Press for some candour generally (4)
I believe the answer is:
urge
'press for' is the definition.
(I've seen this in another clue)
'some candour generally' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'URGE' is hidden within 'candour generally'.
(Other definitions for urge that I've seen before include "Constrain" , "Strong impulse, desire" , "Impel, egg on" , "Encourage; impulse" , "'Exhort, press (4)'" .)
