dreadful

the word dreadful is a native english formation, built from the old english verb drǣdan, meaning "to fear". this verb is of germanic origin, likely related to old high german trātan meaning "to fear". the suffix -ful, also from old english, is used to create adjectives indicating an abundance of the quality denoted by the root. thus, the literal construction "full of dread" perfectly captures the modern senses of the word. it first described something inspiring profound fear or terror, and over time, its meaning broadened through hyperbole to also describe anything extremely bad or unpleasant, intensifying the root sense of dread into a more general term of strong disapproval or awfulness.
