How do you write simile and metaphor sentence with explanation?

A simile compares two different things using "like" or "as," while a metaphor directly states that one thing is another. For example, "Her smile was like sunshine" (simile) suggests warmth and brightness through comparison, while "Her smile was sunshine" (metaphor) asserts that her smile embodies the qualities of sunshine itself. Both devices enrich writing by creating vivid imagery and deeper emotional connections. Use them to evoke feelings or paint a clearer picture for the reader.
