Etymology

Origin of bridle

before 900; Middle English bridel, Old English brīdel for brigdels, equivalent to brigd- (variant stem of bregdan to braid ( def. ) ) + -els noun suffix; akin to Dutch breidel, Old High German brittel

Explanation

When you're riding a horse and scream "Whoa!" to make it stop, you're pulling on the reins, which are attached to a thing called the bridle, the buckled straps around a horse's head that help you control its movements. The word bridle comes from the Old English bridel meaning "rein, curb, restraint," which is precisely what the purpose of a bridle is — to help restrain a horse's movements when necessary. You can bridle a horse, which is the act of putting a bridle on it. If you yank too hard on the reins, your horse might bridle, or take offense to your aggressiveness, just like you might bridle if someone insulted you.
