Astronoomiline
Astronoomiline is a rarely used or coined Dutch adjective that would generally be interpreted as meaning related to astronomers or to astronomy, depending on context. In standard Dutch, the ordinary terms are astronomisch for “astronomical” and astronoom for “astronomer,” with adjectival forms such as astronomische or astronoomische. Because astronoomiline is not widely attested in dictionaries, its exact meaning is not fixed and remains highly context dependent. It may appear in linguistic discussions about neologisms, in historical texts documenting experimental spellings, or in speculative fiction where authors intentionally coin novel terms to evoke a direct link to the noun astronoom.
