Kosmosissa

Kosmosissa is a Finnish adverb meaning “in the cosmos” or “in space.” It is the inessive form of the noun kosmos, which denotes the cosmos or universe. In Finnish grammar, the suffix -ssa (or -ssä) marks location inside something; thus kosmosissa literally translates to “inside the cosmos.”

Usage: The term describes a location or state of being inside space and appears in scientific writing, fiction, and poetic prose. While avaruudessa is the more common everyday word for “in space,” kosmosissa carries a more formal or lyrical tone and is often used to evoke vastness, mystery, or cosmic scale.

Context: Kosmosissa can appear in discussions of astronomy, cosmology, or space exploration, as well as in metaphorical expressions about humanity’s place in the universe. It is less frequent in casual dialogue but is recognized by Finnish speakers as a correct, if somewhat elevated, term.
