“Streetwise” often refers to having practical knowledge and skills for navigating urban environments, especially in areas or situations that require a heightened awareness of people, places, and potential risks. It means understanding social cues, being resourceful, and knowing how to handle yourself in different situations, especially in cities where things can be unpredictable.
Someone who is streetwise might know how to avoid trouble, pick up on the intentions of others quickly, or have a sense of where to go (or not go) at different times of day. It can also involve knowing the cultural nuances and unspoken rules of an area to make safe and smart decisions.
