guiltily

the word 'guiltily' is a modern english formation built upon the old english noun 'gylt', which denoted a wrongdoing or offense. the adjective 'guilty' emerged by adding the suffix '-y' (from old english '-ig'), meaning "characterized by", to this root, creating "characterized by guilt". the adverb was then systematically formed by appending the prolific old english adverbial suffix '-ly', which transforms adjectives into descriptors of manner. thus, the literal construction "in a manner characterized by guilt" perfectly captures the modern abstract meaning of performing an action while conscious of or revealing one's culpability.
