Try a couple over daughter that’s found concealed in trunk (9)
I believe the answer is:
heartwood
'found concealed in trunk' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe there's a link between them I don't understand?
'try a couple over daughter' is the wordplay.
'try' becomes 'hear' (as in to try someone in court or hear their case).
'a couple' becomes 'two' (two people or things).
'over' becomes 'o' (cricket abbreviation).
'daughter' becomes 'd' (genealogical abbreviation).
'hear'+'two'+'o'+'d'='HEARTWOOD'
'that's' is the link.
Can you help me to learn more?
(Another definition for heartwood that I've seen is " hard stuff".)
