   • If there is no noun in the compound, add -s to the end:

     • breakdown → breakdowns
     • check-in → check-ins
     • grown-up → grown-ups

Uncountable Nouns

Some nouns in English are uncountable, meaning they don't have a plural form. These nouns are always treated as singular.

Common Uncountable Nouns

1. Liquids and substances

   • water, milk, coffee, tea, oil, gas
   • air, smoke, pollution

2. Food items

   • bread, butter, cheese, meat, rice, sugar

   • advice, information, knowledge, news
   • education, homework, work, research
   • fun, happiness, health, love, music

4. Activities and sports

   • soccer, tennis, swimming
   • shopping, traveling

Using Uncountable Nouns

To express quantity with uncountable nouns, use expressions like:

• a piece of advice, two pieces of information
• a bottle of water, three cups of coffee
• a loaf of bread, two slices of cheese
• a bit of fun, a lot of happiness

Plural vs. Singular for Specific Cases

1. Collective nouns can be singular or plural depending on whether the group acts as a unit or as individuals:

   • The team is winning the championship. (acting as a unit)
   • The team are wearing their new uniforms. (acting as individuals)

2. Titles of works are usually singular even if they look plural:

   • "Great Expectations" is a novel by Charles Dickens.
   • "The Simpsons" is my favorite TV show.

3. Some nouns ending in -s appear plural but take singular verbs:

   • Mathematics is my favorite subject.
   • The news is on at 6 PM.
   • Physics involves the study of matter and energy.

Examples in Context

• There are five books on the table.
• Two children are playing in the park.
• I need to buy new shoes.
• My teeth are very sensitive to cold.
• The women in my family are all teachers.
• The information you gave me was very helpful. (uncountable)
