Etymology: "Angularis" is the Latin adjective "angularis," meaning "of or belonging to a corner or angle," formed from "angulus" (corner, angle) with the suffix "-aris," which forms adjectives meaning "pertaining to." The root "angulus" is related to Greek "ankylos" (bent, crooked), and it is the source of English "angle" through Old French. In English, the word appears mainly in anatomy, where it describes structures named for their position near a corner or angle of a body part. The most familiar example is the angular artery, which runs near the corner of the eye and the side of the nose, and the angular gyrus, a region of the brain at the angle where the parietal and occipital lobes meet. The Latin term was used by anatomists as they named parts of the body, and the English form carries that same sense of "located at a corner."
