Doctrine generally somewhat clumsily recalled (3)
I believe the answer is:
ism
'doctrine generally' is the definition.
(suffix for disciplines or schools of thought)
'somewhat clumsily recalled' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'recalled' says the letters should be written backwards (to recall can mean to bring something back).
'msi' is hidden in the letters of 'clumsily'.
'msi' written backwards gives 'ISM'.
(Other definitions for ism that I've seen before include "Any ideological doctrine" , "Informally, any doctrine or practice" , "Any doctrine or theory" , "Distinctive theory" , "Doctrine, philosophy" .)
