Matterhorn

Alpine mountain, from German Matte "meadow, pastureland" (see mead (n.2)) + Horn (see horn (n.)). So called for its horn-like shape (cut by glaciers in the Ice Ages). The slopes are steep and treacherous; the Matte is for the meadows at its base. The Roman name was Mons Silvius, which might be based on a personal name.
