A caesura (/siːˈʒjʊərə/ or /sɪˈʒʊrə/, pl. caesuras or caesurae; Latin for "cutting"), also written cæsura and cesura, is a break in a verse where one phrase ends and the following phrase begins. In time value this break may vary between the slightest perception of silence all the way up to a full pause. A caesura in music represents a similar break or pause. The length of a caesura where notated is at the discretion of the conductor. In choral works a brief caesura may be notated where singers are to catch their breath.
In classical Greek and Latin poetry a caesura is the juncture where one word ends and the following word begins within a foot. In contrast, a word juncture at the end of a foot is called a diaeresis. Some caesurae are expected and represent a point of articulation between two phrases or clauses. All other caesurae are only potentially places of articulation. The opposite of an obligatory caesura is a bridge where word juncture is not permitted.
In modern European poetry, a caesura is defined as a natural phrase end, especially when occurring in the middle of a line. A masculine caesura follows a stressed syllable while a feminine caesura follows an unstressed syllable. A caesura is also described by its position in a line of poetry: a caesura close to the beginning of a line is called an initial caesura, one in the middle of a line is medial, and one near the end of a line is terminal. Initial and terminal caesurae are rare in formal, Romance, and Neoclassical verse, which prefer medial caesurae.
