Mental ability, intelligence, or intellectual capacity; the power to think and solve problems.
Compound of 'brain' and 'power' (from Old French 'poeir' meaning ability). 'Brainpower' treats intelligence as a kind of energy or force, similar to physical power.
The term 'brainpower' exploded in popularity during the Industrial Revolution and has become even more common in our 'knowledge economy.' It reflects our modern belief that thinking ability is as valuable as physical labor—a radical shift from agrarian times.
