Design test on famous poem (5)
I believe the answer is:
motif
'design' is the definition.
(motif is a kind of design)
'test on famous poem' is the wordplay.
'test' becomes 'MOT' (as in an MOT test for a vehicle).
'on' says to put letters next to each other.
'famous poem' becomes 'if' (Rudyard Kipling poem. I am not sure about the 'famous' bit.).
'mot'+'if'='MOTIF'
Can you help me to learn more?
(Other definitions for motif that I've seen before include "Recurrent symbol" , "recurring idea" , "Dominant theme in art" , "Shape" , "Theme in music or book" .)
