What are examples of uncountable nouns?

1 Answer

An uncountable noun is noun for something that is indivisible into countable units; a word that normally has only a singular or a plural form.
An uncountable noun may be referred to as a non-count noun or a mass noun.


Examples of uncountable nouns are:
abstract concepts: courage, honesty, knowledge, scorn, homework, cooperation
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
miscellaneous: luggage, barracks, measles, weather, electricity

Note: Many uncountable nouns for substances do have a plural form (teas, oils, etc.). The plural form of these nouns are specifically used for "types of" or "kinds of" the substance, for example:
-a variety of teas
-a combination of oils

Another note: The uncountable noun "fish" is a word for the food substance. The plural noun "fishes' is a word for two or more creatures. The singular and the plural form can be used for two or more of these creatures:
-There are four fish in the tank.
-There are four fishes in the tank.
