Adjectives are words that describe the qualities of something. Some adjectives in English are gradable - that means you can have different degrees or levels of that quality. For example, the weather can be a little cold, rather cold, very cold, or extremely cold.
Extreme adjectives or non-gradable adjectives are words that mean “extremely + adjective” – for example, “freezing” means “extremely cold.” The weather can’t be “a little bit freezing” or “very freezing” – because the word “freezing” itself automatically means “extremely cold.”
