Etymology and Origin of zeal definition
The word zeal comes from the Greek zelos, which meant ardor, jealousy, or rivalry, and moved into Latin and then Old French before arriving in English. That long journey explains why zeal carries both positive energy and an edge of rivalry or zealotry.
Over centuries authors used zeal to praise devotion, but also to warn when devotion became exclusionary or aggressive. Classic religious texts and modern speeches both use zeal, often with different connotations.
