Loud officers reaching sticky end (6)
I believe the answer is:
brassy
'loud' is the definition.
(brassy can mean loud like brass instruments)
'officers reaching sticky end' is the wordplay.
'officers' becomes 'brass' (I've seen this in another clue).
'reaching' is a charade indicator (letters next to each other).
'sticky end' becomes 'y' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'brass'+'y'='BRASSY'
Can you help me to learn more?
(Other definitions for brassy that I've seen before include "Gaudy" , "Brazen-faced - harsh" , "Audacious" , "Tastelessly showy, loud" , "Tasteless and loud" .)
