Courteous, considerate (5)
I believe the answer is:
civil
I believe this is a double definition.
'courteous' is the first definition.
(I've seen this in another clue)
'considerate' is the second definition.
(thesaurus)
(Other definitions for civil that I've seen before include "Polite to the state" , "Courteously polite" , "Nonviolent refusal to obey laws" , "Urbane" , "Courteous, polite" .)
