The term 'Swift Quality' can be broken down into two words, WIT and IRONY. WIT is a three-letter word that refers to the ability to use language to create humor or clever remarks. It is often used in literature, comedy, and conversation. IRONY is a five-letter word that refers to the use of words to express something different from and often opposite to their literal meaning. It is often used to create humor or to emphasize a point. Together, these two words describe the quality of being able to use language to create humor or clever remarks while also expressing something different from and often opposite to their literal meaning.
