Hour in depression for analyst (6)
I believe the answer is:
shrink
'for analyst' is the definition.
(I've seen this in another clue)
'hour in depression' is the wordplay.
'hour' becomes 'hr' (abbreviation).
'in' indicates putting letters inside.
'depression' becomes 'sink' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hr' inserted within 'sink' is 'SHRINK'.
Can you help me to learn more?
(Other definitions for shrink that I've seen before include "Get smaller - psychiatrist" , "Reduce in size" , "Recoil from a slangy psychiatrist" , "Shrivel" , "Contract, reduce" .)
