Special Pairs of Demonstrative Adjectives

The aforementioned adjectives are certainly not the only ones in the English language. Others include the pairs “the one” (sometimes just “one”) and “the other,” and “the former” and “the latter.” These words are used to refer to two things that have already been named in a sentence. Here are some examples of these special pairs of demonstrative adjectives in sentences.

How Can Numbers be Demonstrative Adjectives?

If you are wondering, what is a demonstrative adjective that looks like a number, you are probably thinking of ordinal numbers. Although these adjectives are used in our daily lives, we often do not think of them as demonstrative adjectives because they seem like numbers to us. These are the adjectives that follow from “first, second, third, fourth, fifth…” and increase over time. 

There are an infinite number of these adjectives. You can usually pick one that represents a number because, with a few exceptions, these are the ones that end in –th. These special adjectives are called ordinal numbers.

Let’s look at a few examples: the sentences showcase an ordinal number in action that is functioning like other demonstrative adjectives, and after the sentence, the ordinal number is indicated in parentheses. 

• The first paycheck I received was for $500.  (first)
• The seventh day of the week is Sunday. (seventh)
• In the late nineteenth century, the Civil War in the United States was fought. (nineteenth)
• After my third piece of pizza, I was stuffed. (third)
• For her fiftieth birthday party, we bought my mother a cake. (fiftieth)
