Mostly we add "s" to the noun to mean it as plural, but not for all of them. Is there any rule for adding s / es / some thing else. I mentioned few words for Understanding.
Eg : Dog - Dogs Knife - Knives bus-buses.
And i also have a doubt, should i mention Plural or Plurals. Which is correct. Eg : Plural of Nouns ? / Plurals of Noun ?
