<h3>What is an irony?</h3>
An irony is a state of affairs or an event that seems deliberately contrary to what one expects and is often wryly amusing as a result. An irony is also a literary device, originally used in Greek tragedy, through which the essence of a character's words or actions is clear to the audience or reader although unknown to the character.
