Which of the following is a correct pair of singular and plural?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Circus : Circuses
Plural of nouns ending in -s:
Nouns that end in -s take -es in the plural. Circus comes from Latin, but it does not keep a Latin plural in -i. It takes the regular English -es. So circus → circuses.
Why the Other Options are Incorrect?
Option 1: Bonus : Boni — Incorrect. Bonus also comes from Latin, but it takes the regular English -es, not -i. Bonus → Bonuses.
Option 3: Potato : Potatos — Incorrect. Potato is one of the nouns ending in -o that take -es. Potato → Potatoes.
Option 4: Wife : Wifes — Incorrect. Wife changes -fe to -ves in the plural. Wife → Wives.
