This week, I am going to leave you with a reference to a site; namely: Major Comma Uses.
Some of us have the tendency to use commas excessively, whereas others among us hardly ever resort to them. While we have to keep in mind that the concept of poetic license does indeed exist, it does not give us a license to kill written English.
The site in question also offers a valuable insight into other language areas, such as “Parts of Speech”, “Sentence Structure” and “Usage”, and provides “Exercises”. Should you decide to review them, you could always come back to see if my text here follows the standard rules . . .
