When one toasts someone or something, one raises one's glass. That is metaphorically "to the sky".
Student or Learner
For this sentence:
"Now he slunk around the environs as the revelers raised their cups to the sky and shouted toasts in an unfamiliar dialect."
what does "raise something to the sky" mean? Is it a figure of speech?
