To show possession using an apostrophe, add ’s for individuals (“Smith’s car”) and just the apostrophe after the s for plurals (“the Smiths’ car,” “the Martinezes’ dog”). By convention, names from classical mythology and the Bible ending in s show possession with the apostrophe only (“Jesus’ teachings”).

An apostrophe followed by an “s” is used in English to create possessive nouns. For example, the noun dog becomes dog’s when you refer to something belonging to the dog, such as “the dog’s ball.” With plural nouns ending in “s,” you add the apostrophe after “s” and do not add an additional “s.”

Once you've determined whether you need to make a possessive, follow these rules to create one. add 's to the singular form of the word (even if it ends in -s): the owner's car James's hat (James' hat is also acceptable. For plural, proper nouns that are possessive, use an apostrophe after the 's': "The Eggleses' presentation was good."

Apostrophes are used in possessive nouns to indicate that something belongs to something or someone else. To indicate possession with a singular noun, add an apostrophe “s” ’s at the end of the word. This also applies to names and other proper nouns.
