Etymology: "Sweetums" is "sweet" with the suffix "-ums" added. That suffix is found in playful, affectionate coinages such as "wisdoms" and "buttums," where it turns an ordinary adjective or noun into a pet name for a person. Adding it to "sweet" produces a term of endearment, used to address someone the speaker is fond of.
