Procrastination

拖延

A general economy constraint which states that all movements in a derivation should be delayed as long as possible. An operation should take place only when it is needed, and not before. The procrastinate principle prefers derivations which postpone movements until after spell-out, so that the results of the movements do not affect phonetic form.

表示一条通用的经济制约，即派生过程中所有的移位都应尽量往后推迟。任何一项操作只有在需要时才发生，而不是在此之前。按照这条原则，将各种移位推迟到拼出之后进行的派生过程较为可取，因为这样移位的结果不会影响语音形式。
