Poetic evocation to be green? (5)
I believe the answer is:
olive
'green?' is the definition.
(olive green is a kind of green)
'poetic evocation to be' is the wordplay.
'poetic evocation' becomes 'o' (I am not sure about this - if you are sure you should believe this answer much more).
'to be' becomes 'live' (to be is to live or exist).
'o'+'live'='OLIVE'
Can you help me to learn more?
(Other definitions for olive that I've seen before include "Fruit giving oil" , "woman" , "Oil-producing fruit" , "This branch is offered in peace gesture" , "Small green tree-fruit, nice in martini" .)
