Taking great care of Diana and Elizabeth Ring? A man of some refinement! (10)
I believe the answer is:
diligently
'taking great care of diana and elizabeth ring? a man of some refinement' is the definition.
I can't tell whether this defines the answer.
'diana and elizabeth ring? a man of some refinement' is the wordplay.
I cannot quite see how this works, but
'diana' could be 'di' (Di is short for Diana) and 'di' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'man' could be 'ly' and 'ly' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for diligently that I've seen before include "with application" , "With meticulous care" .)
