Question

Which of these words is an example of an absolute adjective

Answer 1

A. Talented

B. Younger

C. Correct

D. Gentle

The answer is C. correct, you can not be more correct so therefore it is an absolute adjective.

Answer 2

Here is an example

You are either 'dead' or not; you can not be 'dead-er' or 'more dead' than someone.

Dead is therefore an example of an absolute adjective - adjectives that can not take a comparative or superlative ('dead-est') form.

Using an absolute adjective in a comparative sentences makes your English sound strange so watch out!

Another example of an absolute adjective is 'unique' because it means 'one of a kind' and, therefore, it can not be 'more unique' than something. It's either 'unique' or it isn't.
Hope this helps!
