The word 'urbanisation' charts the conceptual journey of making something city-like. Its core, 'urban', originates from the Latin urbs, meaning city, which itself may derive from a Proto-Indo-European root related to turning or plowing, hinting at the foundational act of settling land. The suffix '-ise' (via Latin and Greek) was attached to form the verb 'urbanise', meaning to make urban. Finally, the addition of the noun suffix '-ation' transforms the action into the name of the ongoing process. Thus, the literal "process of making into a city" perfectly captures the modern socio-economic phenomenon of population concentration and infrastructural development.
