Learning about a hot city in Pakistan (6)
I believe the answer is:
lahore
'city in pakistan' is the definition.
(I've seen this before)
'learning about a hot' is the wordplay.
'learning' becomes 'lore' (I've seen this before).
'about' means one lot of letters goes inside another.
'hot' becomes 'h'.
'a'+'h'='ah'
'lore' enclosing 'ah' is 'LAHORE'.
(Other definitions for lahore that I've seen before include "Asian city" , "Possible home for Pakistani" , "West Pakistan capital, 1955-70" , "Pakistan's second city" , "Oh, real city of Pakistan" .)
