You’ve probably been there. You're typing out a quick email or finishing a thought in a text, and you realize your sentence is about to land flat on the word "is." You pause. Your thumb hovers over the backspace. Somewhere in the back of your mind, a middle-school English teacher is shaking their head, or maybe you just feel like the sentence sounds... unfinished.
So, can you end a sentence with is without looking like you’ve forgotten how to speak English?
The short answer is yes. Absolutely. But the long answer is a bit more interesting because it involves the difference between "proper" grammar and how humans actually communicate. Most of the fear around this comes from a misunderstanding of "terminal prepositions" or "hanging verbs," but "is" is a different beast entirely. It’s a linking verb. It’s the glue of the English language. Sometimes, the glue just ends up at the edge of the paper.
Why People Think You Can't Do It
Language myths die hard. We’ve been told for decades not to end sentences with prepositions—a "rule" that was basically made up by 18th-century grammarians who wanted English to behave more like Latin. But "is" isn’t even a preposition. It’s a form of the verb "to be."
There is no formal rule in the Chicago Manual of Style or the AP Stylebook that forbids ending a sentence with a verb. In fact, trying to move the "is" just to satisfy some imaginary rule often makes you sound like a Victorian ghost.
Think about this: "I don't know who he is."
If you try to "fix" that to avoid ending with "is," you get something like, "I know not his identity."
Nobody talks like that. It's weird. It’s clunky. It feels like you’re trying too hard to be smart, and in the process, you’ve lost the point of the conversation. Grammar exists to facilitate clarity, not to act as a cage.
The Mechanics of the "Hanging Is"
Most of the time, when we end a sentence with "is," we are dealing with an interrogative or a relative clause. This happens constantly in spoken English.
Imagine you’re at a party. You see someone across the room who looks familiar. You turn to your friend and ask, "Do you know who that is?"
That is a perfectly grammatical, natural sentence. In this case, "is" functions as the main verb of the dependent clause "who that is." Because the clause comes at the end of the sentence, the verb naturally takes the final position. This is just how English syntax works.
Examples That Work Perfectly
Sometimes the word "is" carries the heavy lifting of the entire thought.
- "It is what it is."
- "I’m curious about what the truth is."
- "She isn't coming, but her brother is."
- "The problem is not the cost; the problem is what the value is."
In that third example—"but her brother is"—we are using something called ellipsis. We are omitting the word "coming" because it’s already understood from the first half of the sentence. If you were forced to move the "is," the sentence would break.
When It Actually Sounds Bad
Just because you can do something doesn't mean you always should.
Context is everything. While ending with "is" is grammatically sound, it can sometimes create a "weak" ending. In writing, the last word of a sentence is the one that lingers in the reader's mind. It's the "power position."
If you end on a small, unstressed word like "is," your sentence might lose its punch. Compare these two:
- "The most important thing for a leader to possess is." (Wait, what? This is actually an incomplete thought.)
- "Confidence is the most important thing for a leader to possess."
The first one isn't just a "hanging is"—it’s a broken sentence. You’ve left the reader waiting for the predicate nominative. This is where the confusion usually starts. People confuse a valid terminal "is" with an incomplete sentence.
The Identity Crisis of "Is"
There’s also the issue of emphasis. Linguists like Steven Pinker have noted that English speakers naturally prefer to end sentences with "heavy" information. We like nouns. We like punchy verbs.
"Is" is a "state of being" verb. It’s static. If you’re writing a high-stakes legal brief or a cover letter, ending multiple sentences with "is" can make your prose feel repetitive and thin. It’s not "wrong," but it might be "weak."
The Comparison Trap
You’ll often see "is" at the end of sentences involving comparisons.
"He is much taller than his father is."
Strictly speaking, the "is" at the end is redundant. You could just say, "He is much taller than his father." In this scenario, most editors would tell you to chop the final word. Not because it’s ungrammatical, but because it’s unnecessary baggage. Wordiness is the enemy of good SEO and good storytelling.
However, if you’re trying to mimic a specific character's voice in fiction, or if you want to emphasize the state of being, keeping it might be the right call.
Breaking the "Latin" Habit
We have to talk about John Dryden. He was a 17th-century poet who started the whole "don't end a sentence with a preposition" trend. He decided that since you can't do it in Latin, you shouldn't do it in English.
