 * has two basic uses, one of which is as a modal particle and the other is as an aspect particle.
 * As a modal particle, 了 mostly appears at the end of a sentence, which is used to mark the occurrence or "happening" of an event. Compare the following two instances of dinner completion:

 * With 脫 here the speaker establishes the current state of the phone "having been lost", without presenting this as a change of state as 脫了 would.
