Kind - behaviour (6)
I believe the answer is:
manner
I believe this is a double definition.
'kind' is the first definition.
(I know that manner is a type of kind)
'behaviour' is the second definition.
(I know that manner is a type of behaviour)
(Other definitions for manner that I've seen before include "Way of acting or behaving" , "Way or means" , "How something is said or done" , "Bearing - fashion" , "Way in which something is done" .)
