Siivuin

Siivuin is a term that appears in discussions of Finnish language but is not part of the standard Finnish grammar. The standard first-person singular imperfect of the verb siivota (to clean) is siivosin, and this form is widely used in contemporary Finnish. Siivuin is not listed in most dictionaries or grammars as a standard inflected form. It may occur as a dialectal variation, an archaic or poetic variant, a nonstandard spelling, or a deliberate creative form in literature or language-learning materials.

Because Finnish morphology is highly regular, nonstandard forms like siivuin are often isolated to specific regional speech communities or older texts. If encountered, its meaning, when present, would generally align with “I cleaned” or “I swept” in the sense of completing a cleaning action, but this would be unusual and context-dependent. Without authoritative sources, siivuin should not be assumed to be a normative form.

Siivuin is not known to be the name of a place, organization, or widely recognized concept. It is occasionally used by some writers or learners as a stylistic or experimental element, but such usage does not establish it as an established term in Finnish.
