I am not Claude Levi-Strauss or Ludwig Wittgenstein, but to make long story short, when i select "world" to describe something, i try to select lowest common denominator, i.e. simplest and most used construct, that known to biggest part of potential recipients. It might not be most exact, historically correct, or most descriptive construct. Its choice we all have to make during our young years, and then stick to it for rest of our lives!

However, I respect your right to use language in any other way!

As result, I always will be using "pyu" over "tircut", Burma over Myanmar, Bombey over Mumbai, etc...
