Etymology
The word comes from the ancient Arabic interrogative kam, meaning how much or how many. Early Arabic philosophers doubled the final consonant to turn this question word into an abstract noun, kamm, meaning quantity. They coined it to translate Aristotle's category of poson, quantity, set against kayf, quality. The same term later gave modern Arabic its word for quantum in physics.
