Use metaphor and simile to bring imagery and concrete words into your writing. This phrase does not mean that the lead singer is literally a salamander. Simile A simile is a statement where you say one object is similar to another object. It is an easy way to attach concrete images to feelings and character traits that might usually be described with abstract words. You don't suddenly produce better poems if you replace all your similes with metaphors, or vice versa.
Concrete words describe things that people experience with their senses.
A person can see orange, feel warm, or hear a cat. Abstract words refer to concepts or feelings. A person can't see, touch, or taste any of these things. As a result, when used in poetry, these words might simply fly over the reader's head, without triggering any sensory response. Therefore, if the poet uses such a word, the reader may take a different meaning from it than the poet intended.
