Final answer:
The metaphor 'the witch broke out in chandeliers of sweat' is used to vividly describe the witch's intense sweating in a luxurious and decorative way, like a chandelier.
Step-by-step explanation:
In Ray Bradbury's novel Something Wicked This Way Comes, the metaphor “the witch broke out in chandeliers of sweat” compares the witch's intense perspiration to luxurious and decorative chandeliers. This vivid description emphasizes the intensity and perhaps the nervousness or fear that the witch is experiencing. It conjures an image of excessive and possibly sparkling beads of sweat cascading down, reminiscent of the grandeur and the clustered illumination one would expect from a chandelier.
