Covered with wild plants and weeds, or having grown too large.
From Old English 'over' (beyond) plus 'growan' (to grow). The compound literally means 'grown beyond its intended size or tidiness.'
Overgrown places are where nature reclaims human spaces—in just 50 years, a city can become a jungle if people leave it. Chernobyl and Detroit both show how quickly plants and animals take back what we built when we stop maintaining it.
