#Roman military
- Alae — The plural form of the feminine noun 'ala'; in ancient Roman military history, it designates multiple auxiliary cavalry or infantry units placed on the army's flanks; in anatomy and zoology, it represents the prominent symmetrical wings or structural formations of certain bones, organs, or insects (such as alae sacrales or the nasal wings). This structural term of morphological precision describes paired lateral elements that ensure aerodynamic balance, skeletal stability, or mechanical protection of an anatomical opening.
