Siisteydellä

Siisteydellä is a Finnish noun form meaning the state or quality of cleanliness or tidiness. It is derived from the base word siisteys (cleanliness, tidiness) and uses the adessive case, marked by the suffix -llä, to indicate a dimension or aspect of a subject rather than a concrete location. In practice, siisteydellä is often used to discuss cleanliness as a measurable attribute in discussions of standards, quality, or conditions.

In usage, siisteydellä can appear in formal, technical, or evaluative contexts. It can refer to the level of cleanliness of a place, object, or operation, and it is commonly used when comparing or describing standards. Examples include statements about health, safety, or customer perception where cleanliness is a key factor: for instance, “Kodin siisteydellä on merkittävä vaikutus asukkaiden hyvinvointiin” (The cleanliness of the home has a significant impact on the residents’ well-being) or “Ravintolan siisteydellä on suora vaikutus asiakastyytyväisyyteen” (The restaurant’s cleanliness has a direct effect on customer satisfaction).

Relation to other terms: siisteys is the nominative base, while siisteydellä is the adessive form used to frame cleanliness as an aspect or dimension. The concept is closely tied to discussions of hygiene, maintenance, and quality management, and it appears in guidelines, inspections, and evaluative writing.
