Hi again.
I have a doubt. Can I use comma in a list of three or more before ¨and¨ or ¨or¨?
example:
The pilot took with him a flashlight, a bottle, and a pencil for the trip.
The pilot took with him a flashlight, a bottle, and a pencil
In a list of three or more, will the comma will be always before the or or and?
Thank you
