Cluster of flowers in spring, ten in Versailles (6)
I believe the answer is:
spadix
'versailles' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'cluster of flowers in spring ten' is the wordplay.
'cluster of flowers' becomes 'di' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'spring' becomes 'spa' (spa can mean a mineral spring).
'ten' becomes 'X' (Roman numeral).
'spa'+'x'='spax'
'di' inserted within 'spax' is 'SPADIX'.
'in' is the link.
Can you help me to learn more?
(Another definition for spadix that I've seen is " Spike of small flowers".)
