Liv comes from the Old Norse hlíf, meaning "protection" or "shelter." In modern Scandinavian languages, it has been folk-etymologically linked to liv, meaning "life" — so the name carries both meanings.
Liv has been popular across Scandinavia for centuries. In the U.S. it is rising fast — short, sharp, with one of the most direct possible meanings.
Liv does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Liv reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
