A specialist in decoration or design; a person whose profession is creating or applying decorative elements.
From Latin decor (beauty, dignity) + -ist (person who practices). This term is a direct variant of 'decorationist,' using the shorter Latin root directly rather than the -ation form.
The existence of both 'decorist' and 'decorationist' for the same profession shows how English speakers experiment with word-building—some prefer short, Latin-direct forms while others like the fuller -ation derivatives. Over time, languages tend to standardize on one, and 'interior designer' eventually won out anyway.
