In 1 sentence explain how to use an apostrophe to show possession for singular and plural nouns and to form contractions

Answer 1

Use an apostrophe followed by an "s" to indicate possession for singular nouns (e.g., the dog's leash) and for plural nouns that do not end in "s" (e.g., the children's toys), and just add an apostrophe after the "s" for plural nouns that do end in "s" (e.g., the dogs' park), while also using it to form contractions by replacing omitted letters (e.g., don't for do not).
