Caesura is a trait of verse rather than prose, yet it is not limited to poetry alone. Characters in theatre, particularly in William Shakespeare's plays, frequently converse in verse, and their lines may contain caesurae. In fact, many words that are not part of verse but which occur in poetic lines need to be distinguished from non-poetic words that have the same spelling and sound; these include such items as prepositions, conjunctions, and articles. Cesuras are important in poetry because they give rhythm to the poem and attract readers' attention. Without them, poems would be dull and uninteresting. However, too many cesuras can make a reader feel like leaving the room, so they should be used wisely. In addition to being useful for attracting readers' attention, caesuras can also highlight particular parts of speeches or lyrical passages. He then goes on to describe how her eyes sparkle like diamonds and his heart beats fast like a drum until finally he dies. The use of caesuras here helps to create a dramatic effect by showing us what Romeo feels at this moment, and we can imagine what is going through his mind as he speaks.
