Meaning & vibe
Quick snapshot to help you decide if it fits your shortlist.

“Happiness” or “good fortune”.

Onni brings together two appealing meanings in one Finnish word: happiness and good fortune. As a masculine given name, it keeps the ordinary noun onni intact. “Happiness” captures the feeling of contentment; “luck” points to fortunate circumstances. Both belong to its meaning, which gives the name a cheerful, generous feel. Its four letters are spoken in two syllables, On-ni: Finnish /ˈonːi/, with stress on the first. Hold the n a little longer rather than stretching the o; that doubled consonant is a real part of the sound. The round beginning and small, clear i ending make Onni feel compact and affectionate. Its appeal is especially direct for someone who wants an uplifting word meaning without a long or ornate name.

Etymology: From the Finnish noun onni, meaning happiness, contentment or luck; the same word is used as a masculine given name.
