What is the difference between 's and s?

Answer 1

If you are asking what is the difference between ending a word in the English language with the letter s and with an apostrophe mark before the s, as this 's, it is the difference between making a word plural and making a word possessive. For example mother can be made to mean more than one mother by adding the letter s to make it mothers. There were several mothers who attended the school meeting. When you place an apostrophe mark before the letter s, you are indicating that the word you have printed, written, or typed, owns something or something belongs to the thing that that word represents. For example, That book is my mother's. (book). This is a simplistic answer, but I think it is adequate for now.

Answer 2

's is a contraction for "is" or "has," while "s" is a pronoun referring to a specific or unknown person or thing.
