Lesson Objectives

By the end of this lesson, you should be able to:

1. Define a compound noun.

2. Identify the singular and plural forms of compound nouns.

3. Use singular and plural compound nouns correctly in sentences.

Good day, class! Let’s play a quick game. I will say a noun and you will shout back the plural. Ready? One book… books! One pen… pens! Now, what if I say ‘one toothbrush’?

 toothbrushes? 

Aha! That’s what we’re learning today—compound nouns and how to use their singular and plural forms correctly!

• A compound noun is made up of two or more words that work together to name a person, place, thing, or idea.

• Examples: toothbrush, mother-in-law, classroom, passer-by

I say ‘tooth + brush’, you say
 Toothbrush!

Do you know there are types of compound nouns?

They are:

• Closed Form – The words are joined together.

  • Examples: toothbrush, classroom, sunflower

• Hyphenated Form – The words are joined with hyphens.

  • Examples: mother-in-law, commander-in-chief, passer-by

• Open Form – The words are written separately but function as one noun.

  • Examples: bus stop, high school, police station

1. Add ‘s’ to the main word:

   • toothbrush → toothbrushes

   • classroom → classrooms

     Change the important word inside:

     • mother-in-law → mothers-in-law

     • passer-by → passers-by

Kindly get the plural form of the following:

• Toothbrush

• Sister-in-law

• Schoolchild

• Housekeeper

• Man-of-war

1. Toothbrush

• Plural: Toothbrushes

• Sentences:

  • Singular: I forgot to pack my toothbrush for the trip.

2. Sister-in-law
