Definition:
Similes are one of the most commonly used literary devices; referring to the practice of drawing parallels or comparisons between two unrelated and dissimilar things, people, beings, places and concepts. By using similes a greater degree of meaning and understanding is attached to an otherwise simple sentence. The reader is able to better understand the sentiment the author wishes to convey. Similes are marked by the use of the words ‘as’ or ‘such as’ or ‘like’.
Example:
He is like a mouse in front of the teacher.
