Hell has always encompassed the Forbidden City (5)
I believe the answer is:
lhasa
'forbidden city' is the definition.
(I've seen this in another clue)
'hell has always encompassed' is the wordplay.
'LHASA' is hidden within the letters.
But, I'm unsure how this is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for lhasa that I've seen before include "Tibet's "Forbidden City"" , "Capital of Tibet" , "foreign capital" , "The Forbidden City in Tibet" , "Sacred city" .)
