To pile in disorder while showing respect (6)
I believe the answer is:
polite
'while showing respect' is the definition.
I can't tell whether this definition defines the answer.
'to pile in disorder' is the wordplay.
'in disorder' is an anagram indicator.
'to'+'pile'='topile'
'topile' anagrammed gives 'POLITE'.
Can you help me to learn more?
(Other definitions for polite that I've seen before include "Well-spoken and civil" , "Well mannered" , "Mannerly, courteous" , "Well-mannered, courteous" , "Good mannered and civil" .)
