IRREGULAR PLURAL FORMS
Some words have an irregular plural form, that is, we do not add -s
or -es to make the plural forms of these words. Take a look at this
dialogue from the lesson.
What happened
to your forehead?
The power went out
last night while I was
brushing my teeth.
Now look at the plural forms of the words night and tooth.
SINGULAR
PLURAL
night
tooth
nights
teeth
Notice that we add -s to make the plural form of night. This is a regular
plural form. But the plural form of the word tooth is teeth. This is an
irregular plural form. You will learn about more words with irregular plural
forms in future lessons.
Here’s another example with the singular and plural forms of tooth.
Does that old dog
have any teeth?
104 — PEC 4 — L6 — TB
Well, he only has one
tooth left, but . . .
USING OFF, ONTO, AND OUT OF
Look at this dialogue from the lesson with the words off and onto.
Mom’s vase fell off
the shelf onto the
floor and broke.
Mom will be
really angry.
You learned that off, onto, and also out of indicate in what direction
a person or thing is moving. It’s sometimes difficult to understand the
difference between these words, but pictures can help. So let’s take a
look at these examples.
Judy’s falling off her bed.
The pencils are
rolling off the table
onto the floor.
Mike’s running out of his house.
140 — PEC 4 — L8 — TB
