Bob Yates: No reply is really too late. Grammar remains useful in study of any language. Unfortunately, I have quite a number of college students, whose use of English grammar is weak. I question whether these weak users will do much for the language development of future pupils in Texas or elsewhere in the land. When returning any kind of written work, I still circle errors. This simple move seems to be effective in some cases. Richard Swerdlin ([log in to unmask])
