Larry Trask, who sadly died a few years ago, was on the faculty of Sussex University and taught Grammar when I studied Applied Language at Brighton University in the mid-1990s. He was an inspiring teacher. As my course studied all aspects of linguistics, with Brighton's particular interest in automatically generated and translated language, it was essential to have a sound grasp of its underlying structure. I was lucky enough, as a mature student, to have been educated in an age where we were taught grammar, although at a far more basic level than subsequently at Uni, whereas the 'traditionally-aged' students were at an almost complete loss. Larry dealt with us all, whatever our levels. So I bought Larry's book in his memory. It is sound and detailed, although not as inspiring as the man himself, and covers much more than just grammatical structures, dealing also with sociolinguistic topics. Excellent glossary.
