Questions about this tool
Is the pair checker a compatibility score?
No. It lists observations: each spelling’s published 2025 rank and count, the letter lengths and their sum, vowel groups in the spelling, whether the initials match, and whether each larger category rose, fell, or held steady from 2021 to 2025.
What is a vowel group?
A run of the letters a, e, i, o, u, or y. It is a count of those letters. It is not a pronunciation and not a dictionary syllable count.
When is the direction incomplete?
When either name has no published 2021 count in the recorded-sex category with the larger 2025 count. A missing count is not treated as zero, so the checker does not call that name rising or falling.
