Full of disgust or causing disgust; extremely repulsive or offensive.
From 'disgust' plus the adjectival suffix '-ful', meaning 'full of' or 'characterized by'. This suffix dates back to Old English and remains one of the most productive ways to form adjectives.
While 'disgusting' (present participle) is far more common, 'disgustful' emphasizes the quality of being full of disgust itself—a subtle distinction that shows English adjective formation offers multiple pathways to similar meanings.
