ear (hear also: acou-); Aur‑ denotes the ear structure, especially the external ear (pinna/auricle), or hearing/perception by ear. In clinical contexts, it appears in abbreviations like aur. sin. (auris sinistra, left ear) and terms for ear anatomy, pathology, or procedures, often alongside oto- terms. For example, auricular refers to ear‑shaped or pertaining to the ear, and auriscope is an otoscope for viewing the ear canal.
latinauris; From Latin auris (“ear”), a third‑declension feminine noun with genitive auris and diminutive auricula (“little ear,” auricle). Cognate with Greek ous/ōtos (oto‑), both from Proto‑Indo‑European h₂ṓws (“ear”), explaining the parallel usage in med‑term.
