radicis

Radicis is the genitive singular form of the Latin noun radix, meaning root. In Latin, genitive forms express a relationship of possession or association, so radicis is typically translated as “of the root” and appears in technical descriptions across disciplines such as botany, anatomy, and medicine. The base noun radix belongs to the third declension, with nominative singular radix and genitive singular radicis. The nominative plural is radices, while the genitive plural is radicum.

In botanical and anatomical contexts, radicis is used to form phrases that relate to the root of a plant or organism. Examples include morphologia radicis (“root morphology”) and radicis plantarum (“of the root of the plants”). In anatomy and dentistry, it appears in phrases such as radix nervi (root of a nerve) or radix dentis (root of a tooth), where the genitive radicis links the root concept to the specified structure.

Modern Latin scientific writing continues to use radicis as a standard genitive form to indicate relational meanings tied to radix. It is not typically used as a standalone term; rather, it functions within descriptive nouns and adjectives to specify root-related features.

Related terms include radix, the nominative form meaning “root,” and the adjective radicular. The English derivatives radical and radicle trace back to the same Latin root.
