This book doesn’t concentrate on what we English teachers (yes, I confess I am one) call descriptive grammar - the kind where you circle all the nouns and draw little triangles around the prepositions. A closely guarded English-teacher secret is that you don’t need to know any of that terminology (well, hardly any) to master grammar. Instead, English Grammar Workbook For Dummies concentrates on functional grammar - what goes where in real-life speech and writing.
