Best practice

Use "contains only" to clearly define the exclusive contents of something, avoiding ambiguity about what else might be included. For example, "The recipe contains only five ingredients."

Common error

Avoid using "contains only" when the list is not exhaustive. For example, instead of saying "The basket contains only apples, oranges, and bananas" when other fruits are also present, use "The basket contains apples, oranges, and bananas, among other fruits."
