A caesura is a pause or break in a line of poetry, often used to create a dramatic or rhythmic effect. It can occur anywhere within the line and is not necessarily marked by punctuation, serving as a tool for poets to manipulate the flow and emphasis of their verse.
A metaphor is a figure of speech that directly refers to one thing by mentioning another, providing a symbolic comparison that enhances understanding or adds meaning. It is a powerful linguistic tool that influences perception, thought, and communication by creating connections between seemingly unrelated concepts.
