Hold on, I am not asking the difference between when to use "the", "a", or "an".
My question is, when to use the. For example:
Do not cross in front of bus;
or
Do not cross in front of the bus;
Similarly,
Check if we can reach target from source;
of
Check if we can reach the target from the source;
Are there some definitive rules about when (and when not) to use the articles (especially the the)?
Me? Well, I have the habit of using (or rather overusing) the article the. Hence the question.
