Królewskiej

Królewskiej is the feminine singular form of the Polish adjective królewski, meaning "royal" or "kingly." It is used to modify feminine nouns and appears in several cases in Polish grammar. The base form królewska corresponds to the nominative singular; królewskiej is the form used in genitive, dative, and locative singular.

In usage, królewskiej appears in sentences when describing a feminine noun in the affected case. For example, in the genitive phrase historia królewskiej rodziny (the history of the royal family), królewskiej marks the feminine noun rodzina in genitive.

These inflected forms are common in literature, history, and descriptions involving royalty or royal institutions.

Etymologically, the word derives from król (king) with the standard Polish adjectival suffixes, forming królewski/królewska/królewskie with appropriate inflections. The term is not a proper noun itself but a regular descriptive adjective that adapts to gender, number, and case of the noun it modifies. In Polish, awareness of the feminine singular inflection królewskiej helps distinguish grammatical cases and ensures correct agreement in sentences referring to royal-related subjects.
