Where does the word 'structure' refer?

• A. ways a dictionary is assembled.
• B. organization of alphabetical entries.
• C. components, or parts, of words.
• D. places, or institutions, that house books.

Answer: (C)

The word structure in this context points to the internal makeup of a word—the components that form it, such as roots, prefixes, and suffixes. Thinking of “unbelievably,” you break it down into un- (prefix) + believe (root) + -able (suffix) + -y (suffix). This focus on how a word is built from parts is what “structure” means here.

The other options describe external arrangements or places (how a dictionary is assembled, how entries are ordered, or where books are kept), not the internal linguistic makeup of a word.
