Root Explanation

Exarch is derived from the Greek "exarchēs" (meaning leader or ruler), which itself comes from "exarkhein" (meaning to rule or to command). The term originally referred to a governor or a high-ranking official in the Byzantine Empire, particularly one who ruled over a province or a region.

Memory Tip

Think of a leader ('exarchēs') who is in charge of a specific area, which helps you remember that an exarch is a ruler or governor.
