What In A Sentence Example | Real Uses And Punctuation

“What” looks simple until you try to write with it. One minute it’s a straight question. Next, it’s the glue inside a longer sentence. Then it’s an exclamation that adds attitude.

This page gives you clear patterns, then model sentences you can adapt for school writing, emails, chat, and essays.

What In A Sentence Example In Real Writing

When you build a what in a sentence example, start by picking the job “what” is doing. That choice controls word order, punctuation, and tone.

In most writing, “what” lands in one of these buckets: a direct question, an indirect question inside a statement, a clause starter (“What I mean is …”), a reference back (“That’s what …”), or an exclamation (“What a …!”).

One quick test: replace “what” with “the thing that.” If the sentence still makes sense, you’re using “what” as a clause builder. If it doesn’t, you’re probably asking a question. That tiny swap can save you from punctuation mistakes, especially when you’re writing fast during an exam.

“What” As A Direct Question

Direct questions usually place “what” at the front. Use a question mark at the end. Keep the question narrow so the reader knows what you want.

• What are the grading rules for this assignment?
• What did you mean by “sources” in the rubric?
• What should I cut from the introduction?

“What” Before A Noun

Sometimes “what” is paired with a noun: what chapter, what plan, what reason. That’s still a question, but it points the reader toward the category you’re asking about.

• What chapter covers relative clauses?
• What section of the report needs citations?

“What” Inside An Indirect Question

An indirect question sits inside a statement. It often follows verbs like know, wonder, ask, explain, show, and tell. Indirect questions don’t use a question mark unless the whole sentence is a question.

These are statements:

• I wonder what the author meant in the last line.
• She explained what the diagram is showing.

These are full questions:

• Do you know what the author meant in the last line?
• Can you tell me what time the bus arrives?

Watch the word order. In indirect questions, you usually don’t invert the subject and verb. So you write “what time the bus arrives,” not “what time does the bus arrive” inside that clause.

“What” As A Clause Starter

This pattern works well in academic writing, feedback, and planning notes. The structure looks like this: “What + clause + is/was + noun phrase.”

• What I’m missing is a clear topic sentence.
• What the data shows is a steady rise in errors.
• What matters here is the definition, not the rumor.

This shape keeps you focused. You name the messy situation first, then you name the real point after “is.”

“What” As “The Thing That” In One Package

“What” can also stand for “the thing that.” You’ll see it in sentences where “what” introduces the idea, then the rest of the clause explains it. This use is common in essays and in daily speech.

• Take what you need and leave the rest.
• He admitted what he did, then apologized.
• What you choose now affects the final outline.

This pattern is handy when you don’t want to name the thing yet. The clause after “what” does the naming for you.

“What” After A Preposition

You can place “what” after a preposition in indirect-question structures. It’s common in formal writing, and it keeps the sentence smooth.

• She explained what the rule is about.
• They argued about what the word should mean in this context.

If you want a definition check, see Merriam-Webster’s “what” entry. For clause grammar, this Purdue OWL page on relative pronouns is a handy refresher.

“That’s What …” To Point Back

Use “that’s what” when you want to refer back to something already mentioned. It’s common in conversation and can work in reflective writing when the reference is clear.

• That’s what I meant by “too broad.”
• That’s what made the transition feel sudden.

“What” In Exclamations

Exclamations use “what” with a noun phrase, often “what a” or “what an.” This isn’t a question, so it takes an exclamation point or a period, depending on tone.

• What a mess this citation list turned into.
• What an awkward sentence that was.

In more formal writing, you can use the “what a” structure with a period for a calmer voice: “What a strange claim.”

Picking The Right Punctuation With “What”

Punctuation trips writers most. Match the punctuation to the sentence’s job, not to the word “what.”

Question Marks For Direct Questions

• What changed between the first draft and the second?
• What do you want the reader to feel at the end of the story?

Periods For Indirect Questions

• I can’t tell what the speaker is implying.
• We discussed what the next step should be.

Commas After Fronted “What” Clauses

When a “what” clause comes first, you often set it off with a comma when the main clause follows right after.

• What I want to know, though, is whether the claim is testable.
• What she wrote, at least in the first paragraph, sounds confident.

