Can a speaker be thought-provoking?
Can a person be "thought-provoking"? Or is this term only properly applied to concepts and things such as articles, theories, concepts, questions?
The dictionary says thought-provoking means "causing people to think seriously about something." And, sure, people can certainly cause one to think seriously about something. But I think the term is meant to suggest a conceptual or intellectual element.
Solution 1:
thought-provoking adj. OED
prompting serious thought.
As in:
The speaker at tonight's event was very thought-provoking
and good use of the adjective.
