What compares two unlike things using words such as like as than and because?

A simile compares two unlike things using the Words "like" or "as." For example, saying "Her smile is like the sun" directly compares the brightness of her smile to the sun. While "than" can be used in comparisons, it is typically found in comparative adjectives rather than similes. The phrase "because" is not used for comparisons but rather to explain reasons.
