Poetry Guide: Amphibrach
Amphibracs are seldom used to construct an entire poem. They mainly occur as variants within, for instance, an anapaestic structure.
In English, stress-based poetry an amphibrach is a stressed syllable surrounded by two unstressed syllables. It is the main foot used in the construction of the limerick. E.G. "There was a | young lady | of Wantage"
The amphibrach is also often used in ballads and light verse. E.G. the hypermetrical lines of Sir John Betjeman's Meditation on the A40
