IPA: /ɪˈrʊdɪtli/
KK: /ɪˈrʊdɪtli/
In a way that shows great knowledge or learning.
She spoke eruditely about the history of art.
Eruditely is derived from "eruditus" (meaning educated or learned) in Latin, which comes from the root "e-" (meaning out) and "rudis" (meaning untrained or rough). The suffix "-ly" indicates the manner of doing something. Thus, eruditely means in a manner that is learned or educated, reflecting a high level of knowledge.
Think of someone who is 'learned' ('eruditus') and acts in a way that shows their education — that's what it means to do something eruditely.
