Question

Using your knowledge of roots, what diagnosis would you give to someone who fears books, lectures, and classes?

Answer 1

There's not a clear-cut answer to this one, but I can think of a few answers that may work:
bibliophobia: biblio = book, phobia = fear (this answer accounts for books, but not so much the other two)
logophobia: logos = words, phobia = fear (this answer works for all three things, but none of them specifically)
docophobia: doc = teach, phobia = fear (this may work best to account for all three, since they all have to do with teaching)

In any case, Wikipedia has a pretty extensive list of Greek and Latin roots, so you can try some others from here: http://en.wikipedia.org/wiki/List_of_Greek_and_Latin_roots_in_English

Answer 2

the answer is panophobia
