Sifan is from the Amharic sīfān — "completeness" or "perfection" — an Ethiopian female name. Praying as a devout Muslim during competition — including drinking water during the fasting month of Ramadan in 2023 London Marathon — has brought broader attention to the cultural-religious dimensions of elite running.
Sifan 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 Sifan reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
