Like @lumen, I also very much believe your nn does not have to depend on your given name. If you want a nn that follows easily from [name_m]Felix[/name_m], [name_u]Finn[/name_u] is not a great choice. However, that does not mean you cannot still nn him [name_u]Finn[/name_u]. If you love it as a nn, you can use it regardless of his fn.
[name_m]Pheonix[/name_m] nn [name_u]Finn[/name_u] flows more obviously than [name_m]Felix[/name_m]. The sounds are more similar with [name_m]Pheonix[/name_m] and [name_u]Finn[/name_u] - with the -f and the -n sounds.
[name_m]Felix[/name_m] nn [name_u]Fee[/name_u] flows obviously because the sound fee sound is present in the first syllable of [name_m]Felix[/name_m]. Feen also has that in common, but the ending differs.
Since you suggested changing [name_m]Felix[/name_m] to [name_m]Pheonix[/name_m] to achieve nn [name_u]Finn[/name_u], I am wondering if you actually prefer [name_u]Finn[/name_u] to [name_m]Felix[/name_m]. If you plan to call him [name_u]Finn[/name_u] specifically, and are not just searching for an agreeable nn, I would just name him [name_u]Finn[/name_u].
[name_m]Hi[/name_m], I was thinking, why don’t you spell out the name [name_m]Fin/name_m with his full name? Ie [name_m]Felix[/name_m] [name_m]Isaiah[/name_m] [name_u]Noah[/name_u] - ok that combination doesn’t really go together but they were the first names that came to me! My son has the initials A G R O - we are yet to call him Agro (he’s 22 months) but we thought it was a funny play on names which included family names & his pop [name_u]Owen[/name_u] (the O name!) was called Agro by his dad’s teenage friends so it was a tribute to him as well. Anyway just a thought if you really like the name [name_m]Felix[/name_m] but are wanting to nn him [name_u]Finn[/name_u].
@melndrew, that’s a brilliant idea. I agree with everyone else that [name_u]Finn[/name_u] is a name in its own right and doesn’t relate to [name_m]Felix[/name_m] – it would like naming your baby [name_m]Robert[/name_m] and calling him [name_u]Ray[/name_u], creating lifetime confusion – but if you name him [name_m]Felix[/name_m] [name_m]Isaiah[/name_m] [name_m]Nicholas[/name_m], you’ve created a reason for him to be called [name_m]Fin[/name_m].
[name_u]Love[/name_u] [name_m]Fox[/name_m] too. [name_m]Fox[/name_m] is so much better than [name_u]Finn[/name_u]!
[name_u]Finn[/name_u] is a great name, but it’s NOT a nickname – it is a full and historic name in its own right – and if you really want it to be short for a longer name, there are so many that fill that bill, from [name_m]Finnegan[/name_m] to [name_m]Finnian[/name_m] to [name_m]Phineas[/name_m] to [name_m]Griffin[/name_m].
But [name_m]Felix[/name_m] is a great name too. Let him own it!!
I have the same problem as the other posters… [name_u]Finn[/name_u] is a NAME, not a NN.
If you don’t really like the nicknames for [name_m]Felix[/name_m] why not use a REAL nn.
Here is a list of true nicknames where (unlike with [name_u]Finn[/name_u]) you will ALWAYS be asked “What is his real name?”
[name_m]Ace[/name_m], Boots, Bunky, [name_m]Butch[/name_m], [name_m]Flash[/name_m], [name_m]Jeb[/name_m], [name_m]Laddie[/name_m], [name_u]Rex[/name_u], [name_m]Ringo[/name_m], [name_m]Skip[/name_m], [name_m]Skipper[/name_m], Skippy, Slugger, [name_u]Sonny[/name_u], [name_m]Zeke[/name_m]
