Citizen - city / urbis....

all connected, in some senses...

Citizen, from Latin civitatem, nominative civitas, in fact was a reference to a State, sometimes also to a city, and so to a city-State. The most curious is that the Sanskrit also is an Indo European language and then Siva divides with citizen the same root *kei-uo (IE) that in Pre-historical times meant "root".
Thus, city, citizen and, surprisingly, Siva, all recall their common origin on "root".
The word "home" has the same root!
So, when we speak about citizen we must also be attentive to the sense of "home", of our roots and, then, to the meaning of State.
Urbis - to mean the "sense" that a life has inside a city... very transformed in the megacities of the present - has an obscure origin. It starts to be used only with the Enlightment! Some authors suggest - however personally I don't believe very probable - that urbis would divide its roots with human - from the Indo European *ghomo - that meant "earth", and that also generated humus.
Beautiful, human and earth, humus, showing us the sense of humility - which is generated from the same root. - Emanuel
