Student or Learner
I was taught that if I want to write about 3 kinds of object, I should structure my sentence in this way:
e.g. I have apples, oranges(,) and watermelons.
However, sometimes during my reading, I encounter sentences like this:
The first day they were very active, pottering aboutwith hammers and nails and red calico, to put up cur-tains, make their house habitable and pretty; resolvedto settle down comfortably to their new life.
(From Joseph Conrad's "An Outpost of Progress")
Is such usage grammatical?
Thank you very much!
