Domain 4 | Inside a List: Commas and Semicolons Between Items

Objective: Correctly punctuate a list of three or more items in a sentence — including verb-phrase and adjective series — always placing a comma before the final item, correctly switching the whole list to semicolons when one item's own wording already contains a comma, and never adding a comma after the very last item.
