Pesuihin

Pesuihin is a Finnish grammatical form. It is the illative plural of pesu, a noun meaning washing or cleaning. The form is used to express movement toward or into washing processes or places, such as a laundry facility or a stage in a workflow that involves washing. In general Finnish usage, pesuihin appears primarily in written, technical, or instructional texts and is less common in casual speech.

Etymology and morphology: The base pesu combines with the illative plural suffix to yield pesuihin. Like other illative plural forms in Finnish, pesuihin marks direction into a location or process rather than a standalone noun. The form illustrates how the illative case operates in plural contexts, indicating movement into the concept of washing rather than toward a specific object.

Usage: Pesuihin is typically found in contexts describing procedures, production lines, or laboratory or industrial settings, where it helps specify steps or locations in a sequence. In everyday conversation, speakers are more likely to use paraphrases or different constructions depending on the sentence, rather than relying on this specific form.
