Nouns
Nouns aren't marked for anything and if the word can't be used as a noun, then the nominalizer 子 (shi, thing) is used.

Verbs
Some words can be used as verbs. If not, then verbalizers like 乃 (ne, to be), 去 (chu, to do/go) or 付 (tu, to do again) are used.

Verbs are sometimes marked:

Time is never expressed in the verb, but instead is expressed in a temporal clause at the start.

Polarity is expressed in the verb via the particle 不- (hu)

The particle -了 (ri) indicates a finished action, while 正- (sei) indicates the action is going to stop, used without the subject, it's an imperative negative. To make an imperative positive, you use 去- (chu).
