Thank you. How do modern Greek speakers pronounce the ancient words? With the new sounds, or the old sounds? Are there many ancient words in modern Greek?

I do not know if this remains true nowadays, but in the past most Modern Greek speakers pronounced the ancient words with the modern pronunciation, because this is how it was taught in schools, despite the fact that the Ancient Greek pronunciation was very different. This is the same like with the Latin language used by the Catholic Church, which traditionally had a modern pronunciation very unlike Ancient Latin, or…

Thank you! As a speaker of another ancient language, this is very interesting.

The Japanese specification for the color of traffic lights is certainly written in Japanese. If the specification says the light should have color "ao", then either blue or green or something in between that matches it is OK. That the color region that word encompasses doesn't match that of the English words "green" doesn't really matter, and is not particularly mysterious.

The article talks about the specification and it's more... specific than that: > “In 1973, the government mandated through a cabinet order that traffic lights use the bluest shade of green possible—still technically green, but noticeably blue enough to justifiably continue using the ao nomenclature,” Allan Richarz writes for Atlas Obscura.

So there was an intentional decision to adjust the lights to their conceptual preferences. Assuming someone can source this 1973 cabinet order.

Not a linguist. I feel like this is just an issue of imperfect correspondence between the word "blue" in English and "ao" in Japanese. The article explains the historical reason why ao encompasses both blue and green, so I think the concept of semantic field comes into play here. As an analogy, a MacBook is a type of laptop, and laptops, desktops and tablets are all IT devices (for lack of a better word). Apple might…

I trained as a linguist and you hit the nail on the head. Word meanings are fuzzy clouds of references and nuances, and every language has slightly different clouds. There is nothing magical about this, despite the recurrent lizard-brain notion that words or names are somehow mystical and intrinsic, and that these differences must somehow be meaningful. Differences are quite common with colour terms - you don’t need…

> I assure you I see these colours the same as you do.

I assure you that you do not. Don't want to get too philosophical or biological on you but we all see colors differently. Every single one of us. Even identical twins.

It's a nice article and has lots of details. But I searched my photo history for Japan and here are the first few that have traffic lights in them: https://imgur.com/a/S815y7o This should help you determine what colour the lights are in your perception. Some are taken with a Canon DSLR and some are taken with a Pixel 3.

Nice photos!

Thank you :)

I think the most common real-world example is Russian and Italian, which have a specific word for light-blue which is distinct from the word for blue. I assume this is like how ‘pink’ is a special word for ‘light-red’.

You see the same thing in other areas. In Mandarin Chinese, the sounds represented by "si" in English vision or "r" in English virile are the same sound. An English speaker (like speakers of many other languages) would find this ridiculous, but it is true that the two sounds represent either side of a completely arbitrary threshold applied to a continuous phenomenon.

It's like in English the sound represented by "ś" in Polish "ściągać" and "sz" in Polish "szumieć" are the same sound (usually written "sh") :).

Grue is a fascinating concept and it's much more pervasive than Japanese: https://en.m.wikipedia.org/wiki/Blue%E2%80%93green_distincti...

Especially the fact that it tends to impact the speakers ability to perceive shades of the color.

Do you know more about the history of this color use? It’s surprising to me that midori uses the kanji for green in Chinese if it’s such a recent idea in Japan.

I don’t know about the green kanji, but the traditional “Jueju” Poem by Chinese poet Du Fu has the line “山青花欲然”, and “青” the Kanji for Blue in Japan means green in this context, as it describes “山” which means mountain. By the way there’s a variety of kanji that reads “aoi” in modern Japanese. 青い, 蒼い, 碧い are all “aoi”, but we use 青い mainly as blue today.

Oh that’s interesting. Yeah 青 is used in Chinese as another word for green. I don’t know that it has any connotations of blue, but I did grow up in the US, so perhaps there’s nuance to that character I’m unaware of, or the character slightly changed meaning when made a kanji.

It's juice of the fruit-called-orange. How is that not orange juice? We don't call apple juice "red juice" or grape juice "purple juice". If there's a language in the world where the color and the fruit aren't the same word, I've yet to learn it.

No one's disputing that. What's funny is that most people don't seem to realize that that the color of the juice isn't the color of the rind. Just look at illustrations of orange juice on Google Images: https://www.google.com/search?q=orange+juice+illustration&tb... Most of them are showing an orange liquid that matches the color of the orange rind. It's hilarious. Because somehow, most people don't realize orange ju…

A perverse feedback loop has clearly emerged. It seems that in the US at least, "To further enhance color, manufacturers add up to 10 percent vividly colored mandarin orange juice as well as pigment from orange peels." [1] Further, it seems that juice colour is actually designed and kept consistent. [2]
