What I think is interesting about the word flea market is that it's a calque in pretty much all languages.
The Swedish word is "loppis", which is a cutesy colloquial term for "loppmarknad." Loppa, meaning flea, and marknad meaning market.
Flohmarkt in German also means lit. "flea market."
Marche aux puces is French, where "puce" means flea, I think this might be the origin of the term.
Japanese has the casual term フリマ (fleama), short for フリーマーケット, which is just the English term "flea market", there's also the term 蚤の市, just meaning "market of fleas."
I believe Portuguese calls it a "thieves' market", but Spanish, Italian, Russian, Turkish, Dutch, and Mandarin all use their own native words for "flea market"; mercado de pulgas, mercato delle pulci, Блошиный рынок, Bit Pazarı, Vlooienmarkt, 跳蚤市场.
For all of the concepts and such that are identical across cultures, few things have universal names. Typically they enter the language as loanwords as well (e.g. karaoke, from Japanese '空オケ', hollow orchestra), so the term "flea market" stands out to me. I'm sure there are lots of other similar things I'm not aware of though.
Edit: It's worth mentioning that other than Swedish (native), English, and Japanese, I don't speak any of the other languages. I've asked a Russian-American friend about the Russian term, and a friend in Taiwan about the Mandarin term. Otherwise I've checked dictionaries and the like. Don't take my word as fact, I'm not a linguist. It was just a pattern I found interesting, because the term itself is so particular. Any and all corrections are more than welcome.
I'm also delighted by the discussion this has sparked! 💖
That reminds me of the word 'Frank,' which was used by the Byzantines to essentially mean 'all those non-Roman barbarians to the west of us' and which, after the Crusades, spread as a word across Asia meaning 'Europeans.'
Thank you for sharing! I had not heard of this before. I particularly enjoyed this bit
Farang khi nok (Thai: ฝรั่งขี้นก, lit. 'bird-droppings Farang'), also used in Lao, is slang commonly used as an insult to a person of white race, equivalent to white trash, as khi means feces and nok means bird, referring to the white color of bird-droppings
That's so colourful. I love it.
It also made me think of the fictional race in Star Trek, the Ferengi. At least according to Wikipedia that is precisely the origin of their name!
This is true, I don't know which word came first. I'd wager a guess that 蚤の市 predates フリーマーケット, but it's really just a stab in the dark on the basis that English loanwords feel more modern, and it feels unlikely that a calque would be created after a loanword has been widely adopted.
Is tori ever used like plaza, like the Swedish word "torg?" The way I read tori in my head makes it sound almost homophonous with torg, hence why I ask.
A number of Slavic, Baltic, Norse, (and also Finnic languages like Finnish and Estonian) use some form of this word for market. It originated in Proto-slavic and passed through Old Norse into descendant languages.
The most interesting thing is that the root appears to have borrowed into Finnish twice, once probably from Slavic (as turku) and once from Old Norse (as tori).
"Hippopotamus" is another one. It derives from the Greek words hippos (horse) and potamos (river) and this concept of river horse is present in many different languages:
German: Flusspferd (lit. river horse)
Dutch: Rivierpaard (lit. river horse)
Finnish: Virtahepo (lit. stream horse)
Danish: Flodhest (lit. flood horse)
Chinese: 河马 (lit. river horse)
Arabic: فرس النهر (lit. river horse)
French, Spanish, Italian and Portuguese use variations of hippopotamus.
Actually, the Dutch translation is "Nijlpaard", not "rivierpaard".
But, it uses the Dutch name for the Nile river, "Nijl". So it's lit. "Nilehorse" - which is technically the same as "river horse", just more geographically specific.
Unimportant extra: it's not a calque in British English, because we don't use it (to the best of my knowledge). Like a potluck, we have the concept but not a word for it, and we don't use the American phrases either
It’s almost like most of those languages you mentioned, had their speakers go everywhere around the world, approximately 500 years ago, and they colonized most of the world, causing many places around the world to use similar idioms…
