Key Differences
Additional implies an increase in number or quantity, adding more to what is already present, like additional resources. On the other hand, supplementary often refers to something added to improve or complete a set, such as supplementary information.
The use of additional is common when the added items are not necessary for the function of the original set, like additional toppings on a pizza. Whereas, supplementary items are typically necessary or beneficial for completeness, like a supplementary textbook in a course.
Additional can sometimes be interchangeable with extra, suggesting that the additions could be optional. In contrast, supplementary carries the connotation of filling a gap or providing support, like supplementary exercises in a workout routine.
In contexts like budgeting or planning, additional might refer to unexpected or unplanned increases, such as additional costs. Supplementary, however, would more likely refer to planned enhancements that are meant to augment the original plan, like supplementary funding for a project.
Additional often implies more of the same type, while supplementary suggests variety or diversification, providing something different that complements the original.
