Textual unit or block; a textual paragraph.
This element does not have to be a well-formed paragraph as defined in high school English class, i.e., “a block of text representing a single idea, typographically differentiated from its neighbors”. Rather, the element <p> is a block (as opposed to inline) structural unit which may be only a few words in length.
