See a lowly junk in arm of Pacific (6,3)
I believe the answer is:
yellow sea
'arm of pacific' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'see a lowly junk' is the wordplay.
'junk' indicates an anagram.
'see'+'a'+'lowly'='seealowly'
'seealowly' anagrammed gives 'YELLOW SEA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for yellow sea that I've seen before include "Part of Pacific between Korea and China" , "Waters around China" , "main area" , "Ocean to W of Korean peninsula" , "Eastern ocean" .)
