Answer:
The words are allegorical.
Step-by-step explanation:
An allegory is the occurence of the same letter or sounds in a string of closely connected words. The sentence shows a pattern that is allegorical.
This can be seen in the use of stern, and sad which both begin with S. The next group of words which are darkly meditative, distrustful, and desperate, all begin with the letter, d. They also have similar sounds.
