Great ancient suburb of Dublin that attracted those with prospects in the past
I believe the answer is:
gold rush
'suburb of dublin that attracted those with prospects in the past' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'great ancient' is the wordplay.
I cannot really understand how this works, but
'ancient' could be 'old' ('old' can be similar in meaning to 'ancient') and 'old' is found within the answer.
'great' could be 'gr' and 'gr' is found within the leftover letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gold rush that I've seen before include "Prospective description" , "Klondike-style scramble?" , "Frenzied attempt to make money" , "Large migration of people to a new field of precious metal" , "Stampede of prospectors" .)
