Hi,
I have to write some paragraphes for my internship file. In the file, can I create a non-indented paragraph like:
XXXXX (title)
XXXXXXXXXXXXXXXXXXXXX (paragraph 1)
XXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXX (paragraph 2)
XXXXXXXXXXXXXXXXXXXXX
Thanks.
Sure.
Yes. In writing papers, paragraphs (spelled with no E!) should have EITHER an indent OR a space - never both.
I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.
Spaces instead of indenting are more and more common nowadays. I haven't indented a paragraph for years.
