Lesson 2: Singular and Plural Nouns (-s, -es)

Welcome back! When my English students talk about going to the market, they often forget to tell me if they bought one thing or many things.

Today, we are looking at how to turn a singular noun (one) into a plural noun (two or more) simply by adding -s or -es. Let's look at some things you see around town and learn the spelling rules to make them plural.

warning Common English Mistake
In many languages, we use numbers or quantity words but leave the noun exactly the same. In English, if you have more than one, you must change the noun itself. Always remember to add the '-s' or '-es' to the end of the word!

Lesson Summary & Review

Let's review the key concepts covered in the interactive module above to ensure you are ready to form English plurals correctly.

Plural Noun Spelling Rules

  • Add -s: For most regular English nouns, you just add an "s" to the end to make it plural (e.g., Tuk-Tuk becomes Tuk-Tuks, Market becomes Markets).
  • Add -es: If the singular noun ends in -s, -sh, -ch, -x, or -z, you must add "es" to make it plural (e.g., Bus becomes Buses, Box becomes Boxes, Watch becomes Watches).
  • Ends in -o: Many nouns ending in "o" also require adding "es" (e.g., Mango becomes Mangoes).

Why This Matters

If you have more than one item, you must always modify the noun. If you leave the noun singular when talking about plural objects, it will sound very confusing to a native English speaker.
