A North American tree of the elm family with edible berries, also called nettletree, known for its resilience in harsh conditions.
From hack (possibly from a Native American language or onomatopoeia) plus berry. The exact origin of hack- is debated, but the plant has been known to English speakers since colonial times.
Hackberry trees are tougher than almost any other tree—they can survive floods, drought, pollution, and salt, which is why they're secretly everywhere in cities but nobody notices them.
