When multiple items contain commas
Suppose items themselves include commas:
- Use semicolons to separate list items:

Using conjunctions with commas
In complex sentences with multiple conjunctions, commas help delineate separate ideas clearly:
- He bought apples, which were fresh; bananas, which were ripe; and oranges, which were sweet.
Proper order when listing multiple categories
When mixing different kinds of descriptors, ensure consistent order and punctuation, but this goes beyond simple comma rules.
