Ill-disposed to put files in order (8)
I believe the answer is:
spiteful
'in order' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'ill-disposed to put files' is the wordplay.
'ill disposed' is an anagram indicator.
'put'+'files'='putfiles'
'putfiles' is an anagram of 'SPITEFUL'.
Can you help me to learn more?
(Other definitions for spiteful that I've seen before include "nasty!" , "With desire to hurt" , "Malevolent, wanting to hurt" , "Vengeful, malicious" , "Showing malice" .)
