I love [name_f]Persephone[/name_f], but it’s a bit longer than my other names so I’d like a nickname for her to balance it out. I am not fond of [name_u]Percy[/name_u] or [name_f]Posy[/name_f].
I’d like something that isn’t too stretchy, though there’s always room for experimenting. So, Berries, suggest some nicknames for [name_f]Persephone[/name_f]!
Thank you 
[name_u]Perry[/name_u]
Seph
Sephy
[name_f]Poppy[/name_f]
[name_u]Penny[/name_u]
[name_u]Sonny[/name_u]
[name_u]Poe[/name_u]
[name_f]Nonie[/name_f]
[name_f]Effie[/name_f]
[name_f]Queenie[/name_f]? (queen of the underworld)
I love [name_u]Pip[/name_u] or [name_f]Pippa[/name_f] as a nickname for [name_f]Persephone[/name_f]! Seconding [name_u]Penny[/name_u]. Maybe [name_f]Sophie[/name_f] or [name_u]Sunny[/name_u]?
[name_u]Poe[/name_u]
Sephie
[name_u]Peri[/name_u]
Pez
Phee
[name_u]Pepper[/name_u]
You’ve got tones of good suggestions (Effie, Seph, Queenie…)
What about [name_f]Kore[/name_f] / [name_u]Kora[/name_u] / [name_u]Kory[/name_u], which were Persephones nn in mythology l✨
I was thinking of [name_f]Kore[/name_f] too
@Johannaa [name_f]Poppy[/name_f], [name_u]Penny[/name_u], [name_u]Poe[/name_u] and [name_f]Effie[/name_f] (!) are adorable.
@wishmay [name_u]Pip[/name_u], [name_f]Pippa[/name_f] and [name_u]Sunny[/name_u] are wonderful.
@Greyblue I love [name_u]Poe[/name_u] and [name_u]Pepper[/name_u]!
@tonguetwisted [name_f]Pippi[/name_f] and [name_f]Fifi[/name_f] are cute. I like [name_f]Peppa[/name_f] too but it reminds me (and sadly, many others) of [name_f]Peppa[/name_f] Pig.
@bemiranda & @Eirime [name_f]Kore[/name_f] / [name_u]Kora[/name_u] is amazing, never would’ve thought of that!
Thank you for your brilliant responses! 
A little late, but I love [name_m]Finn[/name_m] as a nn for [name_f]Persephone[/name_f]!
