I'll let you in on a little secret. It's a myth that all or even most EFL or ESL teachers love grammar. A lot of them don't even understand most of it when they first begin teaching. As someone said to me when I was starting out, ''The trick is to stay one exercise ahead of the students.'' Now decent lesson planning does take a bit more preparation than that, but I regularly ''learn'' grammar rules just a day or two before I teach them for the first time. The problem isn't that I don't know what you say in English, but that I don't know how to explain why it's correct in a simple way my students will understand. Enter Murphy.
