Etymology

Origin of monarch

First recorded in 1400–50; late Middle English, from Middle French monarche, monarch, from Late Latin monarcha, from Greek mónarchos “sole ruler, monarch”; see mon-, -arch

Explanation

If you think the Queen of England is just the coolest thing ever, then you like monarchs: hereditary rulers of countries usually known as king or queen. You might think your principal rules with absolute power, but that's not really true: there's a school board and an administration and she can't really control everything. But a monarch can. Monarch comes from the Greek mono, "one," and archon, "ruler." Many modern monarchies actually have parliaments and constitutions, leaving the monarch more symbolic than powerful. A monarch is also a particularly royal looking butterfly with orange wings and black and white spots.
