Definition:
Puns are a very popular literary device wherein a word is used in a manner to suggest two or more possible meanings. This is generally done to the effect of creating humor or irony or wryness. Puns can also refer to words that suggest meanings of similar-sounding words. The trick is to make the reader have an “ah!” moment and discover 2 or more meanings.
