She doesn't speak English - pointless meeting up

This is a good opportunity for you, then!

She will have enough 'cross over' words in those three languages to understand a lot of what you say without being able to speak English.

The commonality within French, German and Italian with English is pretty high.

She WILL understand a lot of what you say and she will have foreign words with similar meanings that she can use that you will understand.

Trust me. You will be able to have a vague conversation with her even if she doesn't speak a word of English (which I suspect she will).

Jesus….

How about you buy her these as a gift. They might not be brilliant (the reviews are good though) but it might break the ice and be a bit of fun

No excuse at all.

My dad is English, my mum is Dutch. He spoke no Dutch and my grandmother spoke no English. They still managed to communicate.

Of course you should meet.

Can you not speak any French or German yourself? Even a few words of greeting? Get yourself on Duolingo in the interim.

So she speaks Italian, French and Swiss German?
If she speaks German then she'll understand some English, I imagine, as there's similarities.
Could you learn a few phrases in one of her languages? Hello, nice to meet you. I don't speak [insert language] but [insert brother name] will help us out.

Exactly. Perhaps the OP has never travelled or met anyone non English speaking before. It seems strange, though.

Im going to go against the grain a small bit here. I wouldn't meet them for dinner , maybe a coffee instead might be less awkward and of shorter duration 😅

The languages she speaks have enough commonality with English you’ll be fine. It’s not the UN with contemporaneous translation of every utterance needed.

You are going to avoid meeting her because she doesn't speak English? Have you never been in this situation before?
Go a long, be friendly. Listen to your brother and his translation.

She is still a human being!! If they ever have children with your attitude you won’t be able to complain if they cut you out completely.

You sound like Nigel Farage

Completely unreasonable. Life is not always about what you want to get out of it. We have to do things we don’t want to do at times.

Try and empathise. Imagine you’re her in this situation and what you might need to feel comfortable, safe and connected.

A warm smile and a hug can go a long way into welcoming someone but simply turning up is the best start and the most respectful thing to do.

Wow. Sounds like you’re already jealous of your SIL and looking for reasons not to engage.

How nasty. Be a better person OP.

You're xenophobic.

My grandfather's third wife was effectively the only grandmother I knew growing up.

Neither of us spoke the same language. To compound it, my grandfather didn't speak her language and she didn't speak his (don't ask me how that really worked as being married is a whole different level!). They were together more than 15 years before he died.

It didn't matter. We had conversations despite this. It sounds crazy but we did. And we understood each other despite the language difference.

It's surprising how much communication is non verbal and how little of another language you need to be able to understand meaning. Stuff like emphasis and body language is hugely important.

You have nothing to lose by meeting up. You could learn a lot. It might be a disaster. But your brother will appreciate it and she's more likely to see a benefit to learning English if you do meet.

Honestly I find your tone and comments exceptionally narrow minded and bigoted.

How many languages do you speak?

Blimey !!! Maybe OP you could just shout louder in English if she doesn’t understand? Surely that’s how the Brits do it best!?

Why on earth should all other nations learn English? Times have changed .

Or you could smile, laugh use facial expressions, gestures, brother translating . And maybe even learn a few words of her language. Like “I’m pleased to meet you, how are you? “

This. Make an effort.

I can as someone who is married to a dh who doesn't speak my mother tongue.

Smiles.
Shake her hand/ hug on meeting
Lifting up dishes towards them and offering
She may not know the word for Good/great but she (and you) will likely understand Magnifique so use that to show you enjoyed it. Some words are more universally known.

Open body language not hunching up in a corner during dinner. Relaxed position.

Make eye contact when she tries to commuicate with you. Look at her when she speaks even if you have to wait for your brother to translate. Once bro has translated look at her as you reply. You are having a conversation with her not bro.

And you know show her silly penguin shorts dog cat whatever floats your boat for funny if she likes it too.

Dont speak slowy and loudly. Its so weird. And doesn't make the person understand ypu any better.
Speak slower when you use the language you know a bit but not excessively so. Like when you want to clearly pronounce something.

Don't do an exaggerated point towards your mouth as if asking if she is hungry it comes across as patronising.

Be open minded. One of my close friends married a Japanese woman. For their wedding her family and I were in the same hotel they spoke no English I no Japanese we managed as we were both willing.

A lot is your attitude. My family love dh we have been married 34 years next week. He has learned some of my 1st.language mainly a beer please and mother in law. My family like him.

When Gernan people say they don't speak English it means either of two things - they do speak it, very well, OR they really don't because they were brought up in a time when Russian was the second language and any English they were taught has never really been used.
One of my favourite actors started a video by apologising for his 'bad English' because he was 'from East Berlin' but then went on to speak very good English, albeit with an accent. He is technically from East Berlin however was 7 or 8 at the time of unification and would have learnt English at school.
I realise this is an aside.....🤣

Some do choices. Not everyone has English. I did English, my friend did German. She does not speak English past "hello, how you?".
Like not everyone in UK speaks French, innit

You're judging someone for speaking the 'wrong' three languages?

I think you need to have a think about why you have such an issue about this situation.
