Melinda is from the Greek meli (honey) + the Spanish -inda ("sweet, lovely") — an 18th-century English literary invention. Time 100 Most Influential People (2005). Melinda Gates (Carleton College, Duke MBA). Melinda Doolittle — American Idol Season 6 finalist. Melinda Dillon (Close Encounters, A Christmas Story).
Melinda 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 Melinda reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
