Why English Puts a Hat on Everything

 

Our heads serve many purposes. They hold our brains, cover our hairline losses, and give eyeglasses somewhere to sit. But one of their most important functions is as a hat rack, which may explain why so many of our idioms involve headgear. Apparently, English looked at the human head and thought, “Yes, but what if we put a metaphor on it?”

I had an Aunt Joyce who my dad always declared was “mad as a hatter.” When you’re seven years old, that’s funny as heck, mostly because you picture a woman in a giant hat chasing the mailman down the street with a cane, cursing him for bringing more junk mail. It made absolutely no sense, of course, but at that age, neither did taxes, liver, or why adults thought prunes were food. For decades, I never bothered to investigate, but the saying has an interesting origin.

“Mad as a hatter” means extremely eccentric, irrational, or “crazy,” and its origin is tied to 19th-century hat making. Hatters commonly used mercury nitrate in the process of turning animal fur into felt for hats. Long-term mercury exposure led to tremors, mood changes, irritability, memory problems, and erratic behavior. Many hat makers became mentally unstable due to the exposure to mercury, and the phrase stuck.

So imagine my dad said to me, “Your Aunt Joyce is nuts, but keep it under your hat.” That’s an adult way of saying “Don’t tell anyone.” It likely comes from the idea that a hat was a private, personal place to hide or cover something. In older times, a person might tuck small items, notes, or money inside a hat lining. So if something was “under your hat,” it was hidden from view and kept to yourself. Your secret is safe with me, Aunt Joyce.

But while Dad and I were laughing at Aunt Joyce's bizarre antics, my mom comes in and starts yelling at us for ridiculing her sister. I ask my dad what’s wrong, and he says, “Oh, your mother goes off at the drop of a hat. I look around. No hat, but I kind of figured out that it meant something that happens immediately, without hesitation, or with very little notice. What Dad didn’t tell me was that in the old days, races, fights, or contests were often cued to begin by the starter dropping a hat as the signal to commence. Once the hat hit the ground, everyone was expected to begin right away. So doing something “at the drop of a hat” came to mean being ready to act, or react, instantly. Mom didn’t need a hat. It was inherent.

There are many more sayings involving hats, and if you put your thinking cap on, I’m sure you can come up with a few yourself. But why would you need a thinking cap? Because … the phrase dates back at least to the 1800s and grew from the older idea that certain hats or caps were associated with scholars, students, judges, or serious study. Smart people wore smart caps. Anything else?

Yeah:

• Old hat — Something familiar, outdated, or no longer exciting.
  Origin: a hat, once new and stylish, eventually becomes worn, common, and unimpressive. By the time it’s an “old hat,” nobody is admiring it anymore—it’s just that thing hanging by the door, collecting dust and possibly judging your life choices.
• Talk through your hat — speaking nonsense, bluffing, or talking confidently about something you don’t really understand.
• .Origin: if a person is “talking through his hat,” the words are not coming from his brain, mouth, or any respectable source of knowledge. They’re coming through his hat—which is to say, from nowhere useful at all.
• Hat in hand — Humbly asking for help or forgiveness.
  Origin: For centuries, men were expected to take off their hats when entering certain places, greeting superiors, speaking to women, or showing respect. So if you came to someone “hat in hand,” you weren’t swaggering in like you owned the place—you were standing there politely, maybe apologetically, with your dignity folded under one arm and your hat in the other.
• A feather in your cap — An achievement or honor.
  Origin: warriors or hunters would place a feather in their headgear to mark a success—often killing an enemy in battle or bringing down game. In some traditions, the feather was not just decoration; it was proof you had done something worth noticing.
