Did you know?
In Homer's Iliad, Hector, the eldest son of King Priam of Troy, was a model soldier, son, father, and friend, the champion of the Trojan army until he was killed by the Greek hero Achilles. How did the name of a Trojan paragon become a verb meaning to bully or harrass? That use was likely influenced by gangs of rowdy street toughs who roamed London in the 17th century and called themselves Hectors. They may have thought themselves gallant young blades, but to the general populace they were swaggering bullies who intimidated passersby and vandalized property. By 1660, hector was being used both as a verb and as a noun meaning bully.
