Nouns and Articles: Noun Plurals and Possessives
Countable
nouns regularly add -s or -es to indicate the plural form. A plural noun
form is never followed by a verb with an -s ending.
Examples
Dogs bark.
The clerks in the corner store like telling jokes.
In Spanish and some other languages, adjectives have plural endings, just as nouns
do. However, in English adjectives never change form.
Example
I would advise the reader to try three different approaches.
