the word 'unlawfully' is a layered construction built upon the old english noun 'law'. the negative prefix 'un-', also of old english origin, was attached to the adjective 'lawful' to create its opposite, 'unlawful', meaning "not conforming to the law". finally, the old english adverbial suffix '-fully' (a combination of '-ful' and '-ly') was added to form the adverb, describing an action performed in an illegal manner. this word exemplifies the analytic capacity of english to create precise legal terminology through the sequential combination of native germanic elements.
