My two thoughts at the moment are [name_f]Sera[/name_f] or [name_f]Siri[/name_f].
[name_f]Sera[/name_f]… I like it in theory, but not 100% sure as it sounds a lot like [name_f]Sarah[/name_f], which I really dislike. I’d be worried people would hear it that way and actually call her [name_f]Sarah[/name_f].
[name_f]Siri[/name_f]… I really like it, and the phone thing doesn’t really bother me given it is a name in its own right. It doesn’t exist purely because of the interface. I also love that the meaning “beautiful victory” pairs so well with the meaning of [name_f]Saoirse[/name_f], which is “freedom”.
…And yes, I know it works well as a whole name and it doesn’t need a short version, but I’m very much a pet name person, so I’m just looking for ideas.
[name_f]Suri[/name_f] (Idk how to spell it, but take the first syllable of [name_f]Saoirse[/name_f] and add an “-ee” to the end) sounds more like a pet name than [name_f]Sera[/name_f], which sounds like a standalone name, in my opinion.
I like the idea of [name_f]Siri[/name_f] and the previous mentions of [name_f]Sisi[/name_f] & [name_m]Sash[/name_m]. The only other options I can think of that haven’t been mentioned yet are Seer & ChaCha!
My favourite nickname for [name_f]Saoirse[/name_f] is [name_f]Suri[/name_f], but from your list I like [name_f]Sera[/name_f]. It does sound a lot like [name_f]Sarah[/name_f] but the EER-ah over [name_f]AIR[/name_f]-ah makes it different, although only slightly, so I wouldn’t assume the name was [name_f]Sarah[/name_f].
I think I’m a fan of [name_f]Sisi[/name_f]… not 100% sure, but it’s probably nicer than some other options. I like how it sounds, but I’m not sure about the applied connotations though (in Australia anyway).
