In the Buddhist teaching, the word "world" comes from the word "loka", which means "state".

The state can be a mental state or a physical state, depending on the listener.

In Buddhism, there is the following phrase:

The Awakened One, best of speakers,
Spoke two kinds of truths:
The conventional and the ultimate.
A third truth does not obtain.

Therein:
The speech wherewith the world converses is true
On account of its being agreed upon by the world.
The speech which describes what is ultimate is also true,
Through characterizing dhammas as they really are.

Therefore, being skilled in common usage,
False speech does not arise in the Teacher,
Who is Lord of the World,
When he speaks according to conventions.
