Possessive Forms

Possessive forms can be confusing.
Possession means that something belongs to someone. Possessive forms show ownership in the English language.
In many other languages, possession is shown by using the word "of." (Example: The car of the man.) In English, possession is shown using a possessive form of a word. (Example: The man's car.)
