Discriminating magistrate resolves to take tram (6)
I believe the answer is:
ageist
'tram' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ageist that I've seen before include "Discriminating on the basis of years lived" , "Discriminating against older people" , "One discriminating against those who may be getting on?" , "One who discriminates against on grounds of age" , "against vets" .)
