Technically, an apostrophe is used in word shortcuts and possession or sense of ownership. However, this article focuses on the apostrophe ‘s’ and the rules to consider. We must always remember that there are strict rules in using apostrophe + ‘s’ because once you’ve put the apostrophe in the wrong position, it is already considered the wrong grammar. It is on a case-to-case basis. Don’t worry, let’s tackle the rules for the apostrophe ‘s’ systematically.

  1. A person or object possesses/own something; singular

    a. The noun ends with a consonant or vowel letter = noun + apostrophe + ‘s’


      Randy’s bag is so full of candies.

      Ryan’s crush is Faith.

      Rose’s cheeks are so red!

      Ryan Smith’s hair is shiny. (put the apostrophe + “s” after the complete noun)

      This is my nephew’s pajamas. (put the apostrophe + “s” after the noun)

b. The noun ends with the letter ‘s’ = no need to put ‘s’, only apostrophe


      Lass’ hands are dirty.

      James’ backpack is empty OR James’s backpack is empty.

Note: since it is a singular noun (ONLY) ending with ‘s’, putting apostrophe and ‘s’ after the noun is considered!

c. The noun ends with “ch” or “z” = noun + apostrophe + ‘s’


            Brach’s doll is lost.

            James Brich’s ex-lover has a new lover.

            Grez’s venue for her 18th birthday is at the beach.

2. A group of people possesses/own something; plural

a. The noun ends with a consonant or vowel letter = noun + apostrophe + ‘s’


            The children’s book is excellent for learning.

            The band’s theme is sensational!

b. The noun ends with the letter ‘s’ = no need to put ‘s’, only apostrophe


      The Chases’ house is near the café. (Chase = last name of the family; specific plural noun)

      The kids’ trousers look color gray from afar.

      The boxers’ hands are weary.

c. The noun ends with the letter “ch” or “z” = plural form of the noun + apostrophe


            Branches’ thorns are growing from time to time.

            The Waltzes’ car was damaged because of the accident yesterday.

3. Expressions


            For Heaven’s sake!

            Oh for goodness’ sake!

Let’s go now!

It is not complicated to use this set of rules, however, it must be always considered. Remember, once you’ve put the apostrophe in the wrong position based on the rules, it is already the wrong grammar.
