Opakeita

Opakeita is the Finnish partitive plural form of the adjective opakea, meaning opaque. It is used to describe multiple objects that do not transmit light clearly. Because Finnish adjectives decline to agree with the nouns they modify, opakeita appears when the modified noun is in the partitive plural. For example, opakeita aineita means opaque substances, and opakeita materiaaleja means opaque materials.

Etymology and use: The root opakea denotes lack of transparency; opakeita follows the standard pattern for partitive plural adjectives, formed from the stem opake- plus the -ita ending. The form is common in technical writing about materials, optics, and in everyday descriptions of objects that block light or appear nontransparent.

Context and related terms: Opakeita is typically encountered in phrases describing plural items rather than as a standalone noun. Related concepts include opakeus (opacity) and the Finnish term for transparency, läpinäkyvyys. In scientific and educational contexts, opakeita helps distinguish objects or substances that are not see-through from those that are transparent or translucent.

Usage notes: Opakeita functions as a descriptive modifier; its English gloss depends on the noun it modifies (for example, opaque substances, opaque windows). The form is a grammatical inflection, not a separate lexical item.
