Cariad is the Welsh word for "love" or "beloved" — used both as a term of endearment and a feminine name. Welsh speakers traditionally call loved ones cariad.
Cariad is rare but distinctive in Welsh communities.
Cariad 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 Cariad reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
