University official made Anderson shelters (4)
I believe the answer is:
dean
'university official' is the definition.
(I've seen this before)
'made anderson shelters' is the wordplay.
'shelters' indicates a hidden word.
'DEAN' can be found hidden inside 'made anderson'.
(Other definitions for dean that I've seen before include "Senior church official" , "Head of e.g. faculty" , "Ice dancer" , "James ..., film actor" , "Cathedral official" .)
