What is the meaning of the word unbelievable as it is used in the following sentence? It is unbelievable to think that a polar bear's fur is not white, but it's the truth! Each hair is a clear tube that reflects the light of the snowy environment.
When they say unbelievable, it means they are surprised, and did not know that yet. And technically, I did not know that either. I hope this helps you on whatever you use(d) it on.
