Quiz: Remember the definition of mal de mer?
Old English tigele "roofing shingle," from West Germanic *tegala (cf. Old High German ziagal, German ziegel, Dutch tegel, Old Norse tigl), a borrowing from Latin tegula "tile" (cf. Italian tegola, French tuile), from tegere "roof, to cover" (see stegosaurus). Also used in Old English and early Middle English for "brick," before that word came into use. The verb meaning "to cover with tiles" is recorded from late 14c.
