Ran men's organisation, showing civility (7)
I believe the answer is:
manners
'civility' is the definition.
(thesaurus)
'ran men's organisation' is the wordplay.
'organisation' is an anagram indicator.
'ran'+'mens'='ranmens'
'ranmens' anagrammed gives 'MANNERS'.
'showing' acts as a link.
(Other definitions for manners that I've seen before include "Politeness" , "Social conduct" , "Etiquette" , "people at station, perhaps" , "Courtesy" .)
