Here are the main reasons why people hate grammar:
Let’s address these points one by one.
There’s some truth to this first objection. There are times that you don’t want any grammar. If you’re doing “hit and run” language learning—learning enough of a language to feel comfortable as a tourist, grammar will definitely slow you down. You want to use the “listen and repeat” method to learn those vital polite phrases. This method can bring you to a respectable conversational level as well. The folks at Berlitz have shown that, given time and enough exposure to a language, you can get some very impressive results.
That’s correct. Children are the ultimate “listen-and-repeat” learners. However, you aren’t five years old any more. Learning a language as a child is very different from learning a second language after your first language has become “burned in.” At that stage in your life, grammar, if presented properly, becomes a terrific learning tool.
