Also known as: 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 whatever time frame we're talking about.

The Basic Pattern

To indicate completeness with 了, the structure is:

Subject + Verb + 了 + Object

Notice that 了 goes directly after the verb. This 了 is called verb 了.

Example Sentences

Some basic examples:

  • 他 上 飞机。 "He got on the plane."
  • 我 喝 五 瓶 啤酒。 "I drank five bottles of beer."
  • 你 到 北京 没有? "Have you arrived in Beijing?"

The examples above indicate a completed action, but they might also seem very similar to a "past tense" in English. To illustrate that 了 can also indicate that one action is completed before another, see the following examples:

  • 你 吃 完 以后,来找我。 "After you've finished eating, come look for me." (future action)
  • 你 到 以后,给 我 打电话。 "After you have arrived, call me." (future action)
  • 明天 我 吃 晚饭 以后 就 跟 朋友 去 咖啡店。 "Tomorrow after I've eaten dinner, I'll go to a cafe with friends." (future action)

As you can see, 了 can appear in sentences about the future as well as the past. What's important is whether or not the action has been completed, no matter what time we're talking about. This also means that verb 了 can't be used with habitual or continuous actions.
