Question

Select the word that can be joined with the given noun to form a compound noun:
Master

• A. Key
• B. Lock
• C. Step
• D. Door

Answer 1

Answer: (A)

Key

Compound nouns are a combination of two nouns in which the first noun is what kind of a person or object it is or what the purpose of the noun is whereas the second noun identifies the first noun.

Example: Newspaper

In the question, the noun given is 'master' which, from the given options, is almost always used with Option A) key. The master key is commonly used and describes a specific object which is the purpose of compound nouns and therefore Option A) is the correct answer.

Option B) lock is incorrect as 'master lock' is never used. Option C) and D) are also incorrect as these two words are normally not compounded with the word 'master'.
