It is usually necessary to know how new forms are pronounced and written and what their role in grammar is. Sometimes teachers think that their students already know certain words from past courses but certainly they do not, so teachers must make sure that they know what their students know before introducing new items, because sometimes they will discover that there are a lot of new items for the
