sociologist

The word 'sociologist' is a modern compound built from classical elements. Its core, 'soci-', originates from the Latin socius, meaning companion or ally, which itself derives from the Proto-Indo-European root sekw- (to follow). The suffix '-ology', from Greek -logia (discourse, study), was appended to create 'sociology', the scientific study of companionship and human association. Finally, the agent suffix '-ist', of Greek origin via Latin, was added to designate a practitioner of this science. Thus, a sociologist is literally one who studies the principles of human companionship and societal organization.
