Puhtaisissa

Puhtaisissa is a Finnish grammatical form meaning “in the clean ones” or “in clean places/things.” It is the inessive plural form of the adjective puhdas, used to describe something that is in a state of cleanliness or purity with reference to more than one item or location. In Finnish, adjectives agree with the nouns they modify in number and case, and the inessive case marks location with the suffix -ssa/-ssä. The plural form is created by combining this inessive ending with the plural, yielding puhtaisissa.

Because puhtaisissa is an inflected form, its exact meaning depends on the noun it accompanies. With an explicit noun, it denotes “in the clean…,” for example: puhtaisissa tiloissa means “in clean premises.” When the noun is understood from context, puhtaisissa can function as a standalone phrase meaning “the clean ones” or “the clean things,” though such use is more common in literary or telegraphic style.

Etymologically, puhtaisissa is built from the root puhdas (clean) and follows regular Finnish adjective inflection patterns. The form illustrates how Finnish uses cases and number to express location and quantity on adjectives, not only on nouns.
