Hayat (حياة) is the Arabic word for "life" — used widely across Arabic and Amharic naming traditions.
Hayat is widely used in the Arab world and Ethiopia.
Hayat 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 Hayat reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
