When listing things, it's important to consider the most effective and accurate way to punctuate. By convention, items in a list are usually separated by commas, although words arriving at the end of the list should be separated with an βandβ or an βorβ if appropriate. For example: βI need to buy milk, bread, eggs, and butter.β Using semicolons can be helpful for separating multiple independent clauses, such as in a list of items that require additional explanation. For example: βI need to buy milk, which is low-fat; bread, which is whole-wheat; eggs, which are free-range; and butter, which is organic.β Depending on your needs, other punctuation could be used, such as parentheses or colons. Generally, though, commas are the most widely adopted form of punctuation when listing items.
