Land of song and wails, we're told (5)
I believe the answer is:
wales
'land of song' is the definition.
'Wales' can be an answer for 'land' (Wales is an example). I'm unsure of the 'of song' bit.
'wails we're told' is the wordplay.
'we're told' indicates a 'sounds like' (homophone) clue.
'wails' is a homophone of 'WALES'.
'and' is the link.
Can you help me to learn more?
(Other definitions for wales that I've seen before include "Cymru" , "International team" , "Home to Snowdonia and the Gower Peninsula" , "UK country" , "Part of Great Britain" .)
