A short, bright name which originates as a short form of names including Tiana, and Tatiana. Not as popular as Mia – a plus if you're seeking a short and pretty but less common name.

Cute and unusual as a nickname, but lacking the legs to stand on its own.

Actress Tilda Swinton injected this dated nickname name with some modern charm.

Tony, as in classy. Or To-nyyy, as yelled out a tenement window.
