Angler brewed tea to be guzzled in Russian port (9)
I believe the answer is:
archangel
'russian port' is the definition.
(city and port in Archangelsk oblast, Russia)
'angler brewed tea to be guzzled' is the wordplay.
I cannot really see how this works, but
'tea' could be 'cha' (cha is a type of tea) and 'cha' is found in the answer.
an anagram of 'angler' is 'arngel' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for archangel that I've seen before include "The head celestial messenger" , "What we call a port" , "Russian city" , "Gabriel, for example" , "Nag Rachel (anag.)" .)
