The Importance of Regular Plural Nouns in English

There are hundreds of regular plural nouns in English. You simply add an S or E S for most words. But you know what I'm going to say now, there are irregular plural nouns. So try and say the plural before me. Man. Men. Woman. Women. People. Here's one more. Child. Now this might sound basic but many students of English, including students at advanced level, sometimes forget and make mistakes with these plurals. They're very important words.
