Similes and metaphors are as easy as pie
A simile is part of speech that expresses similarity. It uses the as-adjective-ascomparative form, or sometimes with like.
Due to the odd spelling and pronunciation of the word, ‘sɪmɪli’, one of my students once asked me what a smiley was. It took me a few moments to figure out what he meant.
A metaphor normally uses the verb to be and is more figurative language.
Where a simile is a figure of speech that can say someone is like or similar to something, a metaphor says someone is something.
