Scared, court heard, in the main (6,3)
I believe the answer is:
yellow sea
'main' is the definition.
(Yellow Sea is an example)
'scared court heard' is the wordplay.
'scared' becomes 'yellow' (I can't justify this - if you can you should believe this answer much more).
'court' becomes 'see' (both can mean to date somebody).
'heard' shows a homophone (sound like).
'see' is a homophone of 'sea'.
'yellow'+'sea'='YELLOW SEA'
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for yellow sea that I've seen before include "main area" , "water from the east" , "Ocean to W of Korean peninsula" , "Eastern ocean" , "Part of Pacific between Korea and China" .)
