讹转是一种语言的误用。以修辞法而言，系明显打破语言通同规范的手法（通常为蓄意）。另见飞白。英语catachresis源自希腊语κατάχρησις，意思是「不当使用词汇」。

讹转常用于情绪激动或丧心病狂的写照，尤其显见于巴洛克文学及达达主义、超现实主义者文学。

例如：

该文本来应该是「devastated（被蹂躏）」的地方误用了「decimated」（衔接的动词和副词不匹配）。

Catachresis (from Greek κατάχρησις, "abuse"), originally meaning a semantic misuse or error—e.g., using "militate" for "mitigate", "chronic" for "severe", "anachronism" for "anomaly", "alibi" for "excuse", etc.—is also the name given to many different types of figure of speech in which a word or phrase is being applied in a way that significantly departs from conventional (or traditional) usage.
