Malachi
Masculine · “my messenger”
Malachi is overwhelmingly a boys’ name — 65,758 boys against 290 girls since 1880.
Malachi closes the Hebrew Bible: the last book of the Old Testament carries this name, and it has been read aloud in synagogues and churches for well over two thousand years. In English it keeps three unhurried syllables and ends on that open -kye, the same long sound that lands at the end of Eli and Zachariah. Its Irish cousin Malachy took the same letters down an entirely different road.

Where it comes from
From Mal'akhi to Malachi
The story of Malachi
The name is Hebrew, and it enters the record as the title of the final book of the Hebrew Bible, written after the return from exile in Babylon. Greek translators rendered it Malachias, Latin kept that form, and from Latin it spread into the liturgical vocabulary of Western Europe — hence Spanish Malaquías and Italian Malachia. In Ireland something more unusual happened: the sound of Malachy was adopted as the English stand-in for the old Gaelic names Máel Máedóc and Máel Sechnaill, so that the twelfth-century archbishop of Armagh, Máel Máedóc Ua Morgair, is known in English as Saint Malachy. English-speaking parents drawing on Old Testament names took up the biblical spelling, Malachi, which is the form now standard in the United States.
Meaning
my messenger
From Hebrew mal'akhi, built on mal'akh, "messenger" — the same word used for angels in Hebrew scripture, which is why "my angel" also appears as a rendering. Biblical scholars have long discussed whether the word at the head of the book was a personal name or simply a description of the prophet; either way, the meaning of the word itself is not in doubt.

Pronouncing Malachi
MAL-uh-kye
Stress on the first syllable, and the last syllable rhymes with "eye" — this is the settled American pronunciation of the biblical spelling. The Irish form Malachy is said MAL-uh-kee, which is where most of the confusion between the two comes from.

The Karl test
Every popular name lives one long story — a climb, a peak, a slow settling back. Malachi's later chapters haven't been written yet, so we borrowed them: Karl climbed just as high around 1960, and its whole arc is on record. Line the two peaks up, and Karl's path sketches the road Malachi is walking now.

The trade-off
- A spelling fixed in print for centuries by the Bible, so most people have seen it written before they hear it.
- Two established short forms that need no explanation: Mal, and Kai, which is a familiar standalone name.
- Recognizable in Spanish, Portuguese, Italian and Irish versions, which travels well in a bilingual family.
- Familiar to nearly everyone yet rarely duplicated — a Malachi is usually the only one in his year.
- An unbroken written record from post-exilic Hebrew scripture to today, with no gaps to explain.
- The -kye ending will be tested. People who know the Irish Malachy, or who have only read the name, often try MAL-uh-kee first. Most families find one gentle correction settles it.
- Malakai, Malaki and Malachai all circulate, so he may need to spell it out on forms even though his version is the biblical one.
- The association with the closing book of the Old Testament is strong and immediate. For some families that is the whole appeal; if you would rather the name not read as a statement of faith, it is worth knowing that is the first thing many listeners hear.
