A caesura is an abrupt pause in the middle of a line of poetry. Sometimes it serves as a form of punctuation at the end of a phrase or sentence. There are two types of caesurae. A masculine caesura is one that occurs immediately after a stressed syllable while a feminine caesura happens after an unstressed syllable. The caesura is such an important part of poetry that several literary and poetry magazines, such as the University of Delaware's literary magazine, are called "Caesura."
Uses in Poetry
A caesura can create a number of effects depending upon how it's used. Sometimes it simply breaks up a monotonous rhythm and forces the reader to take note of the phrase that precedes the caesura. In other cases, it might be used to create an ominous or dramatic effect. Occasionally, a caesura occurs in the middle of a phrase or sentence of poetry, and in these poems, there are often several caesurae that create their own rhythm.
Effect on Rhythm
A caesura creates a more uneven rhythm than a poem that has no caesura. Masculine caesurae tend to create a more staccato effect in poems, while feminine caesurae are softer and less abrupt. Poets frequently use the symbol "||" to indicate a caesura.
Example of Caesura
Alexander Pope, an 18th century poet who frequently wrote satirical works, used caesurae to add depth to his couplets. For example, in "Eloisa to Abelard," he uses the following set of caesurae: "Alas how changed! || What sudden horrors rise! A naked lover || bound and bleeding lies! Where, where was Eloise? || her voice, her hand, Her poniard, || had opposed the dire command."
