Use a period to indicate that your sentence or unit is complete:
The hamburger is the winner.
Possessive nouns also show a connection between two nouns.
Let’s take a look at the noun Anna and the noun hula hoop.
If you add a period, you would indicate that the sentence is
complete — that someone or something is doing an action. That
someone or something would be the subject that is performing
the action of a verb. Is Anna performing an action? No, Anna
is not connected to a verb. The verb is missing. The possessive
noun Anna’s only indicates a relationship between the two
nouns. As shown by the apostrophe, the hula hoop belongs
to Anna.
Anna’s hula hoop represents a building block. It is not a unit,
because a unit must contain a subject and a verb, and this has
no verb. However, you can use this possessive noun to create
a unit.
Expanding units to include other ideas is the next step to take.
And remember that it’s easier to enlarge units when you know
where to find the subject.
We will now take a big step by learning what objects can do.
