Measure involved in all good summing-up (9)
I believe the answer is:
totalling
'summing-up' is the definition.
The definition and answer are not the same part of speech.
'measure involved in all good' is the wordplay.
'measure' becomes 'tot' (I have seen 'Measure of spirits' mean 'tot' so perhaps 'measure' could also mean 'tot').
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'good' becomes 'g' (abbreviation).
'in'+'all'='inall'
'inall' with letters rearranged gives 'allin'.
'tot'+'allin'+'g'='TOTALLING'
Can you help me to learn more?
(Other definitions for totalling that I've seen before include "Coming to" , "Summing to" , "Addition" .)
