Singular and Plural Nouns use
Singular is the form of a noun when we talk about one person, thing, or idea: a book, an apple.
Plural is the form we use when there are two or more: books, apples.
This topic helps you use the correct noun form, choose words like a/an, make plural forms, and match words such as this / that / these / those, it / they, and is / are.
Singular and Plural Nouns Form
Most countable nouns have a singular and a plural form. A singular countable noun usually cannot stand alone without a word before it: this is often a/an, but it can also be the, this, that, my, and similar words. The plural form is usually made with -s or -es, but some nouns have irregular plurals.
Singular: a pen, an apple, this book, that phone, my bag, it is ...
Plural: pens, apples, these books, those phones, my bags, they are ...
Singular and Plural Nouns Rule
-
A singular countable noun usually needs a word before it. This is often a/an, but it can also be the, this, that, my, and similar words. We usually use a before a consonant sound and an before a vowel sound.
✅ a pen✅ a river✅ an apple✅ an elephant✅ this book✅ my phone
-
To make a noun plural, we usually add -s.
✅ book → books✅ dog → dogs✅ phone → phones
-
If a noun ends in -ch, -sh, -s, -ss, -x, we usually add -es.
✅ watch → watches✅ dish → dishes✅ bus → buses✅ box → boxes
-
If a noun ends in consonant + y, y usually changes to ies. If there is a vowel before y, we usually just add -s.
✅ country → countries✅ baby → babies✅ boy → boys✅ day → days
-
Some nouns ending in -f or -fe make the plural with -ves.
✅ leaf → leaves✅ wife → wives✅ knife → knives

We use this / that with singular nouns and these / those with plural nouns. The verb must agree too: is with singular and are with plural.
✅ This is a pen.✅ That is a phone.✅ These are pens.✅ Those are phones.

Some nouns have an irregular plural form, so you need to learn them.
