Understanding Perfective and Imperfective Aspect in Mandarin

What is Grammatical Aspect?

Grammatical aspect in languages like Mandarin refers to how actions, events, or states are viewed concerning time. It indicates whether an action is completed or ongoing.

Perfective Aspect in Mandarin

The perfective aspect, represented by 了 (le), implies that an action is completed. In Mandarin, it modifies the verb to signal that the action has reached its endpoint. This aspect is contextually different from the past tense, which merely indicates when an action took place without specifying its completion.

Usage of '了' (le)

The particle 了 is often used after the verb to indicate the perfective aspect. It shows that the verb's action is complete, regardless of whether it happened in the past.

Imperfective Aspect in Mandarin

The imperfective aspect, on the other hand, emphasizes ongoing actions or states without focusing on their beginning or end. In Mandarin, this is often expressed using the particles 在 (zài) and 着 (zhe).

Differences between '在' (zài) and '着' (zhe)

在 (zài) is primarily used for actions currently taking place, akin to the present progressive tense in English. In contrast, 着 (zhe) is used to describe a state that is continuous or habitual, often after stative verbs.

• 在看书 (zài kàn shū) - She is reading
• 开着 (kāi zhe) - The door is open
