Question

Fester Addams went shopping for these party supplies streamers balloons and confetti.
where should add the semicolon or coma

Answer 1

The sentence can be punctuated correctly with a comma to separate the items in the list. Here's a correctly punctuated version:

"Fester Addams went shopping for these party supplies: streamers, balloons, and confetti."

The colon after "supplies" introduces the list of items, and the commas separate the items in that list.
