Lumi is the Finnish word for "snow" and is also used as a short form of names built on the Latin lumen, "light", such as the Romanian Luminita. Its crisp, two-syllable sound fits the recent fashion for short, bright girls' names like Luna and Nova. Lumi was very rare in the United States at number 9281 in 2015, rose to number 2135 in 2022 and reaches number 1953 in 2025, its best rank so far.
