Gotten limp, organising somewhere to mix (7,3)
I believe the answer is:
melting pot
'somewhere to mix' is the definition.
I can't tell whether this definition defines the answer.
'gotten limp organising' is the wordplay.
'organising' is an anagram indicator.
'gotten'+'limp'='gottenlimp'
'gottenlimp' with letters rearranged gives 'MELTING-POT'.
Can you help me to learn more?
(Other definitions for melting pot that I've seen before include "Place where different peoples mix" , "multicultural area" , "In which to mix metals, immigrants" , "Vessel - place for mixture" , "Place where different peoples mingle" .)
