What Does Isaiah Mean?
The name Isaiah is a theophoric name (a name that embeds the name of a deity) of Hebrew origin. It is derived from the Hebrew name Yesha’yahu. To fully understand the depth of the meaning, we must break it down into its two component parts:
- Yesha: This root word means “to save” or “salvation.”
- Yahu: This is a shortened form of Yahweh, the Hebrew name for God.
When combined, Isaiah translates to “Yahweh is salvation” or “God Saves.” It shares the exact same etymological components as the name Joshua and Jesus, just arranged in a different order. It acts as a statement of faith, suggesting that the bearer is under the protection or deliverance of the divine.
Where Does the Name Isaiah Come From?
The name originates directly from the Old Testament of the Bible. Isaiah is one of the most significant figures in Judeo-Christian history. He was a Major Prophet who lived in the Kingdom of Judah during the 8th century BC (1).
He is often called the “Prince of Prophets” because the Book of Isaiah is celebrated for its rich poetry and complex theology. Historically, the name was largely restricted to Jewish communities until the Protestant Reformation, when Puritans began using an English name translation of Biblical figures for their children.
How Popular is the Name Isaiah?
Isaiah is what we call a “Modern Classic.” While it has ancient roots, it wasn’t a top-tier name in the US until recently.
In the mid-20th century, Isaiah was considered relatively obscure, often ranking near the bottom of the Top 1000. That changed dramatically in the 1990s. As parents began looking for alternatives to the omnipresent “Michael” and “Christopher,” Isaiah skyrocketed.
It broke into the Top 100 in 1996 and has stayed there ever since. It peaked around number 40 in 2006. In 2025, Isaiah remains a comfortable favorite; it is popular enough to be recognized instantly but has cooled off just enough that your child likely won’t be one of three Isaiahs in his kindergarten class.
How Do I Pronounce Isaiah?
The standard American English pronunciation is eye-ZAY-uh.
The emphasis falls firmly on the second syllable. A common point of confusion is the “S” sound. In English, the “S” takes on a “Z” sound.
- Correct: eye-ZAY-uh
- Incorrect: eye-SAY-uh (unless using a specific cultural variation)
Is Isaiah a Boy or Girl Name?
Isaiah is traditionally a Hebrew boy’s name. According to Social Security Administration data, over 99% of babies named Isaiah are male.
However, modern naming conventions are increasingly fluid. Because the name ends in “ah” (similar to Sarah, Hannah, or Delilah), some parents see potential for it as a girl’s name. It is similar to how “Noah” has seen usage for girls recently. Despite this, if you name a girl Isaiah, be prepared for her to be mistaken for a boy on paper.
