What literary technique is prominently used in Hughes’ line "Does it dry up / like a raisin in the sun?"

In Hughes' line "Does it dry up / like a raisin in the sun?" the literary technique prominently used is a simile. A simile directly compares two different things using the words "like" or "as" to illustrate an idea or evoke imagery. In this case, the comparison of the drying up of a dream to a raisin in the sun evokes a vivid image of something shriveling or losing vitality, enhancing the theme of dreams and aspirations withering over time.

The use of "like" clearly signals that this is a simile, as it explicitly draws a connection between two disparate elements—the abstract concept of a dream and the concrete image of a raisin. This comparison effectively communicates the emotional weight behind the idea of dreams that do not come to fruition, highlighting a sense of loss and disappointment. Understanding this aspect of the line enriches the interpretation of Hughes' work, as it encapsulates broader themes of struggle and the fragility of hope.
