Spanish and Italian have a few funny ones:

Burro: Donkey (Spanish) / Butter (Italian)

Porro: joint (of weed, you know) / Leek

Orto: Ass (not everywhere, but where I lived, it had that meaning) / vegetable garden

There’s probably more, but these come to mind now.

To add a funny one:

(Hint for Americans: the joke makes more sense if you pronounce it with a British accent)

One of my favorites are the chains between Spanish and Portuguese:

• Garbage in Spanish is Basura
• But Vassoura in Portuguese means broom
• But in Spanish broom is said Escova
• Which in Portuguese means brush

Or

• Tea cup in Spanish is Taza
• A Taça in Portuguese is a wine cup
• But in Spanish wine cup is a Copa
• And in Portuguese a Copo is a regular glass
• But in Spanish regular glasses are called Vaso
• Which in Portuguese means vase.

Or

• Cutlery in Portuguese is Talher
• But Taller in Spanish is a workshop
• Which in Portuguese is Oficina
• Which in Spanish means office
• But in Portuguese you say Escritorio
• Which in Spanish means desk

Or a short one:

• Your last name in Portuguese is your Sobrenome
• But in Spanish Sobrenombre is your nickname
• While in Portuguese nickname is Apelido
• But in Spanish Apellido means last name

Another one I like is Vamos a chatear 1 rato which in Spanish means “let’s chat for a little while” but in Portuguese means “let’s bother a mouse”.

If I understand your question correctly, between English and Italian is “camera”. In Italian it means “room”, not a device for photographs.

English/german has Gift and Die.

Probably others but idk.

It’s not just in different languages, but sometimes in different variants of the same languages.

For instance, in Belgian French, “tournante” is any task in which people take turn, like a card game. In French French, it’s specifically gang rape.

And then you have words that aren’t spelled exactly the same way but seem like an obvious translation (actual false friends, which aren’t usually exact matches), like the Spanish “constipado”, which means to have a stuffy nose and not what you think.

The Scandinavian languages are very similar and we can usually understand each other pretty well just using our native tongues, though there are some funny traps and false friends. Norwegians are entertained that in Sweden we drink “bärs” (beer), because it sounds exactly like “baesj” (shit). And are astounded that we can “pula” with almost anything, as in “tinker/fiddle around” in Swedish and “fucking” in Norwegian. Oh yeah, a Norwegian ex gf found it hilarious that we have “rågkusar” (a type of rye bread) in the stores, as “kusa” in norwegian mean “cunt”. Also in Swedish a common slang word for shoes is “dojor/dojer”, which on the west coast of norway is very similar to “daejer” that means tits. So don’t go in a shoe store asking for a nice pair of “dojer” unless you know exactly what you are doing.

On a sidenote, I must give credit to the best Swedish word I know; “Skamsköljning”. Literally “shame-rinsing”. As in remembering something stupid you did and the feeling of shame washing over you. In Norwegian it is probably “pule-svejs”, fuck-haircut. The funny hair you have after a good banging.

Preservative is common for eng and french

¯\_(ツ)_/¯

I remember the Czech word Pozor. It means “Attention” and is seen everywhere on all sorts of signage.

In Russian, however (and possibly other slavic languages), it means shame/disgrace.

I’m sure there were jokes about it when Russians were the invaders, but can’t remember any.

Then there’s Finnish/Estonian

But my favorite is “nahkhiir”, which means leather mouse, i.e. a bat. (in Finnish it would be nahkahiiri, but bats are called lepakko)
Batman is consequently called Nahkhiirmees in Estonian.

The one that springs to mind is the German bekommen v the English to become.

EN DE

to become werden

to get bekommen

They are basically the same word and at one point might’ve meant the same. Now there is no common meaning.

Mood

Actual. English: real. Spanish: current

Sensible. English: reasonable. Spanish: sensitive

In German, we’ve somehow adopted the English word “Handy” to refer to mobile phones. Problem is, if you actually use it as a noun in an English sentence, it’s a slang word for “handjob”. 🫠

Greek: Ναι (ne) means yes. Greeks often move their head up and down to say yes.
Bulgarian: Не (ne) means no. Bulgarians often move their head up and down to say no.

So if someone says ne and moves their head up and down it could be a Greek saying yes or a Bulgarian saying no. In reality the movements are not the same but it would probably be confusing to an outsider.
