Lujain (لجين) is the Arabic word for "silver" — specifically pure, lustrous silver. A poetic Arabic feminine name evoking moonlight and the precious metal.
Used widely across the Arab world.
Lujain 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 Lujain reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
