Ponder convoluted tube that's finally manufactured (3,7)
I believe the answer is:
end product
'that's finally manufactured' is the definition.
I can't judge whether this definition defines the answer.
'ponder convoluted tube' is the wordplay.
'convoluted' is an anagram indicator.
'tube' becomes 'duct' (I've seen this before).
'ponder' with letters rearranged gives 'endpro'.
'endpro'+'duct'='END-PRODUCT'
Can you help me to learn more?
(Other definitions for end product that I've seen before include "Final result" , "finished article" , "processor's output" , "outcome" , "Finished item" .)
