Certain adjectives do not really admit of comparison because their meaning is already superlative; as,
Unique, Ideal, Perfect, Complete, Universal, Entire, Extreme, Chief, Square, Round
Do not therefore say:
Most Unique, quite unique, chiefest, extremest
But we still say, for instance:
This is the most perfect specimen I have seen.
Isn't the last example contradicting (by using most perfect) what they described above? What are they trying to imply here? What should I take away from it?
I have heard the expression 'quite unique' at-least in informal English. Is it incorrect in formal English?
I have seen the words 'squarer', 'squarest' and 'rounder', 'roundest' in the dictionary. So what's wrong with using them?
Suppose a child tries to draw a circle and it doesn't turn out to be a perfect circle, so they make another attempt and the circle they draw this time is better than the one they drew before; so you tell them that this one is rounder.
