avaruudellisessa

Avaruudellisessa is a Finnish adjective form meaning space-related or cosmic, derived from avaruus, space or cosmos, and the suffix -ellinen. The base form is avaruudellinen, and avaruudellisessa is the inessive singular form used after a noun, for example in avaruudellisessa ympäristössä (“in an outer-space environment”) or avaruudellisessa tutkimuksessa (“in space-related research”).

The word can function attributively, as in avaruudellinen tutkimus (“space-related research”), or predicatively, as in se on avaruudellinen (“it is space-related”). It is commonly used in scientific, educational, and literary contexts to describe phenomena, objects, or concepts tied to outer space or cosmic origins. In everyday Finnish, it helps distinguish topics that concern space from those that are purely terrestrial.

Nuances and related terms: avaruudellinen is often contrasted with kosminen, which is more specifically related to cosmology or the universe as a whole. Avaruudellinen can also describe environments or conditions associated with space, such as avaruudellinen ympäristö or avaruudelliset ilmiöt. In technical language, other compound forms appear, for example avaruudelliset tutkimukset or avaruudellisiin ilmiöihin viittaavat teoriat, depending on case and number.

See also: avaruus, kosminen, avaruustutkimus, kosmologia. The term reflects Finnish usage of space-related terminology across science, education, and culture, maintaining a neutral, descriptive tone.
