Scottish candle centre (4)
I believe the answer is:
wick
This clue could be a double definition.
'scottish candle' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'centre' is the second definition.
(I have seen 'Centre of candle ' mean 'wick' so perhaps 'centre' could also mean 'wick')
Can you help me to learn more?
(Other definitions for wick that I've seen before include "Cord conveying liquid by capillary action" , "Northern town" , "Candle's thread" , "Candle fibre" , "See 1" .)
