Absolute adjectives describe a quality that cannot be compared or intensified. They represent a state or condition that is either present or absent, with no degrees in between. Some common examples of absolute adjectives include:
unique
perfect
complete
dead
pregnant
Since these adjectives indicate an absolute state, they should not be used with comparative or superlative forms.
To sum up, adjectives in English can take different forms, such as comparative, superlative, and absolute adjectives. Understanding the differences among these types and their formation rules can help improve clarity and precision in written and spoken communication.
