The Speak Good English Movement has published a free guidebook to help people speak and write better. Grammar Rules is a pocket-sized book which covers topics in grammar, including tenses and the use of adverbs and conjunctions. It also highlights common English language errors made by Singaporeans and provides the correct words and phrases. SMU School of Social Sciences Associate Professor of Theatre/Performance Studies (Practice) Margaret Chan described the book as a source of useful information about language that should be available to everyone.
