An object or word has a plural form when it can be used to talk about more than one thing. For example, "cat" becomes "cats".
When we need to talk about multiple things, we often use the plural form of words. For instance, if you have many dogs and they all love playing fetch, you might say, "My dogs are very energetic." The word "dog" is in its singular form, but when it's used with a number or more than one thing, it becomes "dogs", which is its plural form.
Consisting of or containing more than one of something.
Example: The notion of culture is one whose meanings are plural and shifting.
