Collins COBUILD English Grammar Fourth Edition, Fourth edition

I do love this book. Sincerely. Loads of examples and usage notes/tips, quite a few sections with differences between BrE and AmE, that's gorgeous.Well, the text printed has become a bit pale.

Good book, good quality. Just waiting for a long time.

Lo compré para mi hijo, profesor de inglés viviendo fuera de USA, para ayudarlo en su trabajo.
