How it's used
Literary in nature, this term is rarely used in casual daily conversation and is mostly reserved for formal writing, historical accounts, or news reports describing geographical obstacles. It carries a sense of grandeur and historical weight, often implying that the barrier is difficult to overcome or cross. When used in speech, it sounds quite dramatic or academic.
Examples
The Yangtze River acts as a natural barrier, hindering transport between the two banks.

Common phrases
the natural barrier of the Yangtze River
Common mistake
Learners often mistake this for a common word for any river or ditch, but it specifically refers to a formidable, wide, or deep natural barrier that serves as a defensive line. Using it to describe a small stream or a simple canal would sound unnatural and overly poetic.
