For example, are you looking for:
* A synonym for "academic" itself? Perhaps "scholarly," "intellectual," or "erudite."
* A word for something that is typically found in an academic setting? Like "lecture," "dissertation," or "syllabus."
* A word for someone who works in academia? "Professor," "researcher," or "faculty member."
Please provide more information about what you're trying to say, and I can give you a more accurate response.
