Mean superintendent's part (6)
I believe the answer is:
intend
'mean' is the definition.
(to intend to something is to mean it)
'superintendent's part' is the wordplay.
'part' says the answer is hidden in the clue.
'INTEND' is hidden in the letters of 'superintendents'.
(Other definitions for intend that I've seen before include "Mean; aim" , "Aim, plan" , "Have as purpose or plan" , "1 dn [DESIGN]" , "Mean (to do something)" .)
