When scanning a line of verse, a poet looks at feet as the basic rhythmic unit rather than words. A foot can consist of multiple words and a single word can contain many feet; furthermore, a foot can and often does bridge multiple words, containing, for example, the last two syllables of one word and the first of the next. To scan for feet, one should focus on the stream of sound alone and set aside the actual meaning of the words.
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."
The most common in English verse are the iamb, the trochee, the dactyl, and the anapest.
