In Emily Dickinson's "The Brain Is Wider than the Sky," the poet compares the brain to the sky and the sea. What word would be the best substitution for "brain" in order to help understand the analogy?

"mind"

Explanation:

You could replace "brain" with the word "mind". This is a synonym for "brain" but it refers to the element of a person that enables them to be aware of the world and their experiences, to think, and to feel; the faculty of consciousness and thought, or a person's intellect, whereas "brain" could refer to the physical brain. Using the word "mind" would help you to understand the analogy, as Emily Dickinson is referring not to the physical state of the brain, but the intellectual state of the brain, often called the mind.
