Ooh, intriguing. I haven’t heard [name_m]Isidore[/name_m] much lately but I feel like it has a very Theodore-like charm. Antique, gentlemanly, and charming. [name_m]Isidore[/name_m] feels slightly more dashing to me, less cozy and more romantic.
[name_f][/name_f][name_f]In[/name_f] terms of spellings:
[name_f][/name_f][name_m]Isidore[/name_m] [name_f][/name_f]- This is the most intuitive spelling to me, the one I’d use if you asked me to guess. I think it’s elegant and has a nice balance visually. I also think this one leans very masculine [name_f][/name_f]- a sort of gentleman image.
[name_f][/name_f][name_m]Isadore[/name_m] [name_f][/name_f]- This one isn’t as intuitive to me, but I do think it’s intriguing. It would likely be mistaken for [name_f]Isadora[/name_f], and for that reason I see [name_m]Isadore[/name_m] as a bit more androgynous. I think this spelling is still more masculine than feminine, but I wouldn’t be as surprised to meet a woman named [name_m]Isadore[/name_m].
[name_f][/name_f][name_m]Isidor[/name_m] [name_f][/name_f]- It’s nice and streamlined, but feels a bit less complete to my eye because I’m more used to the [name_m]Isidore[/name_m] spelling. However, I’ll also say that I picture [name_m]Isidor[/name_m] being a bit more rakish and rugged, while the final e gives [name_m]Isidore[/name_m] a bit more elegance.
[name_f][/name_f]Izidore [name_f][/name_f]- Izidore is my least favorite spelling personally. I think it’s less intuitive and the z doesn’t quite fit with the rest of the name. It’s not bad, and I think depending on sibling names or the naming trends of the area, it might fit in better (ie Izidore and [name_f]Alivia[/name_f] are much better matched to me than [name_m]Isidore[/name_m] and Alivia). I just prefer the other three in terms of vibe.
