You’re staring at a rack full of vowels. It’s frustrating. You’ve got an "I" and maybe a "U" or an "O," and the board is so crowded you can’t find a spot for a five-letter word to save your life. This is exactly where most casual players lose the game. They hunt for the big, flashy plays while ignoring the microscopic glue that holds a high-scoring board together. Honestly, 2 letter words starting with i are the secret weapon of tournament players, not because they score fifty points on their own, but because they allow for parallel plays that rack up score multipliers like crazy.
If you aren't using these, you're basically playing with one hand tied behind your back.
Most people know "is" and "it." Those are easy. But what about the ones that sound like typos? Words like "id," "if," "in," "is," and "it" are the bread and butter, but when you get into the Scrabble dictionary (specifically the Official Scrabble Players Dictionary or the NASC-approved word lists), things get a little weirder. You have "id," "if," "in," "is," and "it," but also "io."

Let's break down why these tiny fragments matter so much and how to actually use them without looking like you're just making stuff up.
The Words That Actually Exist (And Why)
In the world of competitive word games, "in" is a powerhouse. It’s a preposition, sure, but it’s also a noun in some contexts (like having an "in" with someone). Then there’s "if." Simple. Common. But in a game of Scrabble or Words With Friends, "if" is a lifesaver when you have an 'F' and nowhere to put it.
"Is" and "it" are your workhorses. You use them to hook onto existing words. If someone plays "CAT," you can play "IT" vertically off the 'T' to create "T-I-T" and "I-T" simultaneously. That’s a "hook" play. It doubles your efficiency.
Then we get to "id." It’s a psychoanalytic term. Freud loved it. Scrabble players love it more. If you have a 'D' and an 'I', and the board is tight, "id" saves your turn.
Wait, what about "io"?
This is where people start arguing. "Io" is technically a moon of Jupiter, but in many word game lexicons, it’s accepted as an exclamation or a cry of joy. However, you have to be careful. In the standard Merriam-Webster Scrabble dictionary, io is often excluded, whereas in international SOWPODS play, it might be fair game. Always check your "house rules" or which dictionary app you’re using before you try to slide "io" past a grumpy opponent.
Why Small Words Win Big Games
It’s about the "parallel play."
Imagine there is a word like "TRAIN" on the board. If you play "IS" directly underneath "TR," you aren't just getting points for "IS." You are getting points for "I" connected to "T" (creating "IT") and "S" connected to "R" (creating "SR"—wait, "SR" isn't a word). Okay, bad example. Let’s try "IS" under "AN." Now you’ve made "AI" and "NS." "AI" is a word (a three-toed sloth, or artificial intelligence in some modern lists), and "NS" is not.

