A quick web search shows that this isn't the origin of the @ symbol. The wikipedia page gives older accounts of the symbol and says that its not clear where it came from.
I use "ALT" + "L" for @
monkeys tail, never heard of in Germany. Just at
In Greece they call it "papaki" ("the little duck")
❤
I’m never calling it “at” again… it’s officially the “snail” now 🐌😂
Wowie❤
I'm so glad I found this channel
This was so informative! I love this channel so much 🙌🏾☺️
In Greece we call it little duck😂
Please make video about Internet data pack and how they work as currency😊😊
Interesting.
I never met any German calling it Monkey's Tail. I have met one of two Germans calling it "Schnirpfelschnurz" though. All the others I met just call it "at".
Fascinating as always…….. Thank you
IIRC, I learned in typing class 40 years ago that it was a lower case ampersand. Which makes sense given that it originally represented an “amphora” of wine.
Делаю реферат по этой теме. Пока искал информацию, нашел множество вариантов происхождения @ (кстати у нас в России его называют "собака А"). На сайте bbc видел, что самое раннее задокументирванное появление этого символа в значении меры веса (или амфоры) было не в 1536, а почти на сотню лет раньше.
Но самое ранее появление @ примерно 1340-е годы. Правда там это была просто красивая закорючка 🙂
Wow! I learnt something new today. keep the good work up
It is also called a shtrudel
Wow@
In Greece, it's called a duckling! Not because it looks like a duckling – which it doesn't… It's because it looks like a testicle, and the slang word for this, is almost identical to duckling 😂
In France it is called arobase
I don't use @ to log into websites. I just type the name
In French, it is not called saillant or escargot but arobase, which relates to anciens printing characters.
in Spanish is called " arroba "
Very cool info.😍
