What is a simile and metaphor?

Simile and Metaphor are both classified under

"Figures Based on Similarity" :-

A) SIMILE  :- A simile is the expression of an detailed resemblance between  two objects which are originally dissimilar in nature. The resemblance between those two things must be distinctly stated with "like", "as", "such", "so", etc.

Eg:-The child shows the man, as morning shows the day.(J.Milton)

B) METAPHOR :- By this figure of speech, a word is transferred from the object to which it properly belongs to another object in such a way that a comparison is implied, though not formally expressed. High suggestiveness is a special characteristic of a good metaphor.

Eg:-He is the pillar of his state.

[ Footnote :-   A metaphor differs from a simile only in form and not in substance. The point of resemblance is clearly stated in a simile whereas in a metaphor it is just hinted or implied.

Red as a rose is she   -   Simile

A rose is she               -   Metaphor

A metaphor can be expanded into a simile. Similarly, a simile can be condensed into a metaphor. Hence, a metaphor is an implied simile.  ]
