Quote:2.N-UNCOUNT Bother means trouble or difficulty. You can also use bother to refer to an activity which causes this, especially when you would prefer not to do it or get involved with it.
• I usually buy sliced bread – it's less bother.
• The courts take too long and going to the police is a bother.
Hi, the quoted is excerpted from my dictionary about "bother".
1. would anyone explain the difference in the meaning between bother and trouble?
2. Can I replace "bother" with "trouble" in the example sentences I quote above?
3. Since "bother" is defined as uncountable, I wonder why it goes with "a" for "a bother".
Thank you!
