A person or thing that edifies; something that instructs, improves, or uplifts someone morally or intellectually.
From edify plus the agent suffix -er (one who does the action). This is the standard formation for naming the person performing the action of edifying.
An edifier is what we might call an 'intellectual parent'—teachers, mentors, inspiring figures, even books can be edifiers because they all build up your character and knowledge in constructive ways.
