Define ‘metaphor’ and give an example.

A metaphor is a figure of speech that makes a direct comparison between two unlike things by stating that one thing is another, without using words such as "like" or "as." This allows for a more vivid and imaginative description, encouraging the reader to see a deeper connection between the two subjects. The example "Time is a thief" illustrates this definition effectively; it suggests that time steals moments from our lives in a way that evokes a strong emotional response, even though time is not literally a thief.

By using this figurative language, metaphors enhance the richness of language and can help convey complex ideas in a relatable manner, making them a powerful tool in literature and everyday speech. The other options represent different literary techniques that do not align with the definition of a metaphor.
