Jasiah
Meaning
modern phonetic variant of Josiah, Hebrew for 'God supports'
The story
Jasiah is the Josiah sound in a modern phonetic spelling, God supports in the old Hebrew, and the anchor is one of the era's quiet giants: Josiah, the boy-king who found the lost book of the law, counts about 149,200 with its own story here. Jasiah's record is young and steep: about 130 in the 1990s, 1,900 in the 2000s, cresting at 4,500 in the 2010s, with 3,700 so far this decade, nearly all boys, about 9,600 to 650. The J-spelling keeps the sound and simplifies the road to it, the same legibility instinct Johnathan follows in our records; the support in the root passes through untouched. An old king, a young spelling, and a record climbing the way the family's records climb: steadily, and without a spike.
