Learning dancing routine with Di (9)
I believe the answer is:
erudition
'learning' is the definition.
(I know that learning can be written as erudition)
'dancing routine with di' is the wordplay.
'dancing' indicates anagramming the letters.
'with' means one lot of letters goes inside another.
'routine' is an anagram of 'erution'.
'erution' enclosing 'di' is 'ERUDITION'.
(Other definitions for erudition that I've seen before include "profound scholarly knowledge" , "Great learning" , "Knowledge, learning" , "Learnedness, scholarship" , "being widely read" .)
