Kind of rum outraged Don (4-7)
I believe the answer is:
good-natured
'kind' is the definition.
('good-natured' is associated in meaning with 'kind')
'rum outraged don' is the subsidiary indication.
'rum' indicates an anagram.
'outraged'+'don'='outrageddon'
'outrageddon' with letters rearranged gives 'goodnatured'.
'of' is the link.
(Other definitions for good-natured that I've seen before include "Warm-hearted" , "Kind, friendly and patient" , "Kind, unselfish" .)
