iustarum

Iustarum is a Latin word-form: the genitive plural feminine of the adjective iustus, meaning “of the just” or “of the righteous.” In Latin, adjectives agree with the nouns they modify; thus iustarum accompanies feminine nouns in the genitive plural and, when used substantively, can refer to “the just ones.”

Etymology and morphology: it comes from iustus, with the feminine genitive plural ending -arum. It appears in phrases where justice or righteousness is attributed to a feminine-noun head, for example iustarum rerum (“of the just things”) or iustarum legum (“of the just laws”). The form signals a relationship of possession or description and can function in various grammatical roles depending on the surrounding noun.

Usage: iustarum is found in legal, philosophical, and ecclesiastical Latin, especially in medieval and Renaissance texts, where discussions of justice, righteousness, or rightful law occur. It is not a standalone English term but a Latin inflected form encountered when reading Latin sources.
