Hold discussion about one’s evergreen? (7)
I believe the answer is:
conifer
'evergreen?' is the definition.
(I've seen this in another clue)
'hold discussion about one's' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for conifer that I've seen before include "Evergreen (generally)" , "one branching out" , "Evergreen tree" , "In force (anag.)" , "Fir or pine, for example" .)
