Key Differences
Dummy often denotes a person who does not speak and is used figuratively to describe someone perceived as intellectually inactive, whereas stupid is typically used to describe actions or behaviors that lack intelligence or thought.
Dummy can also refer to a mannequin or a replica used in experiments or for display, while stupid lacks such alternative meanings and focuses solely on describing low intellectual capability or poor judgment.
In colloquial usage, "dummy" might be used affectionately among friends or as a mild rebuke, on the other hand, "stupid" is usually considered more derogatory and offensive when directed at a person.
Dummy is also used in various technical contexts, such as in ventriloquism where it represents a puppet manipulated to appear as talking, whereas stupid has no such specialized applications.
The term "dummy" can function as a noun and an adjective, as in dummy variables in statistics, whereas "stupid" functions as an adjective and a noun, with its usage as a noun being more informal and pejorative.
