This isn't a question, pal.
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
