About the name
Isaiah is Hebrew Yeshayahu, salvation of the Lord — the same yasha root behind Joshua, Hosea and Yeshua. The prophet's book supplies more of the language of Handel's Messiah than any other, which is why phrases from it are familiar to people who have never opened it.
It was rare in America until the 1970s and has been inside the top 100 since the 1990s, now at number 57. The -iah ending put it in the same wave as Josiah, Jeremiah and Nehemiah.
Zay is the short form that sounds nothing like the name. Three syllables want one or two (Isaiah Cole, Isaiah Reed). On our vibe map it is Heirloom with Modern Minimalist edges.