See? Even experts mess up the overlaps.
The trick with 2 letter words starting with i is knowing which ones allow for these stacks. "In" is the king of the stack. If you put "IN" under "TO," you get "TI" and "ON." Both are legal. You just tripled your points for a two-letter move. It’s sort of like a cheat code that’s perfectly legal.
The "ID" Misconception
People think "ID" is just an abbreviation for "Identification." If it were just an abbreviation, it wouldn't be legal in Scrabble. Abbreviations are banned. "Id" is legal because it’s a distinct noun referring to the part of the psyche. This is a nuance that separates the casual Friday night players from the people who travel for tournaments.
The "IF" Strategy
"If" is tricky because of the 'F.' The letter 'F' is worth 4 points. In the early game, you want to save that 'F' for a "Triple Letter" or "Double Word" score. But in the end game, when the board is a mess of tangled letters, "if" is often the only way to get that 'F' out of your rack. Holding onto high-point letters at the end of the game is a death sentence because their value gets subtracted from your score if your opponent finishes first.
Modern Language vs. Official Lists
Language changes. Google Discover is full of "Gen Z slang" articles, but Scrabble is slow.
You might use "im" as a shorthand for "I'm" in a text. Don't try that on the board. Apostrophes don't exist in Scrabble. "Im" is not a word. Neither is "ir." Even though we use "ir-" as a prefix for "irregular" or "irrelevant," prefixes alone aren't words.
This is a huge trap for people who read a lot but don't play competitive games. Just because you see it in a book or a text message doesn't mean the North American Scrabble Players Association (NASPA) cares. They are traditionalists. Sorta.
Actually, they did add "OK" recently, which felt like a tectonic shift in the word game world. But for "I" words, the list remains short and sweet:
- Id: The primitive part of the mind.
- If: A condition.
- In: To go inside; a position of influence.
- Is: Form of "to be."
- It: A pronoun for a thing.
Beyond the Board: Why These Words Matter in Tech
In the world of technology and coding, these tiny words are actually everywhere. "If" is the foundation of all logic.if (x > y) { do something }
Without that two-letter word, we don't have software. We don't have the internet.
In SEO, "in" and "is" are "stop words." Search engines used to ignore them to save processing power. Now, thanks to natural language processing, Google actually looks at them to understand intent. "Pizza in New York" is a very different search than "Pizza New York." The tiny word "in" provides the geographical context that triggers the local map pack.
Nuance and Complexity: The Controversy of "IS"
Is "is" always a verb?
Actually, in some linguistic circles, the way we use these tiny words defines our entire worldview. E-Prime (English-Prime) is a version of English that forbids all forms of the verb "to be" (is, am, are, was, were). The idea is that saying "The movie is good" is a false statement because it implies "goodness" is an inherent property of the movie. Instead, E-Prime users say "I liked the movie."
It forces accuracy.
While you won't get extra points for "is" by explaining Aristotelian logic to your Scrabble opponent, it's a fun way to kill time while they spend ten minutes trying to find a seven-letter word that doesn't exist.
Tips for Memorizing and Using These Words
You don't need a PhD to remember five words. You just need a strategy.
- The "Vowel Dump": If your rack is "I, I, I, A, E, O, U," you are in trouble. You need to shed those vowels. Playing "IN," "IS," and "IT" in quick succession—even if the points are low—refreshes your rack and gives you a chance at a "Bingo" (using all seven tiles) on the next turn.
- Parallel Scoring: Look for a word like "BASKET." If you can play "IN" parallel to the "BA," you score for "IN," "BI," and "AN." That’s three words for the price of two letters.
- Defensive Play: Sometimes you play a two-letter word just to block your opponent. If there is a "Triple Word Score" hanging open, and you can’t reach it, you might play "ID" right next to it so your opponent can't land a massive word there.
Actionable Insights for Your Next Game
Stop looking for the long words. Honestly. If you want to win, you have to embrace the tiny ones.
First, go through your favorite word game app and try these words. See which ones the dictionary accepts. If you're playing a physical board game, agree on a dictionary before the first tile is placed. Using a 2024 dictionary vs. a 1990 dictionary will change your strategy because the "acceptable" list has grown.
Second, practice "stacking." Take a sheet of graph paper. Write a five-letter word. Now, try to fit 2 letter words starting with i directly above or below it so that every new vertical pair created is also a valid word. It’s harder than it looks, but once you see the patterns, you'll start seeing them on the board every time.
Third, don't be afraid of "ID." People think it's an abbreviation. It isn't. It's a gold mine.
Next time you’re stuck with an "I" and a "D," don't swap your tiles and lose a turn. Just play "ID" on a Double Letter score and keep the momentum going. Momentum wins games. Big words just look good on the scoreboard for a minute, but the small ones win the season.
Start by memorizing the "legal five": ID, IF, IN, IS, IT. Once you have those down, look for the "IO" and "II" (a type of Hawaiian bird, though often spelled "iiwi") exceptions in more advanced dictionaries. You’ll be surprised how much your average score jumps when you stop ignoring the small stuff.

Go open your Scrabble app right now. Try to play "ID" parallel to an existing word. Notice how the points add up from the horizontal and vertical connections simultaneously. That's the moment you stop being a casual player and start being a strategist. Focus on the "glue" words and the big plays will eventually find themselves.
Check the specific dictionary settings in your app—whether it’s the WWF (Words With Friends) dictionary or the NASSC (North American Scrabble) list—as "id" and "it" are universal, but "io" is the one that causes the most dinner-table arguments. Stay sharp. The smallest words often have the biggest impact on the final score.