Exclamation Points And Tone

Exclamation points are strong. Use them in chat or personal writing. In school writing, a period often fits better.

• What a surprise!
• What a surprise.

Common Mistakes With “What” And Clean Fixes

Most errors with “what” come from mixing patterns. The writer starts a direct question, then drifts into an indirect-question structure. Or they try to use “what” like “that” or “which.”

Mixing Direct And Indirect Question Word Order

• Direct: What did she say?
• Indirect: I heard what she said.
• Indirect: I wonder what she said.

If you write “I wonder what did she say,” it sounds wrong because it mixes patterns.

Using “What” When You Mean “Which”

“What” asks for open-ended information. “Which” asks you to choose from a known set. Many teachers treat this as a style point, not a strict rule.

• What book should I read next? (Any book)
• Which book should I read next? (From a list)

Using “What If” And “So What” With Care

“What if” starts a conditional question. It works when you’re testing an idea, planning, or checking a risk. Keep the follow-up concrete so it doesn’t feel like a vague thought.

• What if the source is biased—do we still cite it?
• What if the deadline changes again?
• What if I cut this sentence—does the paragraph still make sense?

“So what?” can sound sharp, so use it when you’re pushing for relevance, not when you’re talking down to someone. In essays, you can turn the same move into a calmer line: “So what does this claim lead to?”

Overusing “What” In One Paragraph

In feedback writing, it’s easy to stack “what” starters: “What I think is… What you need is… What this does is…” That rhythm can get heavy.

Mix in other shapes:

• The draft needs a clearer topic sentence.
• A stronger example would make the claim easier to follow.
• The conclusion repeats the introduction too closely.

Sentence Patterns You Can Copy

Below are ready templates. Swap in your own nouns, verbs, and details. If you’re building a what in a sentence example for homework, pick one pattern, then customize it with your topic words.

Templates For Questions

• What does ______ mean in this context?
• What evidence backs up ______?
• What would change if ______ happened?

Templates For Indirect Questions

• I’m not sure what ______ refers to.
• Please explain what ______ means in your own words.
• She asked what ______ was supposed to do.

Templates For Clarity Statements

• What I’m trying to say is ______.
• What matters most is ______.
• What went wrong was ______.

If a template feels stiff, add one small human marker. A short side phrase can help: “What I’m trying to say is, honestly, ______.”

Table Of “What” Templates By Goal

Use this table when you want a sentence that fits a specific purpose.

Goal	Structure	Model Sentence
Ask for meaning	What does + term + mean … ?	What does “bias” mean in this article?
Ask for action	What should I/we + verb … ?	What should we revise before we turn it in?
Ask for a detail	What + noun + do/does … ?	What section does your teacher grade hardest?
State your need	What I need is + noun phrase	What I need is one clear source I can quote.
State your point	What I mean is + clause	What I mean is that the claim needs a limit.
Point back	That’s what + clause	That’s what made the argument feel shaky.
Add reaction	What a/an + noun phrase	What a tough paragraph to rewrite.
Signal surprise	Guess what, + clause	Guess what, the deadline moved again.

How To Write Your Own “What” Sentence In Four Steps

If you want to create your own line from scratch, use a short build process. It keeps you from mixing patterns and saves time when you’re editing.

1. Pick the job. Decide if “what” is asking, linking, or reacting.
2. Choose the pattern. Use one from the tables, then fill in your topic words.
3. Match the punctuation. Question mark for direct questions, period for statements, exclamation point only when the tone calls for it.
4. Read it once out loud. If you stumble, tighten the word order or cut extra words.

Edit trick: if your sentence contains “I wonder,” “I don’t know,” or “Tell me,” treat the “what” part as an indirect question and keep normal word order.

Final Checklist For Clear “What” Sentences

• Does “what” have one clear job in the sentence?
• Is it a direct question or an indirect question?
• Does the punctuation match that job?
• Can a reader answer the question, or follow the reference, without guessing?
• Did you avoid stacking too many “what” starters in one paragraph?

Once you’ve got those boxes checked, your writing sounds natural, and “what” stops feeling like a trap word.

Yep, once it clicks, you’ll spot the pattern in minutes each time.
