dummy
word
Definition
A dummy can be a model of a person used for display, practice, or testing. It can also mean something fake or temporary, and in informal speech it can be an insulting word for a stupid person.
Usage & Nuances
Very context-dependent. Common uses include 'a crash-test dummy', 'a dummy version', and 'dummy data'. As an insult ('Don't be a dummy'), it sounds childish or old-fashioned and can be rude. Don't confuse it with the British meaning of 'pacifier'.
