Fear of being wrongly partitioned (11)
I believe the answer is:
trepidation
'fear' is the definition.
(I know that trepidation is a type of apprehension)
'wrongly partitioned' is the wordplay.
'wrongly' indicates anagramming the letters (I've seen this in other clues).
'partitioned' anagrammed gives 'TREPIDATION'.
'of being' acts as a link.
(Other definitions for trepidation that I've seen before include "Fear or agitation about future events" , "Apprehension" , "Uneasy state" , "Feeling of anticipatory fear" , "Feeling of agitation and fear" .)
