Rhetoric

When we speak a language, knowingly or unknowingly we always tend to play with the language. Same is with the english language. In our day to day life we use rhetoric and thus play with the language. Rhetoric in the sense using the figures of speech.  Examples of  Simile, metaphor and also examples of personification are the most commonly used, be it intentionally or the otherwise.

In order to make you understand about these uses let me provide you with some examples of these figures of speech. Starting with simile, it is a figure of speech which is used to compare two unlike things mostly using the words such as "like" or "as". Following are examples of simile:

He fights like lion
She is as clever as a fox.

Metaphor is another figure of speech which is also used to compare two unlike things but without using like or as. Following are examples of metaphor:
The salesman was a shark.
His teeth are white pearls.
Many poets also use extended metaphors. The poem mother to son by Langston Hughes is an extended metaphor example.

Personification is that with which we personify something. As for example:

The house is looking cheerful.
My computer is acting strange.

So these were some examples of figures of speech. Hope this piece of knowledge will serve you as helpful.
