Is a Line Break Always Inserted to Begin a New Paragraph..??


In my experience, it is best in Word, especially for formal documents and newsletters etc., it is usual to only insert one paragraph mark (as opposed to line break which is ASCII) between paragraphs, but to have the Body Text or whatever paragraph style is used (some style other than Normal) formatted with leading spaces e.g. 6 point.

This makes it easier to tweak paragraphs and spacing as as sometimes necessary, and makes it easier to use the Keep Paragraph with Next and Keep Lines Together properties to properly control your text flow, rather than manually doing it with multiple paragraph marks.

Just my 10c worth.
 
I was taught typing in school on a really old banger of a typewriter and we put a space between each paragraph. We never indented a paragraph either. A colleague of mine indents every single paragraph and I personally think it looks awful.
