== Etymology ==
The word ''city'' and the related ''[[civilization]]'' come from the [[Latin]] root ''[[wikt:civitas|civitas]]'', originally meaning 'citizenship' or 'community member' and eventually coming to correspond with ''[[wikt:urbs|urbs]]'', meaning 'city' in a more physical sense.<ref name="OED">"city, n.", ''Oxford English Dictionary'', June 2014.</ref> The Roman ''civitas'' was closely linked with the Greek ''[[polis]]''—another common root appearing in English words such as ''[[metropolis]]''.<ref>Yi Jianping, "'Civilization' and 'State': An Etymological Perspective"; ''Social Sciences in China'' 33(2), 2012; {{doi|10.1080/02529203.2012.677292}}.

In [[toponymic]] terminology, names of individual cities and towns are called ''astionyms'' (from [[Ancient Greek]] ἄστυ 'city or town' and ὄνομα 'name').{{sfn|Room|1996|p=13}}
