Question

Exercise 2 Write the plural of each word. proof

Answer 1

The plural of the noun proof is prooves.

In general, to form the plural of a singular regular noun, we must add an s at the end of the word:

• dog → dogs
• house → houses
• girl → girls

However, there are some exceptions, depending on the letter with which the noun ends.

When the singular noun ends in -f, we drop the -f and add -ves to form the plural.

This is why the plural of proof is prooves.

Other examples of plurals of nouns ending in -f are:

• Thief → thieves
• calf → calves
• half → halves
