Eyeliner, Gravel and a Typo

I recently spoke at King Fahd University of Petroleum and Minerals in Saudi Arabia. Standing in front of that audience, it struck me how much of my own language I’d borrowed from theirs without ever asking.

Start with a drink. Alcohol comes from the Arabic al-kuhl: kohl, the fine black powder used to darken the eyes. Alchemists used the word for any very fine powder, then for any substance refined to its essence. By the 1600s it meant pure spirit. It wasn’t until the 1700s that it settled on the stuff in your glass. So the word for what’s in a gin and tonic started out as eyeliner.

Look up. Zenith, the point directly overhead, comes from the Arabic samt ar-ra’s, “the path over the head”. Medieval scribes shortened it to samt, then misread the m as ni. Samt became senit, and senit became zenith. One of the loftiest words in English is a copying error.

Count to nothing. Arabic sifr meant “empty”. It translated the Sanskrit word for the same idea, and travelled into Europe with the numerals we still use. It arrived in English twice. Through one route it became cipher. Through Italian it became zero. A cipher and a zero are the same word, which is why “a cipher” can mean a person of no importance.

Then there’s the maths itself. Around 820, the Baghdad scholar al-Khwarizmi wrote a book on solving equations with al-jabr in its title, “the reunion of broken parts”. That gave us algebra. His own name, Latinised, gave us algorithm. Every app on your phone runs on a Persian mathematician’s name, passed down through Arabic and Latin.

And sugar in your coffee? Coffee comes from the Arabic qahwa, via Turkish and Italian. Sugar came through Arabic sukkar, but Arabic was only a stop along the way. The trail goes back through Persian to the Sanskrit śarkarā, which originally meant grit or gravel. Your sweet tooth is named after gravel.

This is what language really looks like. Words don’t stay where they’re born. They travel with trade, conquest, scholarship and recipes. They get misread, shortened, repurposed and passed on, until nobody remembers where they came from.

It’s a useful reminder for anyone who thinks of their culture as self-made. Our maths, astronomy, chemistry and breakfast all carry Arabic fingerprints. That’s not a political point, it’s an etymological one. The words are the receipts.

Next time you order a coffee with sugar, think of a Baghdad mathematician, a scribe’s typo and a pot of eyeliner. English borrowed all of them.
