Comparison of Adjectives -- Page 6
Adjectives not Compared There are a number of adjectives that should not be compared because the simple form of the adjective expresses the quality to the highest possible degree. For example, if the answer to a problem is correct, another answer could not be more correct. If a circle is absolutely round, another circle could not be more round. If a bottle is empty, another could not be more empty. Below are some of these adjectives that are not compared for the reasons given.
  1. perfect
  2. unique
  3. square
  4. universal
  5. single
  1. supreme
  2. fatal
  3. empty
  4. vertical
  5. full
  1. alone
  2. dead
  3. final
  4. mortal
  5. instantaneous
  1. deadly
  2. straight
  3. blind
  4. everlasting
  5. wrong
  1. incorrect
  2. infinite
  3. top
  4. bottom
  5. right
  1. left
  2. center
  3. middle
  4. correct
  5. end

The expression, more nearly round, is often used when comparing two things, one of which is more nearly round than the other. In this case, however, neither of the things being compared is round. A line could be more nearly straight than another line if neither line was absolutely straight.

Sometimes an adjective such as the word honest is used in the comparative and superlative degrees. In such cases, we have no standard of absolute honesty. What the writer or speaker means is that one person approaches the absolute state of honesty to a greater or a lesser degree than another person. The adjective perfect is often used in the same way.
