Adjectives are words we use to describe the noun. Simple words like "warm" and "fat" are adjectives commonly used in writing. One can make adverbs from some adjectives by adding the suffix ly. Example: take the adjective "beautiful," the adverb is beautifully. One can do it the other way around: take an adverb like "presumably," the adjective is "presumable". "Presumable innocence" means the accused is assumed to be innocent until proven guilty.
