Having no limits or constraints; extending indefinitely or infinitely. Can refer to physical space, mathematical functions, or abstract concepts like imagination or potential.
Formed by adding the prefix 'un-' to 'bounded' in the 14th century. The mathematical sense of extending to infinity developed alongside advances in calculus and analysis in the 17th-18th centuries, while metaphorical uses expanded in literature and philosophy.
Unbounded doesn't always mean better - while unbounded creativity sounds wonderful, research shows that some constraints actually boost innovation by forcing us to think more cleverly within limits!
