The term 'streetwise' refers to the ability to handle oneself in a street-smart way, navigating difficult situations with ease. However, not everyone possesses this trait, and there are antonyms to this word. One antonym of streetwise could be 'naive,' which refers to a lack of experience and understanding of the world's complexities. Another could be 'gullible,' which means easily persuaded or deceived. 'Inexperienced,' 'clumsy,' and 'inept' could also be antonyms, contrasting with the idea of being quick-thinking and resourceful. Regardless of which antonym fits best, it's clear that not everyone is streetwise, and it can be a valuable trait in certain settings.
