Also known as: 了1, verb 了, completed action 了 and perfective aspect 了.
The particle 了 (le) has a lot of uses. One of the most common is to express the completion of an action. This is called aspect, which is not the same as tense. Tense is about when an action happens: past, present or future. Aspect is about whether the action is complete in a certain time frame.
- Le is the pinyin romanization of the uncommon Chinese surname written 樂 in traditional characters and 乐 in simplified ones (Lè, lit. "happy", "happiness"). It was the 81st of the Song-era Hundred Family Surnames, but is not currently among the top hundred surnames in mainland China or on Taiwan.
