What is the difference between "men" and "man" in English grammar?

[IRORafael8]

Can someone explain how "man" and "men" are used differently in English? I'm a bit confused about when to use each one.

 

[jgvhka]

The difference between “man” and “men” is singular vs. plural:

• Man – refers to one adult male.
  
  • Example: “The man is reading a book.”
• Men – refers to two or more adult males.
  
  • Example: “The men are playing soccer.”

In short: “man” = singular, “men” = plural.

There is a singular form of man, one male adult and the plural form of man and this is men, which means more than one. LastName: That man is tall (sing). Those men are tall (plural).
