Policeman finding sand, say, by large plant (6,5)
I believe the answer is:
copper beech
'large plant' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'policeman finding sand say' is the wordplay.
'policeman' becomes 'copper' (copper is a kind of policeman).
'finding' is a charade indicator (letters next to each other).
'sand' becomes 'beach' (sand can refer to a sandy beach).
'say' shows a homophone (sound like).
'beach' is a homophone of 'beech'.
'copper'+'beech'='COPPER BEECH'
'by' acts as a link.
Can you help me to learn more?
(Other definitions for copper beech that I've seen before include "Purplish-leaved tree" , "Never-green tree" , "Tree with purplish-brown leaves" , "Tree with dark-coloured leaves" , "Always autumn for this tree?" .)
