English is weird. Honestly, it’s a mess of Germanic roots and stolen French vocabulary that somehow works well enough for us to buy groceries and argue on the internet. But if you’ve ever sat down with a Scrabble board or tried to finish a high-stakes crossword, you’ve probably hit a wall when you realize how few words ending in if actually exist in our daily rotation. It’s a tiny club. There aren't many members.
Most people can name if. Maybe cliff. Then the brain just... stops. We use these sounds constantly, but the spelling patterns of the English language usually prefer a iff (like stiff or sniff) or a ive (like give or live). When you strip away those double consonants and the silent e, you’re left with a very specific, very strange list of linguistic artifacts.
The Scrabble Player’s Survival Guide to If
If you’re staring at a rack of tiles and you’re desperate to hook onto an f, you need to know the shorties. These are the lifeblood of competitive word games.
If. Obviously. It’s the king of the conditional. It's two points that can open up a triple word score if you're lucky.
Then there is arif. It’s not a typo. It’s a real word. In Islamic contexts, an arif is someone who possesses "ma'rifa," or mystical knowledge. It’s a deep, spiritual term, but for a gamer, it’s a four-letter gift from the heavens. You’ll find it in the Oxford English Dictionary and most standard tournament word lists.
What about serif? This is probably the most common word on the list besides the basics. If you do anything with computers, graphic design, or just reading, you know this one. It's those tiny little "feet" at the ends of letters in fonts like Times New Roman. Sans-serif means "without feet." It's a loanword from the Dutch schreef, and it’s basically the only reason some of us win at Bananagrams.

The Mystery of the Single F
Why is this list so short? Linguistically, English has a "rule of three." Usually, short words with a short vowel ending in f, l, or s get doubled. Think fluff, hill, and less. This is called the Floss Rule. Words ending in if like if itself are the exceptions that prove the rule.
Calif. You might see this as caliph more often, but the f ending is a legitimate variant. It refers to a leader in a Muslim civil and religious capacity. It’s old school. It’s historical. And it’s a nightmare for your opponent when you drop it on the board.
Fif. This one is a bit more niche. In some technical or dialect-specific contexts, fif appears as a shortening or a specific notation, though it’s often rejected in stricter dictionaries unless you're playing by very specific house rules. Stick to the ones you can prove with a quick search on Merriam-Webster.
Waif. A classic. A thin, often homeless person, or a piece of property found ownerless. It feels Dickensian. It feels like a word that should have an e at the end, but it doesn't. It’s lean. It’s efficient.

Take motif. In art, literature, or music, a motif is a recurring element or theme. It’s borrowed from the French motif, which explains why it doesn't follow the standard English doubling rules. We see this a lot. When English steals a word, it often keeps the original spelling as a sort of trophy.
Then you have the really obscure stuff like gradif. It’s a term you’ll almost never hear in casual conversation, often related to specific taxonomic or gradient-based descriptions in older scientific texts.
And don't forget tardif. It’s an adjective meaning late-ripening or late-developing, specifically in botany or viticulture (wine making). If you’re a sommelier, you might talk about a tardif harvest. If you’re a normal person, you just say "the grapes stayed on the vine too long."
The Most Famous If That Isn't a Word
We have to talk about Tariff. Wait. Look at it. Double f. It doesn’t count.
This is the trap. People see words like cliff, iff (the logic term for "if and only if"), and riff and think they belong here. They don't. The single f ending is a rare bird. It usually signals that the word has an international passport.

Mastiff. Another fake-out. Look closer. Double f.
Plaintiff. Double f again.
The struggle is real. Finding a word that ends in a single f preceded by an i requires you to look at loanwords and specialized vocabulary.
A Quick Cheat Sheet for Your Next Game
If you're in the middle of a game and the clock is ticking, here is the mental checklist you should run through. Forget the long ones; focus on these:
- If: The 2-letter staple.
- Arif: The secret weapon.
- Serif: The designer's favorite.
- Waif: The literary classic.
- Motif: The artistic standard.
- Calif: The historical variant.
The Cultural Weight of a Tiny Conjunction
Let’s be real: the word if does the heavy lifting for the entire category. Rudyard Kipling’s poem "If—" is one of the most famous pieces of literature in the English-speaking world. It’s a stoic anthem. It’s about the conditions of manhood and resilience.
“If you can keep your head when all about you are losing theirs...” That single word creates a world of possibility and doubt. It’s a conditional operator in coding. if (x > y) { do something }. Without that two-letter word ending in f, our logic systems—both human and machine—would basically collapse.
Actionable Takeaways for Word Lovers
Don't just memorize the list. Understand why they are there. Most of these words are survivors of translation.
- Check the Dictionary: If you’re playing a tournament, always verify arif and calif before the game starts. Some dictionaries are pickier than others about "variant spellings."
- Look for the "Feet": In any visual project, knowing your serifs can actually save you from a design disaster.
- Master the Conditional: In writing, use if sparingly. It’s a powerful word. It creates tension.
- Watch the Doubling: Remember the Floss Rule. If the word feels "English" (like sniff), it probably has two fs. If it feels "foreign" (like motif), it’s more likely to end in a single f.
Next time you’re stuck on a word puzzle, don't panic. Reach for the serif. Look for the motif. The English language is a sprawling, chaotic place, but even in the tiny corner of words ending in f, there’s enough room to win.
