persuasively

the adverb 'persuasively' is built upon the core latin verb persuadere, meaning 'to convince thoroughly', which itself is a compound of per- (thoroughly) and suadere (to advise, urge). the adjective-forming suffix -ive was attached to create 'persuasive', describing something with the power to convince. finally, the old english adverbial suffix -ly, used to form adverbs from adjectives, was added, completing the word's grammatical journey to describe the manner of an action. thus, the word's literal construction leads to its modern meaning: 'in a manner that thoroughly urges or advises', i.e., in a convincing way.

Structure: persuas (convince) + ive (adjective suffix) + ly (adverb suffix) persuas (from latin persuadere, meaning 'to convince thoroughly'), ive (a suffix of latin origin forming adjectives meaning 'having the nature of'), ly (a native english suffix forming adverbs from adjectives)
