Feed tablet to a rare form of butterfly? (11)
I believe the answer is:
caterpillar
'form of butterfly?' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'feed tablet to a rare' is the wordplay.
'feed' becomes 'cater' (I can't explain this - if you can you should give a lot more credence to this answer).
'tablet' becomes 'pill' (synonyms).
'rare' becomes 'r' (listed by Oxford Dictionary of Abbreviations).
'cater'+'pill'+'a'+'r'='CATERPILLAR'
Can you help me to learn more?
(Other definitions for caterpillar that I've seen before include "Track" , "potential beauty?" , "future monarch, perhaps" , "Butterfly/moth larva" , "Lepidopteran larva" .)
