street smarts

Meaning: The knowledge one needs to live on the streets; less literally, it means knowledge of the way things work in the real world.

Example: “Her street smarts kept her safe during years of travel.”

Origin: American slang, with its earliest documented appearance in the Chicago Daily Defender in 1966, describing the practical, hard-won survival knowledge and social savvy that comes specifically from real, direct experience navigating an often difficult urban environment, rather than from formal schooling. The phrase was deliberately built to contrast with "book smarts," academic intelligence gained through study — the two terms together drawing a sharp, commonly recognized line between theoretical knowledge learned in a classroom and practical, adaptive competence earned the hard way, out in the world itself.
