Civility, politeness (8)
I believe the answer is:
courtesy
I believe this is a double definition.
'civility' is the first definition.
(I know that courtesy is a type of civility)
'politeness' is the second definition.
(I know that courtesy is a type of politeness)
(Other definitions for courtesy that I've seen before include "Politeness and respect for others" , "Civility, politeness" , "Good manners" , "Respectful and considerate behaviour" , "good breeding" .)
