A pun is a play on words which usually centers on a word with more than one meaning or the replacement of a homonym that changes the meaning of the sentence for humorous or rhetorical effect. It is produced by using a word that suggests two or more meanings or by exploiting similar sounding words having different meanings. The ambiguities arise mostly in homophones and homonyms. Humorous effects created by puns depend upon the obscurities words involve. 

For instance, in a sentence “A happy life depends on a liver”, liver can refer to the organ liver or simply the person who lives. On the contrary, in a famous saying “Atheism is a non-prophet institution” the word “prophet” is used instead of “profit” to produce a humorous effect.

    • No matter how much you push the envelope, it'll still be stationery.
    • A backward poet writes inverse.
    • The batteries were given out free of charge.

What is a Pun in Poetry

A pun is a play on words created on the similarity between two words, usually in their sound or spelling. It is a joke that plays on the many meanings of a word, or on two words that sound the same. By playing with the words, the writers reveal their cleverness and the shrewdness of their characters. Novelists make use of pun to add humor, or sometimes, the author exploits the double meaning of words in order to add uncertainty or make a statement. 

Apart from being witty and humorous, puns add intense meanings to texts and shape the way in which the text is interpreted by the readers. Besides, puns in a literary works act as a source of comic relief or an intended effort on the part of the writer to show his/her creative ability in using language. Puns can be a fun and witty way to make a piece of literature more light-hearted. It helps to clarify a situation and make the reader think about it in a different way usually while providing a quick laugh. 

For example, here’s a well-known pun
“When a vulture flies he takes carryon luggage.” In this pun, the words “carrion” and “carry on” are homonyms; humans take “carry on” luggage when we fly on planes, while vultures eat “carrion” and may take it with them when they fly.

A pun is roughly defined as a play on the sound of words to achieve a certain effect.
In other words, a pun can:
    1. Make you think
    2. Make you laugh
    3. Increase clarity when we’re trying to determine the meaning of a text
    4. Introduce ambiguity
