What does fenestral mean?
Fenestral is a formal adjective meaning relating to windows or window openings. It derives from the Latin fenestra, meaning window, the same root that gives us defenestration, the act of throwing someone out of a window. In architecture, the word describes anything pertaining to windows — their placement, openings, or treatment — as in discussions of a facade's fenestral arrangement. In anatomy and medicine it takes on a related but distinct meaning, describing structures associated with a fenestra, a small natural opening such as those found in the inner ear or in certain bones. Because it is technical and comparatively rare outside specialist fields, fenestral lends writing a precise, professional tone; it appears most often in architectural criticism, building conservation reports, and anatomical literature rather than casual conversation.

Etymology of fenestral
Fenestral comes from the Latin fenestra, meaning window or opening, likely via French fenestral or directly from Medieval Latin. The root also underlies fenestration, the arrangement of windows on a building, and defenestration, the act of hurling someone from a window — famously associated with the Defenestrations of Prague. Its anatomical use arose from the application of fenestra to small openings in bone and other tissue.
