If it were about a business named "AlabamaJacks" then " AlabamaJacks' " would be appropriate. The example below shows that the proper spelling would be " AlabamaJack's " since it's about a product that belongs to "AlabamaJack". hehe, God I hate this stuff! My head still hurts where the teacher used to whack it! BIP!, Nat! How many times do I have to tell you!
Forming possessives of nouns
To see if you need to make a possessive, turn the phrase around and make it an "of the..." phrase. For example:
the boy's hat = the hat of the boy
three days' journey = journey of three days
If the noun after "of" is a building, an object, or a piece of furniture, then no apostrophe is needed!
room of the hotel = hotel room
door of the car = car door
leg of the table = table leg
Once you've determined whether you need to make a possessive, follow these rules to create one.
