illicitly

the word 'illicitly' is built upon the latin adjective 'licitus,' meaning "lawful" or "permitted," which itself derives from the verb 'licēre,' "to be allowed." the negative prefix 'in-' (meaning "not") was assimilated to 'il-' before the root beginning with 'l,' creating 'illicitus'—literally "not lawful." this latin term passed into english as 'illicit,' an adjective describing something forbidden. the modern adverb 'illicitly' was formed by appending the native english adverbial suffix '-ly,' which denotes manner, to complete the word's journey from a literal latin negation of legality to its current abstract sense describing an action performed in an unauthorized way.

Structure: il (not) + licit (lawful) + ly (adverb suffix) il: latin origin, a prefix meaning "not" or "without," an assimilated form of 'in-' before 'l'. licit: latin origin, from 'licitus' meaning "lawful," functioning as the core adjective root. ly: old english origin, a suffix forming adverbs from adjectives, indicating manner.
