Rare enough to double-check

15th doesn't appear in our generated misspelling index, typically a sign the spelling maps closely to how the word sounds. It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.
This entry's etymology isn't recorded, so spelling patterns must be inferred from the word's phoneme-to-grapheme mapping rather than from a documented borrowing chain. The correct English form is 15th, spelled 1-5-T-H.
