What does decorator mean?
A decorator is a person who adorns or embellishes spaces and objects, most commonly as a professional trade. In British English the word typically denotes a painter and decorator — a tradesperson who prepares surfaces, applies paint, and hangs wallpaper inside homes and commercial buildings. In American English it more often refers to an interior decorator, someone who plans and arranges the visual character of a room by choosing colours, fabrics, furniture, and accessories; this role overlaps with but is generally considered distinct from that of an interior designer, who handles structural and spatial planning. The term also extends to specialists such as cake decorators, who finish baked goods with icing and ornamentation. In computing, notably in Python, a decorator is a construct that modifies or wraps a function or class to extend its behaviour without altering its code. Derived from the Latin decorare, meaning 'to adorn', the word shares roots with decoration, decorative, decent, and decorum, all carrying the underlying idea of fitness, propriety, and beauty.
A person whose job is to paint and paper the interiors of buildings; a painter-decorator.
"The decorator arrived early to sand down the woodwork before applying the first coat of emulsion."
This sense is especially common in British English, where 'painter and decorator' is a standard trade title.
A person who decorates something, such as cakes, venues, or Christmas trees, either professionally or as a pastime.
"As a skilled cake decorator, she can turn a simple sponge into an edible work of art."
Standard regular plural; used when referring to multiple people in the decorating trade or profession.
"The firm employs twelve decorators across three regional offices."
The word 'decorator' comes straight from Latin 'decorare', meaning 'to adorn' — the same root that gives us 'decent' and 'decorum', so a decorator is quite literally in the business of making things 'proper' and beautiful.

Etymology of decorator
Decorator derives from the Latin verb decorare, meaning 'to adorn, embellish, or grace', itself formed from decus (genitive decoris), meaning ornament or honour, related to decere, 'to be fitting'. The word entered English in the early 19th century via French décorateur. It shares its root with decorate, decoration, decorative, and, more distantly, decent and decorum, all conveying notions of beauty and appropriateness.
How decorator is actually used
In British English, 'decorator' most commonly means a painter-and-decorator who works on house interiors. In American English this trade sense is less dominant, and the word more often refers to an 'interior decorator' — someone who selects furnishings, colours, and finishes rather than necessarily doing the physical work. The computing sense (as in Python's '@' syntax) is technical jargon within software development only.
