Okay you wonderful namers my husband likes [name]Izzy[/name]. Not [name]Isabelle[/name]/a just [name]Izzy[/name].
So do you have any full/longer names we could use to get to the nn [name]Izzy[/name]. This is hypothetical. I am still not sold on [name]Izzy[/name] but I think I may like it more if there was a longer name. [name]Elizabeth[/name]? Carazana?

any help would be great!

Yes, [name]Izzy[/name] seems very childish to me. For some reason I picture it on either a little girl or an adult man- maybe because that’s what all the [name]Izzy[/name]'s I’ve ever met have been. Anyway, I think [name]Elizabeth[/name] works, Carazana is quite a stretch but there are weirder stretches out there (I’m talking to you, [name]Daisy[/name] and [name]Peggy[/name]). Anyway, it could also work for:
[name]Isis[/name] (though it’s prounounced ICE-iss)
[name]Giselle[/name] or [name]Gisela[/name]
