My students were working with opposites the other day and we decided to look up the word black which also led us to bleach (not a likely pair for present meaning) but there is a definite link I think. My question is, What is the base or root of these words - I thought 'bhel' but then wondered if 'bl' would be it. And then thought I was completely off track. Help!
We also discovered the original meaning for the much loved Oreo biscuits while we were on this mission. Not a pleasant finding!
