A paragraph (from the Greek paragraphos, “to write beside” or “written beside”) is a self-contained unit of a discourse in writing dealing with a particular point or idea. A paragraph consists of one or more sentences . Though not required by the syntax of any language, paragraphs are usually an expected part of formal writing, used to organize longer prose.

This is what a successive paragraph looks like. Some people prefer a space between paragraphs, while others prefer sucessive paragraphs indented with no margins between them.
