To pile untidily but in elegant style (6)
I believe the answer is:
polite
'to pile untidily but in elegant style' is the definition.
I can't tell whether this definition defines the answer.
'to pile untidily' is the wordplay.
'untidily' indicates an anagram (I've seen this in other clues).
'to'+'pile'='topile'
'topile' with letters rearranged gives 'POLITE'.
Can you help me to learn more?
(Other definitions for polite that I've seen before include "Well-behaved" , "Minding one's p's and q's" , "Not rude" , "Well-spoken and civil" , "Cultivated" .)
