Pub in Brussels charges for Iraqi's water (9)
I believe the answer is:
euphrates
'iraqi's water' is the definition.
'Euphrates' can be an answer for 'water' (Euphrates is an example). I'm not sure about the 'iraqi's' bit.
'pub in brussels charges' is the wordplay.
'pub' becomes 'ph' (public house).
'in' indicates putting letters inside.
'brussels' becomes 'EU' (European Parliament is based in Brussels).
'charges' becomes 'rates' (rate is a kind of charge).
'eu'+'rates'='eurates'
'ph' inserted into 'eurates' is 'EUPHRATES'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for euphrates that I've seen before include "River flowing through Turkey, Syria and Iraq" , "River which joins Tigris in Iraq" , "running water in SW Asia" , "River of Babylon" , "Asian river" .)
