About the name
Aino means the only one, and is one of the few names that can be dated precisely: Elias Lönnrot coined it for the *Kalevala* in 1835, building it from the Finnish ainoa. The character drowns herself rather than marry the old man who has won her, and becomes a fish.
It is now thoroughly ordinary in Finland, which is what happens to invented names that are built correctly — nothing about it sounds constructed to a Finnish ear.
Two syllables, said EYE-no. Both vowels are pure and the stress is on the first, as it is in every Finnish word. On our vibe map it is Mythological with Nature-Inspired colour.
