Plaintive cries are heard in the principality (5)
I believe the answer is:
wales
'the principality' is the definition.
(Wales is an example)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for wales that I've seen before include "Part of 1" , "Home to Snowdonia and the Gower Peninsula" , "UK country" , "Principality, part of the UK" , "Home nation wearing red shirts for rugby" .)
