Good sort (4)
I believe the answer is:
kind
This clue is a double definition.
'good' is the first definition.
(similar in meaning)
'sort' is the second definition.
(I know that sort can be written as kind)
(Other definitions for kind that I've seen before include "Sympathetic" , "Obliging" , "Sort of compassionate" , "Gracious" , "Type; good-hearted" .)
