Over the last two decades, governments and companies around the world have been encouraged to implement plain English in order to communicate essential information in letters, documents, reports, contracts, and forms in a more clear and understandable way. The Quick Reference Plain English Guide is a practical guide that explains how to write, and communicate information clearly. It provides guidance on how to write better letters, memos, instructions, legal documents, and reports to avoid being obscure, long-winded, and prone to jargon. This guide teaches how to write plain English using 20 easy-to-follow guidelines covering plain words, sentence length, active and passive verbs, punctuation, grammar, planning, and good organization of points. Writing myths are also explored and controversially exploded, such as 'You must not start a sentence with but', and 'You must not split your infinitives'.
