飞白，又名“非别”、“拟误”，是指明知其说错或写错而将错就错，有意如实记录（指说话人由于口音或文化水平的关系读白了音、写白了字，用“飞白”以存真）或援用（指说话人或作者有意读白、写白以谐趣）下来的修辞方式，分为语音飞白、字形飞白、语义飞白和句子飞白四种。运用飞白能逼真地刻画人物形象并产生幽默讽刺的效果。

与飞白（语音飞白）类似的英语辞格是malapropism（误用词语）， 是指有意或无意误用发音相似而意义不同的词语，从而增添语言的趣味性和幽默感。例如(徐鹏1996):

"Ernest，" said Theobald, from the arm-chair in front of the fire, where he was sitting with his hands folded before him, "don't you think it would be very nice if you were to say 'come' like other people,instead of 'turn'？"

"I do say ' turn'，"replied Ernest, meaning that he had said 'come'. (Samuel Butler，The Way of All Fresh)

此例中幼小的Ernest舌位不对，发音不准，将come误说成tum，十分生动真实地记录了他的讲话神情。从修辞效果来讲，下面的译文是相当到位的：

“欧内斯特，”西奥博尔德说，他这时正把两手交抱在胸前，坐在炉火前面的一把安乐椅上。“你不认为要是你跟别人一样说‘去’，而不要说‘器’，那听起来会让人舒服多了吗？”

“我是说的‘器’”欧内斯特回答说，意思当然是说，他说的是“去”。 (黄雨石译）

曹雪芹在《红楼梦》中常常有意运用“飞白”手法来刻画人物性格， 渲染场景气氛，从而推动故事情节的发展。首先，我们从语音飞白的修辞效果及其翻译谈起。

1) 二人正说着，只见湘云走来，笑道：“爱哥哥，林姐姐，你们天天一处顽，我好容易来了，也不理我一理儿。”黛玉笑道：“偏是咬舌子爱说话，连个‘二’哥哥也叫不出来，只是‘爱’哥哥‘爱’哥哥的。回来赶围棋儿，又该你闹‘么爱三四五’了。”……湘云笑道：“这一辈子我自然比不上你。我只保佑着明儿得一个咬舌的林姐夫，时时刻刻你可听 ‘爱’呀‘厄’的去。阿弥陀佛，那才现在我眼里！”（第二十回）

杨译：

"Why，Ai Brother and Sister Lin!" she cried cheerfully. "You can be together every day, but it's rarely I have a chance to visit you; yet you pay no attention to poor little me. "

"The lisper loves to rattle away," said Daiyu with a laugh. "Fancy saying ai instead of er¹(注 1. Er means"two" or "second" and ai "love") like that. I suppose, when we start dicing，you'll be shouting one，love, three，four, five …"

...

"Naturally I'll never come up to you in this lifetime. I just pray that you'll marry a husband who talks like me，so that you hear nothing but 'love' the whole daylong. Amida Buddha! May I live to see that day!"
