docens

Docens is a Latin term formed from the verb doceo, meaning "to teach." In grammar, it is the present active participle and translates roughly as "teaching" or "instructing." It may be used as an attributive participle (for example, docens magister) or, less commonly, as a substantive noun referring to a teacher or instructor, especially in medieval and classical Latin texts. The standard forms are declined like other participles: singular nominative docens, genitive docentis, dative docenti, accusative docentem, ablative docente; plural nominative docentes, genitive docentium, dative/docentibus, accusative docentes, ablative docentibus. The participle agrees with gender and number in Latin.

Historically, docens appears in texts describing education, tutoring, and instruction, sometimes in phrases such as docens magistrum (the teacher who teaches) or magister docens (the teacher who instructs). Beyond Latin, the word has influenced modern terminology: in English, docent is used for a university lecturer in parts of Europe and Asia, and for a museum guide in some English-speaking contexts. The term docens itself does not carry a specialized technical meaning in contemporary science and is primarily encountered in Latin-language studies, philology, or discussions of classical education.

In summary, docens primarily denotes "one who teaches" in Latin as both a participle and a noun, with its legacy visible in related terms such as docent in modern languages.
