Positions, Locations, and Capabilities

Positional Words. Positional words such as '上', '下', '里', and '外' are used after nouns to indicate specific directions or locations. Mastering these markers is vital for describing spatial relationships, identifying where objects are placed, and providing clear environmental context with authoritative precision.

Preposition '在'. The preposition '在' (zài) is the primary tool for indicating where an action occurs. When used before a verb, it establishes the location of the event, forming a critical structural component for describing daily activities and professional responsibilities with linguistic clarity.

Modal Verb '能'. The modal verb '能' (néng) is used to express physical ability, circumstantial possibility, or permission. It is a versatile tool for describing what is feasible within a specific context, allowing speakers to communicate their capacities and negotiate permissions with authoritative tone.
