Sense: adverb/1
'Influentially' is the broadest of these: it simply means having a notable effect on people or events, without specifying how. 'Powerfully' adds the idea of force or intensity — a powerfully delivered speech may overwhelm objections through sheer emotional weight. 'Authoritatively' draws on the speaker's recognised expertise or official position; a comment from the chief economist carries weight because of role, not just content. 'Persuasively' focuses on rational or emotional convincing — the arguer wins people over by reasoning or appeal, not by status or force. For example: the CEO spoke authoritatively because of her position, but the junior researcher argued so persuasively that everyone changed their minds. The same idea, written influentially in a newspaper, can eventually shift national policy.
Etymology
'Influentially' is formed from 'influential' (adjective) + the adverb suffix '-ly'. 'Influential' itself comes from 'influence' (from Latin 'influentia', meaning 'a flowing in'), which in medieval times referred to an astrological force believed to flow from the stars into human affairs and shape destiny. By the 1500s the word had lost its astrological sense and came to mean any power that affects how people think or act. The adjective 'influential' appeared in the 1600s, and the adverb 'influentially' followed in the 1700s.
