the word 'successfully' is built upon the latin noun 'successus', which itself derives from the verb 'succedere', meaning "to come after, go under, follow after, fare well." this verb is a compound of 'sub-' (under, close to) and 'cedere' (to go, yield). the original sense of "a following after" evolved in latin to denote a favorable outcome or prosperity. the english word 'success' adopted this positive meaning. the addition of the old english adjectival suffix '-ful' created 'successful', meaning "full of or characterized by success." finally, the old english adverbial suffix '-ly' was appended to form 'successfully', specifying the manner of an action performed with a successful outcome. thus, the term encapsulates a journey from a literal notion of sequence to an abstract concept of favorable achievement, grammatically shaped by germanic suffixes.

Structure: success (result) + ful (adjective suffix) + ly (adverb suffix) - success: from latin 'successus' (an advance, a good result, outcome), functioning as the core noun root. - ful: from old english '-ful', a suffix meaning "full of", functioning to convert the noun into an adjective ('successful'). - ly: from old english '-līc', a suffix forming adverbs from adjectives, indicating manner.
