Fashionable girl providing a substitute for heroin makes 1000 guineas? (7)
I believe the answer is:
classic
'fashionable' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'girl providing a substitute for heroin makes 1000 guineas?' is the wordplay.
I cannot really understand how this works, but
'girl' could be 'las' (I've seen this in other clues) and 'las' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for classic that I've seen before include "Top-quality" , "Accepted as excellent" , "Remarkably typical" , "Epsom Derby or St Leger Stakes, for example" , "Eg, screw thread" .)
