Question

Select the correct plural noun from the singular form of the noun:
The police need _____ to close the cases (proof).
a)Proof
b)Proofs
c)Proof’s
d)None of the above.

Answer 1

Hint: The word takes up a regular plural noun.

Complete step by step answer:
The word ‘proof’ is a noun that does not take up an irregular plural noun i.e. the plural form of the noun does not change substantially from the singular form of the noun. Therefore, the plural noun of the word ‘proof’ is ‘proofs’. It is one of the words that only adds ‘s’ in plural rather than ‘ves’. Some other words include ‘roofs’. So, the sentence can be completed as follows: The police need proofs to close the cases. Hence, option b is the correct option.

‘Proof’ is the singular form of the word. Therefore, option a is an incorrect option. The word ‘proof’s’ is incorrect because apostrophe is used to show something belonging to someone. Therefore, option c is an incorrect option.

Note: Keep in mind that apostrophe is never added to a plural noun.
