Copper lining for one doctor’s piece of kitchenware (6)
I believe the answer is:
eggcup
'piece of kitchenware' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'copper lining for one doctor's' is the wordplay.
'copper' becomes 'cu' (Cu is the chemical symbol for copper).
'lining' means one lot of letters goes inside another.
'for one' becomes 'eg' (both can mean 'for example').
'doctor' becomes 'GP' (general practitioner).
'eg'+'gp'='eggp'
'cu' placed into 'eggp' is 'EGGCUP'.
Can you help me to learn more?
(Other definitions for eggcup that I've seen before include "Holder of an oval thing" , "what held a problem for curate?" , "Breakfast placed here" , "Bearer of breakfast (with soldiers)" .)
