Names by Nickname

Mari enjoyed some mid-century popularity as a nicknameish version of Mary, but now deserves a second look as a multicultural classic. Mari is the name of the Basque goddess of fertility and weather and is also, for unrelated reasons, popular in Norway. The biggest problem with the potentially-lovely Mari will be getting people to say it the way you want. While some Europeans pronounce it as Marie, that will only confuse things more. Better to make it its own individual name by pronouncing it MAH-ree. As one commenter pointed out, in Estonian the name is not a Mary variation but means "berry" – all the more reason for us to like it!

Retro short form of Marina, now dated to the era of the Hitchcock movie that made it famous. In the UK, it's one of the hottest vintage names of the moment, perhaps inspired by British singer Lily Allen, who gave it to her second daughter in 2013. It's also a character name on the hit TV show Girls.

Short form of Martin.

Marty and Martie are old-fashioned gender-neutral nickname names, boyish nicknames not heard much since the middle of the last century. They have a certain charm and may come back into style along with mother names such as Martha.

Still one of the most appealing short forms, which goes a long way toward explaining the sustained popularity of Matthew. Matt is perennially the popular guy in high school, friendly, attractive, and comfortable with a baseball. Matty or Mattie are cute for a younger boy.

Mattie, which might be a short form of Martha, Matilda, or even Madeline, ranked among the Top 100 names for girls in the 1880s and in fact, has held a place among the Top 1000 for most of U.S. naming history. It fell off the popularity charts in 2014 and makes a cute, tomboyish, if somewhat slight name option.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

May is a sweet old-fashioned name that hasn't been on the national charts in several decades, but is definitely sounding fresh and springlike. Parents are beginning to see it once more as one of the prettiest middle name options. May was as high on the list as Number 57 in the 1880s; it's now 228 on Nameberry.

Maya, which has an almost mystical image, has been steadily climbing in popularity in the US and the English-speaking world, along with a range of other countries, including France, Germany, Israel, and Brazil. It's ranked in the US Top 100 since the turn of this century, but has never risen to the top of the list, which you may consider a good thing.

Meg, perennially one of the Little Women, is a Margaret short form that manages to be neither quite in nor quite out of style. Meg is sleeker and more sophisticated than Maggie, more contemporary than Peg, more stylish than Megan, and still one of the best diminutives of Margaret.

Meg Ryan was born Margaret Mary Emily Anne.

Mellie is not Millie and it's not Nellie, though it will forever be confused with those too more familiar nicknames. It's cute, too, and while some of the names it's usually short for may be sailing into the sunset (so long, Melody!), others like Amelia are rising through the ranks and may give Mellie a new chance to shine as a cute girls' nickname. Just be prepared for endless confusion.

Merc has been introduced to the American public by the network executive character on Showtime's Episodes, and is a contemporary-sounding short form of the Roman god and planet name Mercury. Mercury, from the Latin for trade or wages, was the god of tradesmen and travelers and is the fast-moving first planet in our solar system.

She'd better be. Merry is one of the classic names for Christmas babies.

Mia is an appealingly unfussy multicultural name that has enjoyed a meteoric rise up the charts and is now firmly among the ten top girl names. Mia has surpassed its mother name Maria as the Number 1 girls' name starting with M.

Sixties-style nickname which is also the name of a small biting insect, particularly prevalent in Scotland.

Mika is a Japanese girls' name that translates easily to English. As a male name, it's a short form of Mikael, the Scandinavian and Finnish form of Michael. Both are spelled and pronounced the same.

Unlike Jake or Sam, few parents put Mike on the birth certificate.

Millie is back. It's a Top 100 name throughout much of the English-speaking world, though not yet in the US. Millicent would be an appealing long form, but many people are using Millie all by its cute self -- so many, in fact, that it returned to the Top 500 in 2015 for the first time since World War 2 and continues to climb.
