Hienorakeisista

Hienorakeisista is a Finnish inflected form derived from the adjective hienorakeinen, meaning fine-grained or finely textured. It is used in noun phrases to describe materials or substances that have small particle sizes, and it appears in the elative plural case, indicating “from the fine-grained ones” or “of the fine-grained materials.” In practice, the form is common in technical and scientific Finnish, especially in geology, soil science, and materials science.

In usage, hienorakeisista commonly accompanies nouns such as aineksista (components), sedimentteista (sediments), or maalajeista (soil types) to specify the fine-grained nature of the referenced material. For example, phrases like hienorakeisista aineksista or hienorakeisista sedimentteista convey information about materials characterized by small particle sizes.

Context in science and industry often associates fine-grained materials with particular physical properties, such as lower permeability and higher plasticity, compared with coarse-grained materials. Fine-grained sediments typically include fractions like silt and clay, which influence sedimentology, soil classification, and engineering considerations.

Etymology and grammar notes: hienorakeinen is formed from hieno (fine) and rakeinen (grainy). The ending -ista in hienorakeisista marks the elative plural, used with a following noun in a sentence to express origin or composition. Related terms in Finnish include hienorakeiset (the fine-grained ones) and phrases describing specific fine-grained materials.
