Saying an English sentence with a listing or sequence of several terms, there will always be a comma in between each term and it will end with an "and" before the last term.
My question is, should there be a comma before the "and" as well? That is, is this correct:
I have this, this, this, and this.
or is this correct:
I have this, this, this and this.
I have seen the first version with an ending comma often. This is very different from my native language (Danish, where the second sentence structure would always without exceptions be the only correct one.) Thus I am would like to have made clear what the grammatical rules are and if it must or can be included.
I am quite sure that there should be no comma before "and" in a sentence of just two terms, like:
I have this and this.
So, how is the correct use and rule of the last term in a sequence of several (more than two) terms in a sentence?
What happens if a Danish writer breaks a grammatically strict rule? Are they exiled to England? – Edwin Ashworth Jun 20 '15 at 23:13
