| 释义 | 〔purty〕Purty is probably the most common American example of metathesis, a linguistic process in which two adjacent sounds are reversed in order.Metathesis in English often involves the consonantr and a vowel, since the phonetic properties ofr are so vowellike. For example,the wordthird used to be thrid, and bird, brid. By the same process,Englishpretty often came to be realized as purty in regional speech. Most such words stabilized because of the influence of printing and the resultant standardized spelling,butpurty for pretty has survived in regional American dialects. Purty 可能是美国换位词最普遍的一个例子， 换位是两个相邻的音在顺序上调换位置的语法过程。英语中的换位经常包括辅音r 和一个元音， 因为r 的语音属性是非常像元音的。 举个例子来说，单词third 过去曾是 thrid 及 bird和brid。 具有同样的过程，英语单词pretty 在区域性语言中常被渐渐地认作 purty。 大部分这样的单词固定下来是因为印刷的影响以及由此而产生的标准化拼写，但是代替pretty 的 purty 却在美国区域性的方言中存在下来了 |
