The word "小淘气" (xiǎo táoqì) is formed as a compound term that combines the adjectival prefix "小" (xiǎo), meaning "little" or "small," with the noun "淘气" (táoqì), which means "mischief" or "naughtiness." Literally, it translates to "little mischief," but it functions as a single, affectionate noun meaning "little rascal" or "naughty child." The structure is descriptive, where "小" softens and endears the inherently playful and mildly scolding term "淘气," resulting in a common term of fond reproach used primarily for children.
