Arsiah is a brand-new American coinage without a traditional source; it is best read as a modern name with "no fixed meaning" that borrows the -iah ending of Josiah, Messiah and Isaiah and gives it a fresh opening syllable. It did not appear in the national statistics with more than a handful of births before 2024, when it ranked number 9993, and it jumped to number 1809 in 2025 with 88 births.
