High class trams (5,3)
I believe the answer is:
smart set
'high' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'class trams' is the wordplay.
I cannot really understand how this works, but
'class' could be 'set' (I've seen this in other clues) and 'set' is found within the answer.
an anagram of 'trams' is 'smart' which is within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for smart set that I've seen before include "Mattress (anag) - "in" crowd" , "Trendy folk" , "Fashionable elite" .)
