Gallants to rematerialize after much delay (2,4,4)
I believe the answer is:
at long last
'after much delay' is the definition.
(I've seen this before)
'gallants to rematerialize' is the wordplay.
'gallants to' can be anagrammed to 'AT LONG LAST'.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for at long last that I've seen before include "Where cobbler dealing with size 12 shoes will be" , "cobbling size seventeens?" , "repairing the biggest shoes?" , "Finally" , "After much delay" .)
