'shopping centre's' is the definition.
Both the answer and definition are singular nouns.

'withdrawn' is a reversal indicator.
'tram' written backwards gives 'MART'.

Can you help me to learn more?

(Other definitions for mart that I've seen before include "Trading centre" , "Place" , "Take tram to market" , "US shop; market" .)

I've seen this clue in The Telegraph.
