shampoo and why?

[Quizmonster]

Speakers of Hindi in India did. It comes from their word, 'capna' meaning to squeeze. (The 'c' has a 's/sh' sound to it.)

So, jno, when Quasimodo washed his hair with shampoo, we have someone with only a resemblance to a real modo using something that only makes a pretense of cleaning hair? Unique concept...
