rentgenowskiej

Rentgenowskiej is a grammatical form of the Polish adjective rentgenowski, used to express relation to X-rays or radiography. Specifically, rentgenowskiej is the feminine singular genitive, dative, or locative case of the adjective, and it appears when describing a feminine noun in those cases. For example, in phrases such as techniki rentgenowskiej (of X-ray technique) or o rentgenowskiej technice (about X-ray technique), the ending -iej/ -kiej indicates the feminine form in the appropriate case.

The base adjective rentgenowski (masculine), rentgenowska (feminine nominative), and rentgenowskie (neuter/plural) are commonly used to describe things related to X-ray imaging, radiography, or radiology. The form rentgenowskiej therefore serves to agree with feminine nouns in grammatical roles that require a genitive, dative, or locative case, ensuring correct sentence structure in Polish.

Etymologically, the term derives from rentgen, the Polish adaptation of the surname Röntgen, after Wilhelm Röntgen, who discovered X-rays. The root rentgen- is combined with Polish inflectional suffixes to form adjectives that denote a relation to X-ray technology. This vocabulary is standard in medical, scientific, and technical contexts in Polish.

In usage, rentgenowskiej appears in descriptions of methods, equipment, or findings involving X-ray techniques when the modifying noun is feminine. It is not a proper noun and is written in lowercase unless it begins a sentence or part of a title.
