You’re staring at the board. The tiles are clunky, the score is tight, and you have a "B" and an "O" left over while your opponent is smugly waiting for you to pass. It’s the classic Scrabble dilemma. You want to drop those two letters down and claim your points, but a voice in the back of your head is whispering that it’s too simple. It feels like a "cheat" word. You might even be worried about getting challenged and losing your turn.
So, let's settle the debate right now: is bo a scrabble word?

Yes. It absolutely is.
But there is a catch—isn't there always? Whether you can use it depends entirely on which side of the Atlantic you’re playing on or which specific dictionary your group has agreed to use. If you are playing in a standard North American tournament or a casual living room game using the Official Scrabble Players Dictionary (OSPD), you are golden. It’s a legal, two-letter powerhouse.
The Dictionary Divide: Why "Bo" Isn't Always a Lock
In the world of competitive word games, the dictionary is the law. If you're using the Merriam-Webster Scrabble dictionary (the standard for the US, Canada, and Thailand), bo is a valid word. It’s been in there for years. It’s a staple for high-level players who need to hook a letter onto a "B" or an "O" to open up a triple-word score.
However, if you're playing by SOWPODS rules—which is the international standard used in the UK and most other countries—things get a little murky. The Collins Scrabble Words list is the "bible" for international play. For a long time, bo was a point of contention. While many two-letter words are universal, some are regional. Always check the "house rules" before you lay it down, especially if you’re playing against someone who grew up playing with the British dictionary.
It’s a slangy word, sure. But Scrabble loves slang as long as it’s documented.
What Does "Bo" Even Mean?
You can't just throw random sounds onto the board and hope they stick. Most people think "bo" is just the first half of "boyfriend" or a shortened version of "brother," and while that's how we use it in text messages, that’s not why it’s in the dictionary.
In the Scrabble world, bo is defined as a slang term for a fellow, a guy, or a pal. It’s essentially a variation of "boy" or "buddy." It has roots in American English, often associated with a sort of hobo-adjacent vernacular from the early 20th century. Think of it as the precursor to "bro."
There's also the martial arts angle. A "bo" is a long staff used in Japanese martial arts (the bō staff). While the dictionary primarily cites the "fellow" definition, the existence of the physical object gives it extra linguistic weight.
The Strategic Power of Two-Letter Words
Casual players often overlook the two-letter list. They’re hunting for "QUARTZ" or "ZOMBIES," ignoring the fact that the game is often won in the trenches with tiny words. Is bo a scrabble word that can actually win you the game? Honestly, yes.
Imagine you have an "O" and your opponent has left a "B" dangling near a Triple Letter score. By playing "BO" across that spot, you aren't just getting the face value of the letters. You’re potentially playing "BO" vertically and another word horizontally, doubling or tripling the points for both letters.
Two-letter words are the "connectors." They are the glue that allows you to play parallel to other words. Without words like bo, ba, bi, and ab, the board would become stagnant very quickly. If you have a "B" and you can't find a place for "BE" or "BY," "BO" is your emergency exit.
Don't Confuse Bo With Its Cousins
Scrabble is a game of precision. One letter off and you've lost your turn.
- BA: Valid. It’s an Egyptian soul concept.
- BI: Valid. Short for bisexual.
- BO: Valid. Our hero of the hour.
- BU: NOT valid. Don't try it. You'll get challenged.
- BY: Valid. A preposition.
It’s funny how the brain works under pressure. You might think "Bu" sounds like a word, but in the Official Scrabble Players Dictionary, it’s a no-go. Stick to bo.
Why Your Friends Might Challenge You
The reason bo causes so many arguments at the dinner table is that it feels "too informal." Many people grew up playing Scrabble with the "no slang" rule. But the modern Scrabble dictionary has evolved. It’s not just about "Queen's English" anymore. It’s about usage.
If your Aunt Martha scoffs and says, "That's not a real word, that's just something people say in movies," you can politely point out that the OSPD6 and OSPD7 (the latest editions) explicitly include it.
The game has changed. We have "OK," "EW," and "ZA" (short for pizza) now. Compared to those, bo feels almost ancient and dignified.
The "Bo" Variations
If you have more letters to work with, bo is a fantastic foundation. You can extend it into:
- BOAS: Plural of the snake.
- BOAR: The wild pig.
- BORE: To be dull or to drill.
- BOHO: Short for bohemian (also a valid Scrabble word!).
- BOBO: A bourgeois bohemian (yes, really, it’s in there).
Real-World Tournament Context
In the 2014 National Scrabble Championship, a dispute over a two-letter word nearly derailed a mid-tier match. It wasn't bo, but it highlights the tension. Players at that level memorize all 107 (or 120+ depending on the year) two-letter words. They don't even think about the meaning. To a pro, bo isn't a "fellow" or a "staff"—it's a 4-point play that keeps the rack moving.
If you want to play like a pro, stop worrying about whether the word sounds "right." If it's in the book, it's a weapon. Use it.
How to Memorize the "B" Two-Letter Words
Instead of trying to remember the whole dictionary, just memorize the "B" cluster. It's short.
- BA
- BE
- BI
- BO
- BY
That's it. Notice there is no "BU." If you remember "BA-BE-BI-BO-BY," you’re essentially a Scrabble shark. You can hook these onto almost any vowel-heavy board.
Final Verdict on the Bo Controversy
The next time someone asks is bo a scrabble word, you can confidently say yes, provided you are using the North American rules. It’s a 4-point word (3 for the B, 1 for the O) that functions as a vital bridge for more complex plays. It’s been officially recognized for decades, and its presence in the dictionary is a testament to how the English language—and the games we play with it—constantly adapts to how people actually speak.
Actionable Next Steps for Your Next Game:
- Check the Dictionary First: Before the first tile is drawn, confirm if you are using the Official Scrabble Players Dictionary (Merriam-Webster) or the Collins Scrabble Words (SOWPODS). This prevents mid-game "bo-based" blowups.
- Print a Cheat Sheet: Keep a list of all legal two-letter words nearby. Most casual groups allow this as it speeds up play and prevents constant debating.
- Look for "Hooks": Don't just play bo in an empty space. Look for an existing "S" on the board to make "BOS" or an "A" to make "BOA."
- Practice Your Defense: If someone tries to play "BU," challenge it immediately. Knowing what isn't a word is just as important as knowing what is.
Don't let a small word intimidate you. Lay down the B, drop the O, and take your points. It’s perfectly legal, totally smart, and honestly, a bit of a power move.
