On the topic of modern Chinese, this paper briefly describes the grammatical characteristics of modal particles with examples.

Modal particles have two grammatical features:

First, it is highly attached and can only be attached to the back of sentences or other words, which plays a certain grammatical role. Secondly, modal particles often express mood together with intonation, so some modal particles can express various moods.

For example, the modal particle "ah" is used at the end of a sentence, which mainly plays the role of delaying the tone, and sometimes it can also play the role of strengthening explanation, reminding and affirmation. For example:

Whoever doesn't want to take part in labor just doesn't have time. (explanation)

This is an old tradition of our army. (Reminder)

Little sister, never mind. (explanation)

You must command the whole company! (Reminder)

They didn't give up. (statement)
