Kind of question about personal skill? (7)

I believe the answer is:
amiable
'kind' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for amiable that I've seen before include "'Friendly, pleasant and good-tempered (7)'" , "'Affable, genial (7)'" , "Lovable, friendly" , "Charming" , "Friendly, kindly" .)
