Can a noun be plural

Answer 1

Yes, most nouns have a singular and a plural form. A plural noun is a word for two or more people, places, or things (one apple or two apples; one egg or a dozen eggs; one child or two children).

There are some nouns that are called uncountable (or mass nouns). An uncountable noun is noun for something that is indivisible into countable units. Uncountable nouns typically identify something abstract or something that is tangible but not identified as separate objects; for example:

abstract concepts: courage, education, humor, humility, warnth, wealth

activities and sports: football, hockey, knitting, shopping, fishing, polo

academic subjects: Biology, folklore, linguistics, history, physics, math

food and drink (some): bread, flour, corn, fish, rice, ginger, water, tea

other substances/materials: air, oil, cement, cotton, powder, soil, hydrogen

aggregates: furniture, equipment, news, communications, police, goods

binary nouns: pants, pajamas, shorts, tweezers, scissors, binoculars

Non-count nouns are expressed as amounts or measures:

cups of rice, pounds of rice

teaspoons of sugar, pounds of sugar

tins of tea, glasses of tea

pieces of furniture, suites of furniture

tons of aluminum, rolls of aluminum

volts of electricity, currents of electricity

some information, pieces of information

bits of news, a lot of news

a little advice, pieces of advice

little knowledge, a great deal of knowledge

Answer 2

Yes, nouns can be plural. Plural nouns refer to more than one person, place, thing, or idea. They are usually formed by adding "-s" or "-es" to the singular form of the noun.
