Very sweet; completely diferent than the masculin form. The "a" gives it a lighter, softer aura.
This is a name which sounds good on a little one and can also be taken seriously on a grown woman.
And I personally like the "K" because it ads flavor and looks more original without changing the pronunciation.
PS: I have liked the name
Dominic since The Lord of the Rings trilogy came out and that was the name of one of the actors playing a hobbit,
Merry the prankster cousin.
