Determine the items in your list. The kind of information you're presenting in your list will help you decide on a format.
Separate the items in your list using a comma if it's a simple list. This means that each item is a single unit, such as "English, African and Middle Eastern history."
Add semi-colons to create your list if each unit contains commas already. For example, you might be listing one item as "tough, opinionated Americans," another as "somber, dignified Europeans" and a third as "ambitious, loyal Japanese." In this case, each item in the list should be separated with a semi-colon: "tough, opinionated Americans; somber, dignified Europeans; and ambitious, loyal Japanese."
