dipody

dipody, in classical prosody, a pair of metrical feet that is taken as a single unit. Trochaic, iambic, and anapestic verse are all measured by dipodies. In them a monometer consists of one dipody (or two feet), a dimeter of four feet, a trimeter of six feet, and a tetrameter of eight feet. When trochaic or iambic verse is measured by single feet it is called tripody (three feet), tetrapody (four feet), hexapody (six feet).
