Copper-coloured - like kippers? (5)
I believe the answer is:
cured
'copper-coloured like kippers?' is the definition.
I can't judge whether this defines the answer.
'copper-coloured' is the wordplay.
'copper' becomes 'Cu' (Cu is the chemical symbol for copper).
'coloured' becomes 'red' (similar in meaning).
'cu'+'red'='CURED'
Can you help me to learn more?
(Other definitions for cured that I've seen before include "Freed of disease" , "Mended" , "Healed - smoked" , "Healed - preserved" , "Made better or preserved" .)
