Answer:
Absent, Cognate, Concise, etc.
Step-by-step explanation:
The adjectives that cannot be compared are the "non-comparable" adjectives which are defined as the qualities that can not be compared. To illustrate, the adjective "good" has comparable forms like 'better' and 'best', but if we take "Absolute" or "Abductive", they cannot be written as 'more absolute' or 'more abductive'. Thus, the adjectives that cannot be compared exemplify this category of adjectives and should not be used in the comparative or superlative degree.
