Arlo
| Origin | Genuinely uncertain. The strongest thread leads to Arlo Hill, Edmund Spenser's anglicisation of the Irish valley name Aherlow (Irish Eatharlach), in the Mutabilitie Cantos of The Faerie Queene, published in 1609 after his death |
|---|---|
| Meaning | Not established. Two glosses circulate: "fortified hill", got by treating Arlo as a form of Harlow (Old English here, army, + hlaw, hill), and "barberry tree", offered as Spanish. Neither is supported; treat both as folk etymology |
| Pronunciation | AR-loh (two syllables, stress on the first) |
| Popularity | Outside the current U.S. top 100; far commoner in Britain and Australia than in America, where it is still an unusual choice |
| Variants | Arlow. Harlow looks like a variant but is a separate name with a separate history |
| Nicknames | Ar, Lo |
| Famous bearer | Arlo Guthrie, born 1947, the American folk singer behind "Alice's Restaurant" and the son of Woody Guthrie |
History & meaning
Most names come with an etymology attached. Arlo does not, and the honest version of its story is a shrug held for a long time. The earliest solid appearance of the word is geographic: Edmund Spenser, writing at his estate at Kilcolman in County Cork, gave the name Arlo Hill to a peak in the Galtee mountains nearby, anglicising the Irish valley name Aherlow. That passage sits in the Mutabilitie Cantos, printed in 1609, a decade after Spenser died. How the word travelled from a poet's map to a christening register is not documented.
What the reference books offer instead are guesses dressed as facts. One drags Arlo toward Harlow and hands it "fortified hill" from Old English here and hlaw; another calls it Spanish for the barberry, a claim with nothing behind it. Neither survives contact with evidence. What is documented is the name's American career, which begins with Arlo Guthrie, born in Brooklyn in 1947 and named Arlo Davy by Woody and Marjorie Guthrie. Britain and Australia took the name up in earnest in the 2010s, and Pixar put an Arlo on cinema screens as the young dinosaur in The Good Dinosaur in 2015.
Why parents choose it
Arlo lands in the same warm, unbuttoned register as Milo, Otto and Theo: two syllables, an open O at the end, nothing to spell out over the phone. The absence of a meaning turns out to be part of the appeal. A child called Arlo inherits a sound and a folk singer, and nothing else is being asked of him.
Middle names for Arlo
The O ending swallows vowels, so start the middle name with a consonant and give it some length: Arlo Bennett, Arlo James, Arlo Nathaniel, Arlo Hugh. The middle names guide explains why the vowel collision matters more than it looks.
Famous Arlos
Arlo Guthrie is the anchor, still touring decades after the eighteen-minute talking blues that made his name. Arlo White, born 1973, is the English commentator who called Premier League and MLS matches for American audiences through the 2010s. The British musician and Mercury Prize winner Arlo Parks uses the name as a stage name; she was born Anaïs Oluwatoyin Estelle Marinho, which is worth knowing before assuming the name's gender has shifted.
Consider instead
For the same short O-ending shape with a clearer pedigree, Theo is Greek and unimpeachable. Bram keeps the offbeat, slightly literary feel in one syllable. Fox matches the modern, meaning-light appeal and pushes it further. There are more on the A names page.
