Crossword Genius

Section within department (4)

Ross

I believe the answer is:

part

'section' is the definition.
(I know that section can be written as part)

'within department' is the wordplay.
'within' indicates the answer is hidden within the clue.
'PART' can be found hidden inside 'department'.

(Other definitions for part that I've seen before include "Divide; role" , "Component; divide" , "Bit - leave" , "Member" , "goodbye" .)

I've seen this clue in The Mirror.
