Which of the following is an idiom?

• A. In The Long Run
• B. Orange Juice
• C. Two Nouns
• D. Washing Machine

Answer: (A)

An idiom is a phrase whose meaning isn’t obvious from the individual words. Here, the expression “in the long run” conveys a sense of outcomes over time, meaning “eventually” or “over a long period,” rather than describing a literal run that is long. It’s a fixed expression people use to talk about results that appear after some time.

The other options are literal or descriptive phrases with straightforward meanings: orange juice is a beverage, two nouns describes a grammatical idea, and washing machine is a concrete appliance. They don’t carry a figurative meaning beyond their parts.
