Reversal

颠倒

(1) A term used by some psycholinguists to refer to a type of tongue-slip where two linguistics units are interchanged. Traditionally, such errors are referred to as metatheses or spoonerisms.

(2) A term used in metrical phonology for the switching of weak and strong nodes encountered in such phrases as thirteen men, so that ~// becomes /~/; also known as iambic reversal, the rhythm rule, or the thirteen men rule. The metrical grid, as a consequence, has a structure which is altering rather than clashing.

（1）有些心理语言学家用来指一类舌头打滑的口误，即两个语言单位互换位置。传统上这类口误称作换位或斯波纳现象。

（2）节律音系学术语，指thirteen men“十三人”这类短语中弱节点和强节点换位，结果~//变为/~/，也称作抑扬颠倒，节奏规则，或十三人规则。颠倒的结果是节律栅的结构呈交替状而不是抵触状。
