飞白是故意援误的一种修辞方法，和malapropism相近。

作者模仿、记录或援用某些音近或别音的字词，制造错误以达到喜剧效果等目的。这种作法违反了一般语用的准则，产生弦外之音或幽默特色。

malapropism中文或作麦拉普现象，指文本误用，用语源自英国喜剧作家理查·谢雷登（Richard Brinsley Sheridan）作品《情敌》（The Rivals）中，常常搞错字的Malaprop夫人，该名字取自法语mal à propos，意思是「不恰当」。

A malapropism (also called a malaprop or Dogberryism) is the use of an incorrect word in place of a word with a similar sound (which is often a paronym), resulting in a nonsensical, often humorous utterance. An example is this statement by baseball player Yogi Berra: "Texas has a lot of electrical votes," rather than "electoral votes." Malapropisms also occur as errors in natural speech and are often the subject of media attention, especially when made by politicians or other prominent individuals. The philosopher Donald Davidson has noted that malapropisms show the complex process through which the brain translates thoughts into language.
