säikeiden

Säikeiden is the genitive plural form of säie in Finnish, meaning fiber or thread. As a grammatical form rather than a distinct concept, säikeiden is used to indicate possession or association with multiple fibers, for example in phrases describing materials, fabrics, or biological structures. It is common in Finnish technical and scientific writing to appear as part of larger noun phrases.

In textiles and materials science, säikeiden appears in discussions of fibers within yarns, fabrics, or composite materials. Terms such as säikeiden vahvuus (strength of the fibers) or säikeiden suoruus (straightness of fibers) illustrate how the form functions inside compound expressions describing fiber properties, processing, or quality control. The usage signals reference to more than one fiber rather than a separate concept.

In biology and biochemistry, säikeiden is used to refer to fibrous structures such as cytoskeletal filaments and extracellular fibrous networks. Finnish texts may include phrases like säikeiden polymerointi (polymerization of filaments) or säikeiden järjestäytyminen (organization of fibers), where the genitive plural marks a discussion of multiple filaments or fiber bundles.

Origin and usage: säie denotes fiber or thread, and säikeiden is its genitive plural form. This grammatical function makes säikeiden a frequent component of technical terminology in Finnish, spanning textile engineering, materials science, and biology. Related forms include säie (singular) and säikeet (nominative plural).
