yield a past participle meaning “pigmented.” The adjectival ending -inen combines with the participle to form pigmentoituneinen/pigmentoitunut, and the illative plural suffix -isiin (or corresponding allomorphs) marks the directional illative plural, yielding pigmentoituneisiin in standard usage.

Related terms include pigmentoituneet (pigmented, nominative plural) and pigmentoituneet solut or pigmentoituneisiin soluisiin depending on the sentence structure. While not a standalone concept, pigmentoituneisiin serves as a precise grammatical form for referring to groups of pigmented entities in Finnish text.
