Putting the proper article before a noun is really complex. To be frank, I'm still learning this! I don't remember the source, but I had read somewhere that even students of English Literature make mistakes in placing proper articles in their sentences.
Even more confusing is the usage of these articles while describing natural things. I am taught to put the article the for natural things (the sun, the moon, the earth etc.), as they are the only ones.
My question is:
Do we have to place the while describing the natural things like mountains and rivers? And if the answer is no, why? When I talk about Mount Everest, it's the Mount Everest, the only one. It's definite and so the is needed.
Does it have something to do with being 'plural' (as in the range of Himalayas so it's The Himalayas)? But then I watched The Nile on Discovery!
A request: Please point out mistakes in placing articles in this question as well. This'll be the bonus for me! :)
