A simile is a figure of speech that compares two things using the words "like" or "as." For example, "Her smile is like sunshine." In this simile, the speaker is comparing the woman's smile to sunshine.

A metaphor is a figure of speech that compares two things directly, without using the words "like" or "as." For example, "Her smile is sunshine." In this metaphor, the speaker is saying that the woman's smile is sunshine.
