Below are listed the names given to the poetic feet by classical metrics. The feet are classified first by the number of syllables in the foot (disyllables have two, trisyllables three, and tetrasyllables four) and secondarily by the pattern of vowel lengths (in classical languages) or syllable stresses (in English poetry) which they comprise.
The following lists describe the feet in terms of vowel length (as in classical languages). Translated into syllable stresses (as in English poetry), 'long' becomes 'stressed' ('accented'), and 'short' becomes 'unstressed' ('unaccented'). For example, an iamb, which is short-long in classical meter, becomes unstressed-stressed, as in the English word "betray".
