Here's a breakdown:
Absolute Adjectives/Adverbs:
* These words describe qualities that are either present or absent, with no degrees in between.
* They cannot be made comparative or superlative.
* Examples:
* Adjectives: perfect, unique, impossible, dead, pregnant, empty, full, round, square, etc.
* Adverbs: completely, totally, absolutely, entirely, etc.
Why are these words uncomparable?
* Perfect: Something is either perfect or it isn't. You can't have something that's "more perfect" or "less perfect."
* Unique: If something is unique, it is the only one of its kind. You can't have something that is "more unique" or "less unique."
* Dead: A person is either dead or alive. You can't be "more dead" or "less dead."
* Empty: A container is either empty or not. It can't be "more empty" or "less empty."
Important Note: While some absolute adjectives can be used in comparative or superlative forms, they might change their meaning. For instance, "more perfect" might imply a higher level of quality, but it wouldn't be the same as the original meaning of "perfect."
In summary:
Uncomparable adjectives and adverbs (or absolute adjectives and adverbs) are those that cannot be modified to express degrees of the quality they describe. They express a quality as either present or absent.
