Wealth? Put a limit on the lot abruptly! (7)
I believe the answer is:
capital
'wealth?' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for capital that I've seen before include "Fantastic!" , "Money available to produce interest" , "Excellent - assets - first city" , "Funds" , "source of profit" .)
