This is wonderful. Thank you all for your insight!
I get what you mean, Retro, about people not envying... The reverse side of that, if you like, is the hesitation or embarrassment one has about correcting a friend's work...it's difficult to do that without suspecting the person (being corrected) thinks they're being patronised.... so I simply have to put that to one side and merely correct away.
Ben, thank you for the advice....
I have actually procured a copy of an excellent book published for proof-readers and copyeditors. (Nobody knows why in the profession, the first term is hyphenated, but the second term isn't, and is written as one word!) It not only gives correct spelling to awkward words, but whether certain terms should be italicised, accented or carry capital letters in some instances but not others (such as 'government, and Government....). It's an excellent book.
I very much appreciate the support from everyone, and Retro, am starting on your document, today.
