Cretic

A cretic (also Cretic, amphimacer and sometimes paeon diagyios) is a metrical foot containing three syllables: long, short, long. In Greek poetry, the cretic was usually a form of paeonic or aeolic verse. However, any line mixing iambs and trochees could employ a cretic foot as a transition. In other words, a poetic line might have two iambs and two trochees, with a cretic foot in between ( -' -' '-' '- '-).
