The baby name Io

Jupiter's moon Io (NASA)
Io (in front of Jupiter)

Several days ago, NASA’s Astronomy Picture of the Day was the impressive “Io: Moon Over Jupiter,” which was taken by the Cassini spacecraft.

Jupiter’s moon Io (pronounced IE-oh) was discovered by Galileo in 1610. He named it for the mythological character Io — a nymph who was seduced by Zeus, then turned into a cow.*

The baby name Io doesn’t have a known meaning, and it’s rarely used in the U.S.:

  • 2010: 6 baby girls named Io
  • 2009: 8 baby girls named Io
  • 2008: 5 baby girls named Io
  • 2007: 5 baby girls named Io
  • 2006: 5 baby girls named Io

Nevertheless, I’ve always found it intriguing. There aren’t many two-letter girl names out there, and this is the only one I know of from Greek myth.

Do you like the name Io? Would you give it to your baby girl?

*The name of the Bosphorus, which comes from ancient Greek and means “cow passage,” commemorates Io-the-cow’s crossing of the strait.

P.S. Io backwards is Oi. :)

Baby names typed by the right hand: Better?

computer keyboard

Years ago, I came up with a list of one-handed baby names — that is, names that are typed with either the left hand or the right hand on a QWERTY keyboard.

Turns out there may be a slight advantage to right-hand names.

According to a study published recently in Psychonomic Bulletin and Review, “the QWERTY keyboard may gradually attach more positive meanings to words with more letters located on the right side of the layout (everything to the right of T, G and B).”

Why?

It has to do with fluency.

We tend to like simplicity over complexity, and the harder-to-type letter pairs are on a QWERTY keyboard’s left side — these two facts together may lead people to prefer words (and names) that are typed on the right.

Which names are typed by the right hand only? My original list:

  • Holly
  • Io
  • Jill, Jim, Jimi, Jimmy, Jin, Jo, John, Johnny, Jon, Joni, Joy, Juho, Juli, Julio, Jun, Juno
  • Kiki, Kim, Kimi, Kimiko, Kimmy, Kimo, Kip, Kiyoko, Kojo, Kollin, Kumiko, Kyou
  • Lili, Lilly, Lilou, Lily, Lin, Lino, Loni, Lonny, Lou, Lulu, Lyn, Lynn
  • Miki, Mikki, Mikko, Milly, Milo, Mimi, Min, Minh, Miyu, Molly, Momoko
  • Nik, Nikhil, Niki, Nikki, Niko, Nikol, Nikon, Nuno
  • Olli, Olujimi, Om
  • Phil, Philip, Phillip, Pio, Polly, Poppy
  • Yoko, Yuko, Yumi, Yumiko

Can you think of any others?

Baby names spelled with the names of letters: Ivy (IV), Casey (KC), Ellie (LE)

A reader named Becky recently emailed me with a rather cool request:

We’re looking for a girl name that has an actual spelling and letter combinations to represent the word. For example Evie (EV) and Katie (KT). Any suggestions would be great!

Here’s a long list of (mostly female) names that can be spelled with the names of letters. Some of the letter strings don’t quite replicate the pronunciation of the corresponding name, but, even if they don’t match perfectly, they do come pretty close.

Can you guys think of any others? Let me know and I’ll add them!

Update, 2015: Here’s a baby girl named Elloebee, a phonetic spelling of the acronym LOB (“legion of boom”).

Update, Feb. 2025: Just spotted the name Effely (FLE) in an article about Cambridgeshire baby names.

Update, Apr. 2025: Here’s a college basketball player named Azzi Fudd, first name pronounced like the letters A and Z.

Update, Jul. 2025: Here’s a 19th-century baby girl from Norfolk, England, named Emdiella (MDLR).
