Astronomilise

Astronomilise is an Estonian adjective form meaning "of astronomy" or "astronomical." It is the genitive singular form of the common adjective astronomiline, used to describe nouns in contexts that require a genitive modification or to form compound expressions related to astronomy. The base form astronomiline corresponds to the English “astronomical” or “relating to astronomy.”

In usage, astronomilise appears when the noun it modifies is in the genitive or part of a possessive-like construction. For example, astronomilise observatooriumi töö translates roughly as the work of the astronomical observatory, and uuringud astronomilise valdkonna probleemide kohta means studies concerning problems in the field of astronomy. The form is a standard inflected variant within Estonian grammar, preserving agreement with the noun it describes.

Etymology traces astronomilise to the Estonian adjective astronomiline, derived from the Greek roots astro- (star) and -nomia (law or study) and borrowed into Estonian through European languages. It shares cognates with other languages’ words for astronomy, such as the English “astronomical.” The Estonian system uses inflection to mark case and number, so -ilise in the genitive singular is a common ending for adjectives of this class.
