Than or As When using than or as, consider the implied words. Annie likes Ben more than him. Therefore, the pronoun after than is the object of the implied verb likes. Annie likes Ben more than he. Use who for the subject of a clause.
Possessive Case Use the possessive case to show ownership.
Mr. McMillan bought his overcoat on sale. The children lost their new gloves. Use the possessive case as the subject of a gerund. Their flying to Nashville was my suggestion. I am not responsible for your failing the test.
