What is grammar?
Grammar is the system of a language. People sometimes
describe grammar as the "rules" of a language.
Do we need to study grammar to learn a language?
If you are serious about learning a foreign language, the
answer is “yes”. Grammar can help you to learn a language
more quickly and more efficiently. It's important to think of
grammar as something that can help you, like a friend.
