As the common short form of Zachary or, more unusually, Zachariah, Zack is less intuitive than Zach or Zac in terms of spelling but clearer in terms of pronunciations. Maybe because it rhymes with Jack and Mack, it also feels more complete as a name. Some people also use Zack and brothers as a short form of Isaac.

The name Jo still evokes the spunky image of the character in Louisa May Alcott's Little Women. Its literary status makes Jo one of the OG boyish nicknames for girls, ala Frankie, Billie, and Stevie. If you like that form, you can lengthen it to Joey.

Many variations of Jessica, including Jessie and Jessa, are used on their own, but Jess is an exception, given to only a handful of baby girls last year. But Jess is certainly the name that many Jessicas are called.

At the height of the Jennifer craze, many parents were cutting straight to the nickname and putting Jenny on the birth certificate. But now that Jennifer is the mom rather than the daughter, Jenny, which has been somewhat replaced by Jenna, has faded as well.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.

Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.
 Gus was chosen for their sons by Dixie Chick Emily Robison and actress Julie Bowen. In T.S. Eliot's Old Possum's Book of Practical Cats (and in the stage musical), the full name of Gus the Theatre Cat is Asparagus.
