The weather report uses bitterly cold to describe tomorrow’s weather.
The word use dates back to the 1800’s when, instead of describing a sour taste, bitter became figurative for hard to accept or endure, intensely grievous, and cruel. When used to describe the feeling associated with a bitter thing, writers use bitterly when they mean stinging.
Yes, all of the above. The bitter cold coming our way (when I was hoping for daffodil shoots and warm breezes) means we stay inside. The wind howls, and at this very moment, I can hardly see through the swirling storm. If I have to leave the house, I’ll wrap up in multiple layers so no cold can sting me.
I feel battle ready.
