imperialist

The word 'imperialist' is a modern formation built upon the much older term 'imperial'. Its core, 'imperial', traces back to the Latin imperium, signifying supreme authority, command, and dominion, which itself derives from the verb imperare (to command). The suffix '-ist', of Greek origin via Latin, is a productive agent-forming suffix used to denote an adherent of a practice or doctrine. Therefore, an 'imperialist' is literally 'one concerned with or practicing empire', a term that emerged in the 19th century to describe advocates and agents of policies aimed at acquiring and maintaining colonial empires, extending the abstract concept of imperium into a specific political ideology and practice.

Structure: imperial (relating to an empire) + ist (one who practices or believes in) - imperial: From Latin imperialis (of an empire or emperor), from imperium (command, supreme power, empire). Functions as the core adjective. - ist: From Greek -istēs, via Latin -ista, a suffix forming agent nouns denoting a person who practices or is concerned with something, or who adheres to a certain doctrine or system.
