The articles - D5 What’s difficult when using the articles in English! Vietnamese don’t have something like that, therefore I always feel confusing when choosing which one between definite article, indefinite article and no article. I know we use the/a definite article when we imply that the listener knows the identify of noun’s referent. Sometimes, I want to stress on quantity of noun like “A tree is not a forest”, but this sentence is obvious. Can I use the article like that? And why? Pls help me explain this confusing and correct my entry.
