replace recent mistakenly uttered text
The lo'ai ... sa'ai ... le'ai replacement construct asks the listener to replace the text after lo'ai with the text after sa'ai. The order sa'ai ... lo'ai ... le'ai is also allowed, and either or both parts can be omitted and thus left up to context. When both parts are omitted, the word le'ai on its own indicates that a mistake was made while leaving all the details up to context. It is also possible to attach SAI to a le'ai construct: le'ai dai (or le'ai da'oi ko'a) indicates that someone else made a mistake; le'ai pei asks whether someone else made a mistake; and sai, ru'e and cu'i can be used to indicate the importance of the substitution. Furthermore, le'ai nai can be used to explicitly deny mistakes instead of acknowledging them (compare "sic").
