This is an antique car, a woodie, at the National Park Service in San Francisco. The back of the car is made of wood, hence the nickname woodie. If you are wearing a sweatshirt with a hood, you are wearing a hoodie. If you want something sweet to eat, you want a goodie. Well, you probably want more than one goodie. You want goodies.
An antique is generally valuable because it is old. I have antique jewelry from my mother, aunt and grandmother and antique furniture from my grandmother. Now think about what you have that is old. Do you have antique jewelry, trinkets or furniture? If you do, do you value these antiques because they are old or because someone in your family gave them to you?