The problem? English is a Germanic language. Our roots are completely different. We love phrasal verbs. We love putting little words at the end of sentences.
If we applied Dryden's logic to "is," we would be stripping the language of its natural rhythm. If you find yourself overthinking whether you can you end a sentence with is, remember that even the most prestigious publications in the world—The New Yorker, The New York Times, The Economist—do it all the time.
Actionable Tips for Better Sentence Endings
If you’re staring at a sentence ending in "is" and it feels "off," don't just panic and move it. Run it through this quick mental filter:
- Is it an ellipsis? If you’re saying "She is" as a shorthand for "She is [doing the thing we just talked about]," leave it alone. It’s clean.
- Is it a question? "Who do you think he is?" is a great sentence. Don't touch it.
- Is it "What it is"? This is an idiom. Changing it makes you look like a robot.
- Does it feel weak? If the sentence feels like it’s fizzling out, try flipping the structure. Move your "power word" (the noun or the action) to the end.
The Professional Perspective
Grammar girl Mignon Fogarty and other modern linguists generally agree: focus on clarity over archaic rules. If your reader understands exactly what you mean, and the sentence flows well, you’ve won.
In digital marketing and SEO, we often prioritize "conversational" language. Why? Because that’s how people search. People don't type "To whom does this belong?" into Google. They type "Who does this belong to?"
The same applies to the word "is." If you’re writing an article about a person’s identity, you might naturally write, "Most people have no idea who this influencer actually is." That’s a great, clickable, understandable sentence.
Common Scenarios Where "Is" Works Best
Sometimes, putting "is" at the end is the only way to keep the focus where it belongs.
Think about defining terms.
"What we need to determine is what 'success' really is."
In this case, you are comparing two different concepts of success. The first "is" acts as a bridge, and the second "is" closes the thought. If you tried to rewrite this to avoid the ending, you’d likely end up with something convoluted like "The definition of 'success' requires our determination."
Ugh. No thanks.
Dialects and Regionalisms
In some dialects, especially in parts of the UK or certain American regional speech patterns, the terminal "is" gets used even more frequently for emphasis. While you might want to tighten that up for a formal business report, in a blog post or a creative piece, it adds flavor.
How to Check Your Work
If you’re still worried, use a tool like Grammarly or Hemingway, but take their advice with a grain of salt. These tools are programmed with "general" rules. They might flag a terminal "is" as a "weak ending."
Your job as a writer is to decide: is it weak, or is it natural?
Next Steps for Your Writing:
Check your current draft for any sentences ending in "is." Read them out loud. If you trip over the ending, or if you feel like you're left hanging, try to swap the subject and the predicate. If it sounds like a normal person talking, keep it.
The goal isn't to follow rules that were made up 300 years ago. The goal is to write things that people actually want to read. Don't let a tiny word like "is" stop your flow.
Practical Summary Table of Usage
| Sentence Structure | Is it okay to end with "is"? | Why? |
|---|---|---|
| Questions | Yes | Natural syntax for "who/what" questions. |
| Ellipsis | Yes | Avoids unnecessary repetition of the main verb. |
| Idioms | Yes | Phrases like "It is what it is" are fixed. |
| Incomplete thoughts | No | If you've forgotten the rest of the sentence. |
| Formal academic papers | Use sparingly | Can be seen as informal or "weak" by strict professors. |
Refining Your Style
To truly master this, start noticing how often you hear "is" at the end of sentences in movies or podcasts. You'll realize it's everywhere. The more you notice it, the less "wrong" it will feel.
- Review your most recent three blog posts.
- Find every sentence ending in a verb.
- Determine if the sentence would be stronger if a noun took that spot.
- If the "is" feels necessary for the rhythm, leave it.
The reality of 2026's writing landscape is that authenticity beats "perfect" grammar every time. Google's algorithms are increasingly focused on "Helpful Content" and "Experience, Expertise, Authoritativeness, and Trustworthiness" (E-E-A-T). Writing like a real human—with all our weird, sentence-ending "is" habits—actually helps your SEO more than writing like a sterile grammar textbook.
Stop worrying about the ghost of your 7th-grade teacher. Write the sentence. If it ends with "is," so be it.
