Etymology

The word "decorator" stems from the Latin "decorare" (to adorn, beautify), combining "decor-" (beauty, ornament) and the agentive suffix "-or," indicating a person who performs an action. The term entered English via French "décorateur," retaining its core meaning of "one who embellishes." In computing, it metaphorically extends to describe a function that "adorns" an object with additional features.
