- For Teachers
I'm not trying to tell you whose opinions you must accept. I was just pointing out that everyone is expected to acknowledge the sources of their phrases/sentences/texts if they are quoting. No more, no less.
Please be aware that I'm neither a native English speaker nor a teacher.
If that is an excuse for recommending structures that no careful user would accept, then so be it!
I have fully answered the original question and have nothing further to add.
