Question

What do we mean whenwe say plural form of noun​

Answer 1

One person, place or thing is a singular noun. Having more than one things, or having multiple people or places, that's referring to plural nouns.

For example,

• One school = singular
• Two schools = plural

We simply add s to the end of the noun for a lot of cases to make it a plural form. Though sometimes you'll have something like this

• One cross = singular
• Two crosses = plural

Note how we add on 'es' instead of simply 's'. This is so won't have a string of 's' letters at the end, and it adds on another syllable as well.

Some nouns are the same whether singular or plural. Such examples are

• fish
• deer
• sheep

So you could say something like "I caught one fish yesterday" or "The biologist estimates there are about 200 fish in the lake".
