Alaina is the feminine form of Alan — from the Old French Alain, possibly from the Celtic alun, meaning "beautiful" or "fair." The name is also linked to a Germanic form meaning "precious."
Alaina has been rising steadily in the U.S. since 2003. Today it sits in the U.S. top 200. Three soft syllables, soft sounds, gentle meaning.
Alaina 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 Alaina reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
