Discuss getting island a tree (7)
I believe the answer is:
conifer
'tree' is the definition.
(conifer is a kind of tree)
'discuss getting island a' is the wordplay.
I cannot quite understand how this works, but
'island' could be 'i' and 'i' is found within the answer.
'discuss' could be 'confer' (conferring is a kind of discussing) and 'confer' is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for conifer that I've seen before include "Eg, pine, fir or cypress" , "E.g. yew, pine or fir" , "Evergreen tree" , "Fir or larch, for example" , "Fir or pine, for example" .)
