You're staring at your rack. It’s the final turn of a high-stakes Scrabble match, or maybe you're deep into a late-night Wordle spin-off that's getting way too competitive for 2:00 AM. You have the Z. It’s the highest-value tile in the bag, worth a whopping 10 points, but your board is cluttered and there isn’t a single open "OO" for "ZOO" or "EN" for "ZEN." You're basically stuck. Or are you? Honestly, most casual players think they need a vowel-heavy long word to dump the Z, but the real experts—the folks who memorize the Official Scrabble Players Dictionary (OSPD)—know that two letter words starting with z are the ultimate "get out of jail free" cards. They are tiny. They are weird. And they are absolutely legal.
The Short List: ZA and ZE Explained
If you’re looking for a massive list, I’ve got some bad news: there are only two. Just two. In the standard American English lexicon used by the National Scrabble Association (NASPA), your options for two letter words starting with z are "ZA" and "ZE." That’s it. But don't let the quantity fool you. These two words change the math of the game entirely.
Let's Talk About ZA
You’ve heard it before. Maybe in a 90s teen movie or at a college dorm at 3:00 AM. ZA is a slang shortening of "pizza." For years, it was a point of contention among linguistic purists who thought slang had no place in serious board games. However, the Merriam-Webster editors eventually leaned into the reality of how people actually speak. It was officially added to the OSPD4 in 2005.
Why is it so good? Because "A" is the most common vowel. You can almost always find an "A" floating around on the board. If you can hook your Z onto an existing A to form ZA, and that Z happens to land on a Triple Letter Score, you’ve just bagged 31 points with a two-letter word. It’s kind of ridiculous when you think about it. You’re essentially scoring more than someone who painstakingly crafted a seven-letter word like "TRAINED."
The Rise of ZE
Then there’s ZE. This one is a bit more modern in its mainstream acceptance, though it has roots in older linguistic attempts at gender neutrality. Specifically, ZE is a gender-neutral pronoun. While it feels like a 21st-century addition, variations of it have been kicked around by grammarians for decades. It finally made the cut for competitive play because its usage became frequent enough in published literature and reputable journalism to meet the dictionary's "sustainable use" criteria.

From a strategy perspective, ZE is a lifesaver. If you have an "E" on the board—and let's be real, there are always Es on the board—you have a landing spot for your Z. No more "fishing" for a better hand. You play the ZE, take your points, and move on.
Why These Words Actually Matter for Your Brain
It isn't just about winning a game of Words With Friends against your aunt. Understanding the constraints of two letter words starting with z is a lesson in linguistic economy. We often think of language as this vast, infinite ocean, but in the world of high-value scoring, it’s a game of narrow corridors.
Stefan Fatsis, the author of Word Freak, spent years embedded with the world's best Scrabble players. One thing he noted was how these experts don't view words as meanings; they view them as "string units." To a pro, ZA isn't a slice of pepperoni pizza. It is a 10-point consonant paired with a 1-point vowel. It’s a tool. When you start seeing words this way, your spatial awareness on the board improves. You stop looking for "words you know" and start looking for "mathematical opportunities."
The International Twist: Why Your Friends Might Argue
Here is where things get messy. If you are playing in the UK or using the Collins Scrabble Words (CSW) list—often referred to as SOWPODS—the rules change. In the international scene, they have a different relationship with the Z.

While ZA and ZE are generally accepted, you might run into people trying to play ZO. In some specialized dictionaries or older editions, ZO (a cross between a yak and a cow) was a debated entry. However, for the vast majority of competitive play in North America, ZO is a big fat zero. If you try to play it and get challenged, you'll lose your turn. It’s a classic trap. Always clarify which dictionary you’re using before the first tile is drawn. Honestly, there’s nothing worse than a friendship-ending argument over whether a Himalayan bovid belongs on a game board in Ohio.
Master the "Parallel Play"
The real power of two letter words starting with z comes through parallel playing. This is the tactic where you lay a word alongside another word so that every touching letter forms a new, tiny word.
Imagine the word "AT" is already on the board horizontally. If you place "ZA" vertically so that the Z sits right above the A, you aren't just scoring for ZA. You're scoring for the Z twice because it’s part of two different words simultaneously. This is how players turn a 10-point tile into a 40 or 50-point turn without ever breaking a sweat.
- Look for floating vowels: A, E, and sometimes O (if you're playing by international rules).
- Check the corners: High-value tiles are best used near "Double Word" or "Triple Word" squares.
- Don't hold the Z too long: A common mistake is waiting for the "perfect" long word. In the time you spend waiting for "ZIGGURAT," you could have played ZA three times and won the game.
Common Misconceptions and Fake Words
People try to sneak things past their opponents all the time. I've seen "ZI," "ZO," and even "ZU" attempted in casual games. Let's be clear: unless you've agreed on a "house rules" dictionary, these are not valid.

- ZI: Not a word. You might be thinking of "chi" or "pi," but ZI doesn't exist in the OSPD.
- ZU: Often mistaken for "ZOO." It’s not a thing.
- ZY: People think this is a shortcut for "zyzzyva" or "zygote." It isn't.
Stick to the basics. Memorize ZA and ZE. They are your two best friends in the world of gaming.
Actionable Strategy for Your Next Match
If you want to move from a casual player to someone people are actually afraid to play against, you need to internalize these two words until they are second nature.
- Step 1: Next time you practice, force yourself to use the Z within the first three turns. Don't let it clog up your rack.
- Step 2: Scan the board specifically for "A" and "E" tiles that are adjacent to "Double Letter" or "Triple Letter" bonus squares.
- Step 3: Practice "hooking." See if you can add a Z to an existing word. For example, if "EAT" is on the board, can you put a Z in front of it to make "ZEAT"? No, because that's not a word. But you could put a Z above the E to make ZE and something else.
The goal isn't just to know the words; it's to see the board as a grid of potential connections. The Z is a lightning bolt. If you know where to ground it, you'll dominate.
Next time you draw that 10-point tile, don't panic. Don't look for a 6-letter masterpiece. Just look for an A or an E. Drop that ZA or ZE, collect your points, and watch your opponent's face as they realize they're playing against a pro.
