Daleyza is a modern American name with possible Arabic-Hispanic roots — from the Spanish-Arabic daleyza ("delight, joy") or from the elaboration of Dalia/Delicia. A top-500 US baby name since 2014. Daleyza Esparza — emerging Mexican-American actress. Daleyza Becerra — American beauty pageant winner.
Daleyza 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 Daleyza reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
