Dionysios

Congratulations!
I think if you don’t want to go for some of the more common examples like Nikolas, Giannis, Iasonas, there are some nice ones you can consider..

• Dimosthenis (Dimos)
• Dimitrios/Dimitris (Dimos, Takis, Mitsos, Jimmy)
• Alexandros (Alekos, Lex)
• Kyriakos (ruined for me due to the current most famous Kyriakos in Greece, but I used to think the name was nice)
• Eleftherios (Leftheris) - Related to free, freedom
• Panagiotis (Panos, Notis, Takis)
• Stylianos (Stelios)
• Miltiades (Miltos)
• Orestis/ Orestes

This will not be news to you, given that either yourself/your partner is Greek, but I think it’s nice to consider both the way the nickname would be Anglicised, and also the Greek way of using the diminutive version of the name, eg: (Konstantinos>Kostas). I don’t know how much time you’ll spend in Greece/around Greek speakers but this might have a bearing with Dionysios , where naturally people would default to Sakis, Denis, (maybe Nionios for some older Greeks) and it might be hard/er to make your chosen nickname stick.

Lastly I think most (non-religious) Brits will always assume the ‘Greek myth’
version of the name but I don’t think that means your name is as ‘outlandish’ as some make it sound, especially for the large part of the world familiar with Catholic or Orthodox tradition.

All the best for a healthy and happy baby!

No, it just doesn’t work - even the nickname. The prevailing English pronunciation starts with die not dee, so you’d get Dio not Deo. And Deo means god to a lot of people, which unfortunately would make you sound like a bit of a twat for calling your kid God.

I’d go for something normal, like Apollo, Atlas, Damon, Hector or Paris.

Dio would be very cute!

Lysander has potential and think fits your criteria?

I love it! It’s a strong name and love the shortened version too. I also love Anthony, Christian, Stefanos and Giorgios.

Go for it! If you like it, it doesn't actually matter what a load of non-Greek, conservative name choosers think. I think it's great and that more children should have big, bold names! I just had to post a big that someone suggested Adonis as an alternative though 😂

Love it! Go with it.

Lysander is one of my favourites.

Other than that , Orion, Leon, Atticus , Dorian, Leander/Leandro , Demetrius.

Dio is a great short version, and he’d only have to use the full name occasionally . I think it’s a good choice.

I'm not too keen OP, it's too much of a mouthful for me.

The greek boy I know is called Agalos which I like. Also love Dimitrios and Asterios. Beautiful names.

There are different variants. I’d pick one and presume people would learn. Maybe I’m being too optimistic.

You probably are. DD has what I think is a fairly regular English/French name. Not Top 100 but we've met others along the way. You'd be surprised just how many people seem to struggle with spelling her name.

Go for it OP, incredible choice. Hope baby lives up to it.

All i can think of now when I hear Dionysus is the naked blue guy from the Paris Olympics opening ceremony. Personally I wouldn't name one of mine something that can be spelt so many different ways, is a bit of a mouthful and is the god of wine.

Personally I like Lysander as a boys Greek name.

I love it. And Dio for every day is a great name. My DD has a longer unusual name from her ancestral heritage and a shorter every day name and it's never been an issue. I would go for it.

I’ve met people in Latin America with the Spanish version of this name and it’s used in Italy too. Uncommon, but certainly not weird. I like it very much!

Bear with me as I have a half memory but I'm hoping the Mumsnet mind will know what I'm on about. There's a Greek series, probably on Netflix but I'm sure it's not kaos but I'm sure it's based on Greek mythology. There's a bunch of rich spoilt kids and one has a name that starts with P. I'm think it's prospero. It's been a while and I don't plan on any more kids so I forgot about it but I thought it sounded really good and kind of worked in modern life.

Dionysus was a famous rapist. There’s few in mythology who aren’t predators.

I like Dionysus(with nn Dio or Dion)
Do any of these appeal?

Aithan
Milos
Atlas
Elias

Asterios is really lovely. I also love Nestoras and Zephyros.
how about:
Vassilios
Aristides
Iacovos
Eleftherios
Nikodemos
Leandros
Themistoklis
Emilios
Argyris
Kosmas
Pericles
Gerasimos
Chrysanthos

If the top half is Greek then perhaps Herma, but if it's the bottom half then Achilles.

Presumably the other half will have a different name?

I can see problems here...

Wouldn't Dio be pronounced as Dy-o - Like Lady Di?

Problem with shortening it to Dio is that it means God (as in The God) in Italian - Spanish it's Dios. Obviously like us they use it as a lesser sweary word too. That would put me off in multicultural London.

The Greeks I know - Panos, Dimitri, Alexander, Yannis - I know these are spelt wrong/shortened but you get the jist

You are being very optimistic! I’ve had over 50 years of having my name spelt wrong and it’s bloody tiresome - especially in the digital age where I miss emails because people don’t spell it right 🤦‍♀️.

I think there are other options that are better - and less challenging!

I've not heard Iason mentioned?

I like it. I like strong names. Brits will be more familiar with Dionysius or Dionysis* *if that's important to you at all?

Other Greek names? I've always liked Andreas.

I love it and love the nickname.
