Cardinal and Ordinal Adjectives Cardinal: these types of numbers answer the question, “how many?”
The first cardinal number is zero (0). Every time (0) is used, it requires a plural noun. Example: How many birds are in the backyard? There are zero birds. There are no birds. *remember*
Saying there are “no” birds is the same as saying there are “zero” birds. If you want to say there is one (1), this requires a singular noun.
Example: How many balls are on the court? There is one ball. One = Cardinal number adjective Ball = singular noun – representing one (1)
Every other number (2 > infinity) requires a plural noun.
How many guitars do you have? I have three guitars. Three = cardinal number adjective Guitars = plural noun representing three (3)
How many baseball cards do you have? I have 825 baseball cards. 825 = cardinal adjective Baseball cards = plural noun representing 825
