Adjectives and Adverbs that Should Not Be Compared

"Absolute" adjectives and adverbs are ones that shouldn't be compared (by using words like more, less, best, worst, and so on) because of their meanings. One of the most frequently misused comparative adjectives is unique, meaning one of a kind. Something cannot be more unique or most unique. Something is either one of a kind or it isn't. Adjectives like this (and their adverbial forms) are absolute; in fact, the word absolute is an absolute adjective. Other words to watch out for are essential, meaning absolutely necessary; universal, meaning present everywhere; and immortal, meaning living forever. With these adjectives and adverbs, comparative degrees are meaningless.
