Anapestic feet consist of three syllables: two unstressed and one stressed. With a sound reminiscent of a horse's galloping, "intervene" and "interrupt" both follow this three-syllable pattern.
Like anapestic feet, dactylic feet are made of three syllables; however, dactylic feet have one stressed syllable followed by two unstressed syllables. This pattern is found in words such as "absently" and "daffodil."
An iambic foot, very musical in its rhythm, is made up of one unstressed and one stressed syllable. The word "employ" is an example of an iambic foot because the second syllable receives the accent. Sonnets often make use of this syllabic pattern.
A trochaic foot occurs when one stressed syllable precedes one unstressed syllable. The words "lover," "railroad" and "singer" are examples. Edgar Allen Poe used trochaic feet in his poem, "The Raven."
There are two kinds of supplementary poetic feet: spondaic, created from two stressed syllables, and pyrrhic, which is made of two unstressed syllables. Neither of these feet are used exclusively, as it would be difficult to write or read a poem written entirely in stressed or unstressed syllables. These feet, therefore, are only used to add variety to lines of poetry.
