Top clue cunningly constructed? This one is word-wise! (7)
I believe the answer is:
octuple
'constructed? this one is word-wise' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'top clue cunningly' is the wordplay.
'cunningly' indicates anagramming the letters (a cunning or tricky form of the letters).
'top'+'clue'='topclue'
'topclue' with letters rearranged gives 'OCTUPLE'.
Can you help me to learn more?
(Other definitions for octuple that I've seen before include "8 times" , "multiply by eight" , "Couplet (anag)" , "Eightfold" , "more than seven times" .)
