How chintz is arranged (14)
I believe the answer is:
alphabetically
'how' is the definition.
Both the definition and answer are adverbs. Perhaps they are linked in a way I don't understand?
'chintz is arranged' is the wordplay.
I cannot quite understand how this works, but
'is' could be 'be' and 'be' is found in the answer.
This explanation may well be incorrect...
(Other definitions for alphabetically that I've seen before include "As ABCDE are arranged" , "As assigned by initial letters" .)
