Change of state with "le"
- Also known as: 了2, change-of-state 了, sentence 了 and modal 了.
了 (le) has many uses. You probably first learned 了 (le) as a particle that tells you an action is completed, which is also known as "了1." However, this article is not about that use of 了 (le); instead, it is about indicating a change of state (了2). In other words, there is now a new situation, or there is about to be a new situation. This whole "change of state" idea can take numerous forms, and this page includes some helpful examples.
When used in this way, 了(le) is placed at the end of the sentence to show that the whole statement describes a new situation.
