Hello respected English teachers,
Could you please explain when to use comma before 'and' and when not in a sentence?.
"He likes apples,peaches, and mangoes."
"He likes apples,peaches and mangoes"
Please explain the difference if both are correct. And please some examples of the both.
Both are correct. That comma is called the serial or Oxford comma.
The choice is one of style, not grammar. Just be consistent in how you use it, putting it in one sentence, but not the next.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
