I see people frequently write that they would pronounce this name like [name_u]Evelyn[/name_u] with an a at the end. This has been coming difficult for me to pick up because since discovering the name I have always said it like [name_f]Eve[/name_f] with [name_f]Lina[/name_f] tacked onto the end, I also think it sounds much prettier and delicate/dainty this way and I feel the sound matches up better with the frilly look. But nobody else (literally) that I have seen is saying [name_f]Evelina[/name_f] this way and it’s a shame in my honest opinion but to each their own.
This is simply something I’ve always wondered about and today for some reason it has really begun to bug me so I thought I’d throw it out there and ask: how would you say [name_f]Evelina[/name_f]? And if the way you say it is the [name_u]Evelyn[/name_u] + letter a way then why & would you or would you not ever switch to the [name_f]Eve[/name_f] + [name_f]Lina[/name_f] way?
I would say ev-uh-LEEN-a
I say it a different way all together!
[name_u]Evelyn[/name_u] + a = eh-vuh-LYNN-uh
[name_f]Eve[/name_f] + [name_f]Lina[/name_f] = eev-LYE-nuh
But [name_f]Evelina[/name_f] is eh-vuh-LEE-nuh!
I say it ev-uh-LEEN-a
this is how i say it too!
there’s a youtuber named sj strum who’s daughters name is Evelina pronounced how Hazel said! :))
For me it’s:
[name_u]Evelyn[/name_u]: Eh-vah-lyn
[name_u]Evelyn[/name_u] in Spanish is: Eh-veh-LEEN
And [name_f]Evelina[/name_f]: Eh-veh-LEEN-ah
I’ve never thought about pronouncing it like [name_f]Eve[/name_f] + [name_f]Lina[/name_f] because it looks to me like it should rhyme with [name_f]Adelina[/name_f], if that makes sense. 
Evelina: eh-vuh-LEE-nuh
Evelyn: EH-vuh-lihn
Evelyn with an a: eh-vuh-LIHN-uh
I pronounce [name_f]Evelina[/name_f] as eh-vuh-LEEN-ah. I wouldn’t pronounce it as eve-lina unless I was asked to.
But I will add, I pronounce [name_f]Jamesina[/name_f] as jeh-ma-SEEN-ah and basically everyone else I’ve seen pronounces it as james-een-a! And I think my way is nicer lol.
I’ve known a few Evelina’s, they all pronounced it eh-vah-LEEN-ah
Ehv-uh-lee-nuh so beginning is like [name_u]Evelyn[/name_u] but the end is lina instead of lyn+a. I think the first E is sometimes said ee like [name_f]Eve[/name_f] in some languages so I wouldn’t be surprised to be told some one wanted ee-vuh-leen-nuh but the middle e is always an uh to me so eva+lina sure, but eve+lina eeev-lee-nuh with three syllables is not something I’ve ever heard. It does sound nice though, so if someone corrected me to that I could get on board but it would never be my first or second guess.
I’d say it Ev-uh-lee-nuh, as that’s how I heard it said first, and the way I find prettiest.
Eve-leen-uh is pretty too, and I’m not averse to it. But then, I like [name_u]Evelyn[/name_u] pronounced eev-lin so 
I like your explanation best. Eh-vuh-LEEN-ah sounds nicer than eh-vuh-lyn-a for sure. Seeing as how everyone would never begin to guess it’s pronounced eve-LEEN-ah I’m going to have to tailor the way in which I say it and eh-vuh-LEEN-ah I don’t actually mind so perhaps it’s a matter of getting more used to it this way in order to avoid mispronouncing it at first
I would pronounce this eve-lee-nah.
Definitely eh-vuh-LEEN-ah.
eev-leen-ah sounds a bit awkward and nasal to me…I’m also not sure about [name_u]Evelyn[/name_u] with an -a at the end, as a girl’s name it’s usually pronounced EV-uh-lin so that would make it EV-uh-LIN-ah or EV-linna? The EVE-lin pronunciation would get you EVE-linna, but that’s less common (a bit more upper crust and gender neutral).
Wow this is the first time I’ve seen someone with my same intuitive pronunciation
eh-veh-LEE-na. Not [name_u]Evelyn[/name_u] + a, as I pronounce [name_u]Evelyn[/name_u] as EEV-lin. eh-veh-LEE-na is (or an approximation) is how it’s pronounced in every language, because it’s not a combination of [name_f]Eve[/name_f] and [name_f]Lina[/name_f], it comes from [name_f]Aveline[/name_f] (which comes from [name_f]Avelina[/name_f], which comes from Avila).
eh-va-lee-nah !
[name_u]Evelyn[/name_u] - ev-lin
[name_f]Evelyne[/name_f] - eev-lin
[name_f]Evelina[/name_f] - eh-vuh-LEEN-a.
I wouldn’t say it the other way because I find it unintuitive (doesn’t flow well), ends up sounding like Evil-eena which is unattractive, and it’s not how the majority of the world (it’s a very Slavic name) says it.
Also what @marysia said re origin from [name_f]Aveline[/name_f] (which I love).
Eh-veh-LEE-nuh
