What are some adjectives that higher level?

It's not clear what you mean by "higher level" adjectives. Could you give me more context?

Do you mean:

* Adjectives that describe a more advanced or complex level?

* For example, instead of "good," you might use "sophisticated" or "refined."

* Adjectives that have a more formal or academic tone?

* For example, instead of "big," you might use "immense" or "extensive."

* Adjectives that are simply longer or more unusual?

* For example, instead of "happy," you might use "euphoric" or "jocund."

Once you clarify what you're looking for, I can give you some specific examples.
