Retreat from one who pulls big teeth? (5,5)
I believe the answer is:
ivory tower
'retreat' is the definition.
(I've seen this in another clue)
'from one who pulls big teeth?' is the wordplay.
I cannot really understand how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
'one' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ivory tower that I've seen before include "State of seclusion from worldly realities" , "academic position" , "Academia (seen as secluded)" , "Seclusion from ordinary life" .)
