Measure of liquid found in dive's nerve centre? (12)
I believe the answer is:
headquarters
'nerve centre?' is the definition.
(nerve centre can mean a control centre or HQ)
'measure of liquid found in dive's' is the wordplay.
'measure of liquid' becomes 'quart' (I can't explain this - if you can you should give a lot more credence to this answer).
'found in' indicates putting letters inside.
'dive's' becomes 'header's' (a header is a dive forwards).
'quart' placed inside 'headers' is 'HEADQUARTERS'.
Can you help me to learn more?
(Other definitions for headquarters that I've seen before include "Centre of operations" , "Base" , "Operational centre" , "Command centre" , "Military command post" .)
