Metaphor is a figure of speech which makes an implicit, implied or hidden comparison between two things or objects that are poles apart from each other but have some characteristics common between them. In other words, a resemblance of two contradictory or different objects is made based on a single or some common characteristics.
In simple English, when you portray a person, place, thing, or an action as being something else, even though it is not actually that “something else,” you are speaking metaphorically. “He is the black sheep of the family” is a metaphor because he is not a sheep and is not even black. However, we can use this comparison to describe an association of a black sheep with that person. A black sheep is an unusual animal and typically stays away from the herd, and the person you are describing shares similar characteristics.
Furthermore, a metaphor develops a comparison which is different from a simile i.e. we do not use “like” or “as” to develop a comparison in a metaphor. It actually makes an implicit or hidden comparison and not an explicit one.
1. My brother was boiling mad. (This implies he was too angry.) 2. The assignment was a breeze. (This implies that the assignment was not difficult.) 3. It is going to be clear skies from now on. (This implies that clear skies are not a threat and life is going to be without hardships) 4. The skies of his future began to darken. (Darkness is a threat; therefore, this implies that the coming times are going to be hard for him.) 5. Her voice is music to his ears. (This implies that her voice makes him feel happy)
