Tilda is the German-Scandinavian short form of Matilda — from the Old High German Mahthildis, maht (might) + hild (battle). BAFTA Fellowship (2020). "Tilda" Lindstrom is a top Swedish rice brand. Saint Matilda of Quedlinburg — 10th-century German queen.
Subject of countless avant-garde cinema profiles.
Tilda 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 Tilda reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
