The expansion of viewpoints on the "principal of rhetoric", has brought changes in the inserted contents (headings) of the rhetoric.
In the "Jorjany" definition of rhetoric, "commencement and pause" do not find their proper place, because the discussion of "commencement and pause" here is solely limited to wheather to bring or not to bring the connection "vav".
In the Jorjany's predecessors defintion from "thetric", the "commencement and pause". has a very important place, it's because "commencement and pause", is totaly conformed with their view point of "seperation and union", and this is the very title that some experts know it as the identical and perfect rhetoric.
Although, the main part of "commencement and pause" is done with the use of "syntactics", but the act of pause in the proper location and start from the desired point, is considered as a rhetorical action, because, the topic is about rhetoric speech, and trying to express it, is one of the absolute nessecities of rhetoric.
There are some locations in the "Holy Quran", which are not evolved from syntactic nessecities resulting from "Quran' s special rhetoric" (certain Quranic rhetoric), and these location are the very intervals.
