WE AGREE ON THE NAME
Brooke writes:
Our first child, a boy, will be here this summer. We are so close to agreeing on his name, and we already know what we plan to call him: Zach.
I’m writing to you because we are trying to figure out the right form of his name. We are honoring my husband’s uncle, his mom’s youngest brother, Zachary. He passed away before we met and didn’t have children of his own. He and my husband were very close and this name has always been my husband’s wish, even before we were talking about children.
Our last name sounds like Emery. So while we plan to call our son Zach, I don’t really like “Zachary Emery” together. My husband agrees. As long as we call our son Zach, the formal name doesn’t matter as much.
We have discussed these options:
- Zachariah – We both like the sound, but maybe it’s a little too different
- Zacharias – I love the way this sounds, my husband isn’t so sure but would be okay with it
- Zakai/Zachai – My husband loves this, I feel like maybe it’s a little too something? I do like that he could be Kai in the future if he didn’t want to be Zach
- Zach – This one is growing on me
- Zack – I kind of like the way this is “Jack-with-a-Z”
- Zac – Or maybe this? It seems kind of snappy and fun
The original Zachary spelled his named differently at different times. He was always Zack in school, but switched to Zach once he graduated. We don’t know why or how he felt about it, we just know he made the change.
I feel like Zach is the correct spelling for the nickname, or possibly Zac. But I feel like Zack looks better if it’s his full name.
We’re running out of time to decide and I’m a little worried that we’ll end up with his name chosen by default, just going with Zachary and not having a consistent spelling for his nickname.
Can you help us decide? I feel like there’s not any clear reason to choose one over the other.
Please read on for my response and share your thoughtful suggestions in the comments.

WORKING THROUGH THE OPTIONS
Abby replies:
Congratulations on your new son!
I think it’s smart to update an honor name slightly for a new generation. It works better with your surname, and gives your son the best of both worlds: a connection to his family, but also an identity of his own.
You’ve already spotted the key challenge, though. How do you choose which changes to make?
I think it might help to split this into two distinct choices:
- Should you choose a formal name?
- How do you choose between spellings/endings?
If you can start by answering the first question, you’ll instantly cut your options in half.
So …
Should you choose a formal name?
I’m going to start by saying yes. Why not, right? Even if you use the short form 90% of the time, it’s always there if you feel like you’d like something more formal. It’s easy to shorten a longer name. The opposite isn’t true.
Between the three choices – Zachariah, Zacharias, Zakai/Zachai – it seems like you both kind-of, sort-of, almost agree on Zachariah.
Better still? Zachary ranks in the US Top 200, but Zachariah is the next-most popular, charting in the 500s, followed by Zakai in the 600s. Zacharias and Zachai are pretty unusual, not even in the Top 1000.
That’s not always the best way to make a decision, but if you’re trying to find the most familiar version? Zachariah actually checks that box.
So I’d suggest you start with Zachariah as your front-runner and measure the other names against it.
How do you choose between spellings?
Let’s look at popularity data again.
Your instinct about Zack/Jack seems to be accurate. As an independent name, Zack is most common, followed by Zach, with Zac in last place.
But as a nickname? My guess is that the numbers aren’t that straightforward. After all, people do change their nicknames over their lifetimes – just like your late relative.
I don’t have a great reason for preferring Zach, except that the letters are right there with Zachariah and I feel like it’s the most widely-used now. 2020s parents tend to prefer nickname spellings that hew closely to the names themselves. (Case in point: Zakai is more traditionally spelled Zaccai, but the rise of Kai has pushed Zakai into wider use.)
Still, based on the numbers and your preference for Jack-with-a-Z, I think I’d nudge Zack into top place as a standalone name.
But I’ll be very curious to hear what others think on both counts.
I will say this: you’re not going to make a mistake in this narrow range of choices. They all meet both of your goals: honoring a loved one and giving your son a great start with a name all his own.




In order, my favorites are Isaac, Zakai, Zack, and Zachariah. I think Isaac and just Zack work best with their last name. Zakai is just cool. All three leave more flexibility if there might be siblings.
Also, do they have a potential nn? If they have something in mind, that could be an influence as well.
I’m in the name-them-what-you’ll-call-them camp so Zach seems pretty perfect just as-is.
If it has to be a longer name from your list, then I agree with Zachariah. But it feels redundant.
I really LOVE A’s suggestion of Isaac nn Zac. That is cool. I agree may be good to think about future siblings and where your style lies. But twisty nicknames is a fun pattern, so I’ll stick with my upvote of Isaac ‘Zac.’
Congrats and I do love a meaningful honour name.
This is my question:
what would you name another kid?
Would he have a snappy “nickname name”?
Would he have a longer, classic name with a cool nickname?
Would he have an offbeat name with a traditional-sort of nickname?
This will be a signpost for what decision to make now. If you agree on an ideal standard, your life gets so much easier!
Congratulations on your excellent son! What you’re doing is both touching and honorable.
Jenna, that’s a really good question – thanks for raising it!
What about Isaac “Zac”? Isaac “Zac” Emery sounds fantastic!
Such a good suggestion – thank you!
Zaccai or Zakkai are both real names. Itโs from the Bible. I actually like all of your options, but this one is the most distinctive sounding and it does give your son some different options.
I also agree that Zachariah nn Zach is the one to choose. I think names like Elijah and Jeremiah – with their cute nicknames – seem to be more common for kids now and Zachariah would fit right in. I donโt think Zach is hard to spell, but, if he wants to change his nickname to โZacโ or โZackโ at some point, he certainly could.
All best wishes!
I agree on Zachariah nn Zach, and even if you don’t use Zachai as the full name, you can call him Kai, because the sounds are there (and I love that option).
