Why is grammar important?

Just take a look at the cover of this magazine about celebrity Rachael Ray. The text says:“Rachael Ray finds inspiration in cooking her family and her dog”

Of course, what the sentence is supposed to mean is that Rachael finds inspiration in her dog, her family and her cooking. Instead, the sentence sounds like Rachael likes to cook her family and her dog for dinner!

Good grammar can save you from misunderstandings like that. Grammar involves a set of rules you use to form sentences in any language. Grammar rules tell you things like why you walk slowly (not “slow”), and when to say “they” or “them.” Without grammar, it would be very difficult to understand each other.

So learning English grammar is important, but it’s not always easy to start. Where can you get all the information you need, and how can you all of the rules (and the exceptions to these rules)?
