Answer:
Tetrameter is a line composed of four feet per line.
Step-by-step explanation:
In poetry, a tetrameter is a verse of four feet, very used in English poetry, in particular. Variations exist between these different feet, which determine different forms of tetrameters. It occurs in trochaic, iambic and anapestic rhythms, both catalectic and akatalectic, depending on whether the last foot is shortened (catalectic) or complete (akatalectic) by one syllable.
