An elevating Kipling poem of unaffected simplicity (4)
I believe the answer is:
naif
'unaffected simplicity' is the definition.
(I've seen this before)
'an elevating kipling poem' is the wordplay.
'an elevating' becomes 'na' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'kipling poem' becomes 'If' (poem by Rudyard Kipling).
'na'+'if'='NAIF'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for naif that I've seen before include "Inexperienced" , "unaffected simplicity" , "Unsophisticated" , "somewhat ingenuous" , "Green" .)
