Can someone please explain what is difference between having a comma and not having a comma in front of "and".
I would like to have A, B, C, and D
I would like to have A, B, C and D
If my examples above are not quite right, please use a suitable example to make your point.
And is used like this
A, B, C,
When Its working as Conjuction Connecting two Independent clauses.
Whereas A, B, C and D is used to represent the list of things etc.
