astronomicznym

Astronomicznym is the instrumental case form of the Polish adjective astronomiczny, meaning astronomical or relating to astronomy. In Polish, adjectives agree with the nouns they modify in gender, number, and case; astronomiczny becomes astronomiczny m in instrumental singular in many contexts, giving forms such as astronomicznym, astronomiczną, or astronomicznymi depending on gender and number. The phrase zjawiskiem astronomicznym, for example, means “an astronomical phenomenon.”

Etymology and meaning: The word derives from astronomy (astronomia) and the Polish adjectival suffix -iczny, which produces terms meaning “pertaining to.” The base form astronomiczny is used across scientific and everyday language to describe things connected with the science of celestial objects, space observations, and related disciplines.

Usage: The instrumental form astronomicznym appears in constructions where the noun is in the instrumental case, often in predicates of description or when listing objects studied or used in astronomy. Examples include:

- Zjawiskiem astronomicznym jest supernowa. (An astronomical phenomenon is a supernova.)

- Urządzeniami astronomicznymi badamy kosmiczne promieniowanie. (With astronomical instruments we study cosmic radiation.)

- Planetą astronomiczną może być planeta poza większym układem słonecznym. (An astronomical planet could be a planet outside our solar system.) In plural form, the corresponding instrumental forms are astronomicznymi.

Notes: While primarily a grammatical inflection, the term appears frequently in scientific writing, education, and media when describing objects, phenomena, or tools associated with astronomy. It does not denote a separate concept beyond its role as an inflected form of the adjective describing astronomical things.
