Attitude underpinning Coronation Street's material? (9)
I believe the answer is:
soapstone
'attitude' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'underpinning coronation street's material?' is the wordplay.
'underpinning' means one lot of letters go next to another (in a down clue, some letters go under others).
'coronation street' becomes 'soap' (Coronation Street is a soap opera).
'material?' becomes 'stone' (stone is a kind of material).
'soap' put next to 'stone' is 'SOAPSTONE'.
Can you help me to learn more?
(Other definitions for soapstone that I've seen before include "Compact variety of talc - teaspoons (anag)" , "Soft talcy rock" , "Soft type of rock" , "Soft steatitic rock" , "Soft form of rock" .)
