If you had to choose a three-letter name to use for a son or daughter, paired with a longer (preferably 7- to 10-letter) name, what would you choose? One for a son and one for a daughter.
Examples:
Léa [name_f]Marguerite[/name_f] & [name_u]Gabriel[/name_u] [name_u]Max[/name_u]
[name_f]Elizabeth[/name_f] [name_f]Ann[/name_f] & [name_m]Luc[/name_m] [name_m]Nathanael[/name_m]
[name_f]Zoe[/name_f] [name_f]Cecilia[/name_f] & [name_u]Asa[/name_u] [name_u]Benjamin[/name_u]
It depends on the name itself, for me.
Girl:
[name_f]Bea[/name_f] [name_f]Clarimond[/name_f]
Boy:
[name_m]Anthony[/name_m] [name_u]Sol[/name_u]
I like a few 3 lettered names! Because I’m indecisive there are more than two combos but still.
Ptolemy [name_m]Xil[/name_m] ([name_m]Xil[/name_m] is pron. zeel)
Koh [name_u]Atlantis[/name_u]
[name_u]Poe[/name_u] [name_m]Maximilliano[/name_m]
Luminara [name_f]Bellerose[/name_f] [name_f]Eve[/name_f]
[name_f]Phillipa[/name_f] [name_u]Wilder[/name_u] [name_u]Nyx[/name_u]
[name_f]Zatanna[/name_f] Ibelis [name_u]Rio[/name_u]
([name_f]Do[/name_f] double middles count? The girls are all names in my UC cause those have my fav 3 lettered names for girls)
Leo [name_u]Everett[/name_u] …
Kol [name_u]Jameson[/name_u] …
[name_u]Max[/name_u] [name_m]Alexander[/name_m] …
Ava [name_f]Elizabeth[/name_f] …
[name_f]Penelope[/name_f] [name_u]Rae[/name_u] …
Max [name_f]Clementine[/name_f] & [name_u]Kit[/name_u] [name_m]Theodore[/name_m]
Ivy [name_f]Susannah[/name_f]
[name_f]Ava[/name_f] [name_f]Elizabeth[/name_f] @LynnG 
Wes [name_m]Alexander[/name_m]
[name_m]Jon[/name_m] [name_m]Frederick[/name_m]
Asa [name_m]Leander[/name_m]
Noa [name_f]Vivienne[/name_f]
Rex [name_m]Theodore[/name_m] & [name_f]Dot[/name_f] [name_f]Winifred[/name_f]
Liv [name_f]Magnolia[/name_f] and [name_u]Asa[/name_u] [name_m]Frederick[/name_m]
I would choose [name_f]Iva[/name_f] [name_f]Alexandra[/name_f] & [name_m]Christopher[/name_m] [name_u]Asa[/name_u].
Or maybe [name_u]Kaj[/name_u] [name_m]Alexander[/name_m]. I do love me some [name_u]Kaj[/name_u]. Oops for forgetting!
[name_f]My[/name_f] son is [name_u]Kit[/name_u] [name_u]Valentine[/name_u] 
I also love Ivo and Tor for a boy, maybe with middle name Maximilian.
And [name_u]Sol[/name_u] and [name_f]Mab[/name_f] are probably my favourite 3-letter names for a girl, so [name_u]Sol[/name_u] [name_f]Guinevere[/name_f] or [name_f]Mab[/name_f] [name_f]Guinevere[/name_f].
Bea & [name_m]Kip[/name_m] for sure!! Short firsts with long middles are totally my style. I’m not sure of a [name_m]Kip[/name_m] combo yet, but today they’d be [name_f]Bea[/name_f] [name_f]Gwendolen[/name_f] and [name_m]Kip[/name_m] [name_f]Reverie[/name_f]!
Zia [name_f]Winifred[/name_f]
[name_f]Elizabeth[/name_f] [name_f]Fay[/name_f]
Kai [name_m]Evander[/name_m]
[name_m]Augustus[/name_m] [name_u]Fox[/name_u]
Eve [name_f]Marigold[/name_f]/Eve [name_f]Winifred[/name_f]
[name_f]Joy[/name_f] [name_f]Mirabelle[/name_f]/Joy [name_f]Coppelia[/name_f]
Kit [name_m]Hawthorn[/name_m]
[name_m]Luc[/name_m] [name_m]Isidore[/name_m]
[name_m]Hal[/name_m] [name_m]Dominic[/name_m]
Téa [name_f]Benedicta[/name_f]
[name_f]Joy[/name_f] [name_f]Winifred[/name_f]
[name_f]Ivy[/name_f] [name_f]Leocadia[/name_f]
Ned [name_m]Theodore[/name_m]
[name_u]Ara[/name_u] [name_u]Benjamin[/name_u]
[name_u]Gio[/name_u] [name_m]Frederick[/name_m] / [name_m]Geo[/name_m] [name_m]Frederick[/name_m] (can never decide on a spelling for this one!)
Of other 3-letter-names, I also like [name_u]Noa[/name_u], [name_f]Ada[/name_f], and [name_f]Zoe[/name_f] for girls, and [name_m]Zev[/name_m] for boys, though I couldn’t use the later two. Plus I like [name_u]Kit[/name_u] for both boys and girls.
Rex [name_m]Maximilian[/name_m]
Noa [name_f]Clementine[/name_f]
Girl - [name_u]Max[/name_u] [name_f]Elizabeth[/name_f]
Boy - [name_m]Cas[/name_m] [name_m]Ambrose[/name_m]
Ava [name_f]Charlotte[/name_f]
