This grammar is for anyone who is interested in the English language and how it works. Many people will come to this book because they are learning English and trying to master the structure of the language. As soon as they have enough practical English to master the text, they will find this grammar helpful to them although it has been written primarily for students of advanced level. | The job of preparing the lists has been one of the most interesting and challenging problems in the preparation of this book. The computer does the first stage, and produces a fist by searching out all the words that fit a pattern it is given. For example, it might be asked to pick all the words that end in '-ing' and do not have a corresponding form without the '-ing'. The first list it produces includes such words as 'overweening', and 'pettifogging', which are not very common, and which in our view can be left to a later stage of language learning. Also found are 'blithering' and 'whopping', which have a special function and are treated in a separate paragraph . A few words fit the pattern well but are only found in very restricted combinations, or collocations. 'Piping' goes with 'voice', and 'gangling' goes with 'youth' or 'boy'. Since grammar mostly deals with generalities, we feel that it could be misleading to print them in fists which are intended to encourage composition.
