Learning about a hot Asian city (6)
I believe the answer is:
lahore
'asian city' is the definition.
(I've seen this before)
'learning about a hot' is the wordplay.
'learning' becomes 'lore' (both can mean tradition or knowledge).
'about' means one lot of letters goes inside another.
'hot' becomes 'h' (abbreviation eg on taps).
'a'+'h'='ah'
'lore' placed around 'ah' is 'LAHORE'.
(Other definitions for lahore that I've seen before include "Pak. Punjab city" , "Capital of Punjab" , "City in NE Pakistan" , "Or heal badly in Pakistan" , "Possible home for Pakistani" .)
