Level:Beginner to Elementary
Topic:Regular and irregular plural nouns

1. Greeting and Warm-up (1 minute)

Teacher:
Good morning, everyone. Today we are going to learn aboutregular nounsandirregular nouns.

Actually, to be more precise, we are going to talk aboutregular plural nounsandirregular plural nouns.
Anoun/naʊn/ names a person, place, thing, animal, or idea.
Most nouns can become plural. How they change tells us if they are regular or irregular.

Look at these two examples:

• one book → twobooks
• one child → twochildren

In the first example, we simply add-s. That is aregular noun.
In the second example, the word changes completely. That is anirregular noun.

Today we will learn the rules for both.

2. Regular Plural Nouns (2 minutes)

Teacher:
Let’s start withregular nouns.
A regular noun forms its plural in a predictable way.

(Write on the board.)

Regular plural rules:

1. Add-sto most nouns.
   book → books
   car → cars
   dog → dogs

2. Add-esafters, x, ch, sh, o.
   bus → buses
   box → boxes
   watch → watches
   dish → dishes
   potato → potatoes

3. Consonant +y→ changeytoiand add-es.
   city → cities
   baby → babies
   study → studies(noun: study → studies)

4. Vowel +y→ just add-s.
   boy → boys
   day → days
   toy → toys

5. Some nouns ending inf / fe→ change to-ves.
   knife → knives
   wife → wives
   leaf → leaves
   wolf → wolves

But be careful: some just add-s.
roof → roofs
chief → chiefs
belief → beliefs

Teacher:
So regular nouns follow clear rules. You can usually predict the plural form.

Repeat after me:
book → books
box → boxes
city → cities
knife → knives

(Students repeat.)

3. Irregular Plural Nouns (2.5 minutes)

Teacher:
Now let’s look atirregular nouns.

(Write on the board.)

Common irregular plurals:

• man →men

Some nouns come from Latin or Greek:

Repeat after me:
man → men

(Students repeat.)

4. Uncountable Nouns (1 minute)

They do not have a plural form.
