What are Countable Nouns?
Countable nouns are for things we can count. We can use numbers with them.
- They have a singular form (one thing) and a plural form (more than one thing).
- Examples: a book, two books; one car, three cars.
- We can use a または an with singular countable nouns.
What are Uncountable Nouns?
Uncountable nouns are for things we cannot count individually. They often represent ideas, substances, or collections.
- They usually have only one form (singular).
- Examples: water, sugar, information, advice.
- We cannot use a または an with uncountable nouns.
- To talk about quantity, we use words like some, much, or phrases like a glass of water.
How Do We Make Plural Nouns?
Most countable nouns become plural by following simple rules. Here are the main ways:
- Add -s: This is the most common rule.
例： cat → cats, book → books. - Add -es for nouns ending in -s, -ss, -sh, -ch, -x, -z:
例： bus → buses, watch → watches, box → boxes. - Add -es for nouns ending in -o after a consonant:
例： tomato → tomatoes, potato → potatoes. (But note exceptions like photo → photos). - Change -y ～へ -ies for nouns ending in -y after a consonant:
例： baby → babies, story → stories. - Add -s for nouns ending in -y after a vowel:
例： toy → toys, key → keys.
Are There Any Irregular Plural Nouns?
