Valuable song heard to take shape (8)
I believe the answer is:
heirloom
'valuable' is the definition.
The definition and answer can be both related to property as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'song heard to take shape' is the wordplay.
'song' becomes 'air' (I've seen this before).
'heard' indicates a 'sounds like' (homophone) clue.
'to take shape' becomes 'loom' (I've seen this in another clue).
'air' is a homophone of 'heir'.
'heir'+'loom'='HEIRLOOM'
Can you help me to learn more?
(Other definitions for heirloom that I've seen before include "Item handed down for years" , "Valuable family object" , "Valued possession that's handed down" , "something passed on" , "Valuable item still in family" .)
