barbara is as hungry as a horse

Question

is that a simile or a metaphor

 

Answer 1

Your statement is a simile.  However, please remember that a simile is a metaphor, but not all metaphors are similes.  When something is like something else, it is a simile.  A metaphor is often more descriptive or it alludes to the subject with which it is compared.  An example of a metaphor would be "Barbara's stomach growled reminiscent of a starving stallion kept too long in the paddock".

Answer 2

That is a simile because it uses the word "as." Similes must use "like" or "as." That statement as a metaphor would be "Barbara is a hungry horse."
