Some intervene — erasing superficial display (6)
I believe the answer is:
veneer
'display' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'some intervene erasing superficial' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'VENEER' can be found hidden inside 'intervene erasing superficial'.
Can you help me to learn more?
(Other definitions for veneer that I've seen before include "Finish" , "Prepared" , "Misleading external appearance" , "Thin coating on the outside" , "Superficial polish" .)
