However, it can also be used as a noun to refer to something that is superficial, or as a verb meaning "to make or become superficial".
Here are some examples:
Adjective:
* "He made a superficial attempt to understand the problem."
* "Her knowledge of the subject was superficial."
Noun:
* "The book was full of superficiality." (referring to a lack of depth)
* "Their relationship was based on superficiality." (referring to a lack of substance)
Verb:
* "The company superficialized the product to appeal to a wider audience." (making it less deep)
* "His emotions began to superficialize over time." (becoming less genuine)
It's important to note that using "superficial" as a verb is less common than using it as an adjective or noun.
