Is this the rank that managed the police department? (6)
I believe the answer is:
rancid
'is this the rank' is the definition.
'rancid' can be an answer for 'the rank' (thesaurus). I'm unsure of the rest of the definition.
'managed the police department?' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'the police department?' becomes 'cid' (I've seen this in other clues).
'ran'+'cid'='RANCID'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for rancid that I've seen before include "Smelling or tasting bad" , "Smelling or tasting of stale fat" , "(Of fatty foods) gone off" , "(Of fatty foods) stale" , "Sour like stale grease 96)" .)
