Communist character, say, from body of water (3,3)
I believe the answer is:
red sea
'body of water' is the definition.
(Red Sea is an example)
'communist character say' is the wordplay.
'communist' becomes 'red' (red is a kind of communist).
'character' becomes 'c'.
'say' indicates a 'sounds like' (homophone) clue.
'c' is a homophone of 'sea'.
'red'+'sea'='RED SEA'
'from' is the link.
(Other definitions for red sea that I've seen before include "It divides Arabia/Africa" , "Water bordering Egypt" , "What the Suez canal links with the Mediterranean" , "Long narrow stretch of water between Africa and Arabia" , "Colourful body of water between N Africa and Arabian peninsula" .)
