Boozer with French name, writer hot in Asian city (5,4)
I believe the answer is:
phnom penh
'asian city' is the definition.
(capital of Cambodia)
'boozer with french name writer hot' is the wordplay.
'boozer with' becomes 'ph' (I can't explain this - if you can you should give a lot more credence to this answer).
'french name' becomes 'nom' ('name' in French).
'writer' becomes 'pen' (something which writes).
'hot' becomes 'h' (abbreviation eg on taps).
'ph'+'nom'+'pen'+'h'='PHNOM PENH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for phnom penh that I've seen before include "Cambodian capital" , "Capital of Cambodia" .)
