Answer:
The word "clothe" in this excerpt means "to cover".
Step-by-step explanation:
The term "cover" means "to stretch out over something," thus in the phrase "That clothe the wold and meet the sky," means "It stretches out over the world and meets heaven." You can see that the exchange of words does not change the meaning of the phrase and still establishes a relationship of cohesion and coherence with the text.
