Hi, whats the difference in "the book is red, green and blue" and the "book is red, green ,and blue."
Mainly that comma before "blue". Does that make a difference?
That comma does not make much of a difference in your examples. In fact, many publications do not use that comma before "and," which comma is commonly termed the "Oxford comma."
However, in certain instances that comma does make a difference.
Consider the following examples.
Yesterday, I visited my friends, John Smith and Nisha Sud.
Yesterday, I visited my friends, John Smith, and Nisha Sud.
The first one conveys that "I" visited friends, and that the two friends visited were John Smith and Nisha Sud.
The second conveys that "I" visited a list of people, the list including not only friends, but also John Smith and Nisha Sud.
Of course, if you were to mean the second but write the first, your meaning would not be clearly conveyed.
So, in some cases, cases like the one above, that comma matters.
