How to categorize 'perfect' and 'dead'? [duplicate]
Solution 1:
They are called ‘non-gradable adjectives’ (or ‘absolute adjectives’).
Non-gradable adjectives: absolute adjectives
Some adjectives are non-gradable. For example, something can't be a bit finished or very finished. You can't be a bit dead or very dead. These adjectives describe absolute qualities. To make them stronger we have to use modifiers like absolutely, totally or completely:
- Thank you, I love it! It's absolutely perfect!
- Their farm was totally destroyed by a tornado.
- My work is completely finished. Now I can relax.
