Suad (سعاد) is the Arabic word for "happiness" or "good fortune" — from the same root as Saudi.
Suad Hosny (1943-2001) was the legendary Egyptian actress known as "Cinderella of the Arab Cinema."
Suad 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 Suad reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
