Deliveries with wrong, wrong, wrong quantity of Flora (9)
I believe the answer is:
overgrown
'wrong quantity of flora' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'deliveries with wrong wrong' is the wordplay.
'deliveries' becomes 'over' (I've seen this before).
'with' says to put letters next to each other.
'wrong' indicates an anagram.
'wrong' with letters rearranged gives 'grown'.
'over'+'grown'='OVERGROWN'
Can you help me to learn more?
(Other definitions for overgrown that I've seen before include "Wild" , "in oversize state" , "Covered by vegetation" , "covered with weeds" .)
