Examples of plural words are different than the singular word?

You're absolutely right! Plural words often look very different from their singular counterparts. Here are some examples of how plural words can change:

1. Adding "-s" or "-es"

* Singular: cat, dog, book, chair

* Plural: cats, dogs, books, chairs

2. Changing the ending

* Singular: child, woman, man, mouse

* Plural: children, women, men, mice

3. Irregular forms

* Singular: sheep, deer, fish, goose

* Plural: sheep, deer, fish, geese

4. Latin and Greek words

* Singular: alumnus, bacterium, datum

* Plural: alumni, bacteria, data

5. Compound words

* Singular: toothbrush, stepchild

* Plural: toothbrushes, stepchildren

6. Words that don't change

* Singular: series, species, means

* Plural: series, species, means

7. Nouns that are always plural

* Singular: None

* Plural: pants, scissors, jeans

8. Nouns that are only used in the plural

* Singular: None

* Plural: goods, belongings, wages

These are just a few examples, but there are many more ways plural words can be formed. Understanding the different rules of pluralization is essential for correct grammar and writing.
