What Is To Explain? | Meaning And Use In Real Writing

You’ve seen teachers write “Explain your answer.” You’ve heard a friend say, “Explain what happened.” Yet the wording to explain can feel slippery when you’re trying to define it, use it in a sentence, or teach it to someone else.

This article clears up two things at once: what the verb explain means, and what the grammar of the phrase to explain is doing. You’ll get plain-English definitions, short examples, and a practical method for writing explanations that don’t confuse your reader.

What Is To Explain? Meaning In Writing And Speech

Explain is a verb used when you want to make something understandable for someone else. You do that by adding the missing pieces: the “why,” the “how,” and the connections between ideas.

When you see to explain, you’re looking at the infinitive form of the verb. It often appears after another verb, like “try,” “need,” “want,” “plan,” or “help.”

• Verb: “Please explain the rule.”
• Infinitive phrase: “Please try to explain the rule.”

Both sentences point to the same action: making the rule clear. The second sentence adds one more action (“try”), and to explain shows what the trying is about.

What “Explain” Asks You To Do

When someone asks you to explain, they’re asking for understanding, not just information. A list of facts can still leave a person confused if the links between those facts are missing.

Think of explanation as building a bridge. Your reader stands on one side with questions. Your job is to place enough stepping stones—definitions, reasons, steps, and examples—so they can cross without guessing.

Three core moves inside most explanations

1. Name the point. Say what you want the reader to understand.
2. Give the reason or method. Share why it’s true or how it works.
3. Show it. Use a small scenario, numbers, or a worked step.

You can stretch those moves into a paragraph, a report, or a full lesson, but the bones stay the same.

“Explain” Vs “Describe” Vs “Define”

These verbs overlap, so people mix them up. Sorting them out makes your writing sharper.

• Define tells what something is, often in one sentence. “A haiku is a short poem with a 5–7–5 syllable pattern.”
• Describe tells what something is like. “A haiku is brief and uses simple images.”
• Explain tells how or why something works or happens. “A haiku feels strong because it strips away extra words and forces each image to carry weight.”

You can combine them, but the order helps. Define first if the word is new. Describe next if the reader needs a picture. Explain when the reader needs the logic.

How The Grammar Of “To Explain” Works

The phrase to explain is an infinitive: to + base verb. It can act like a noun in a sentence, or it can attach to another verb to show purpose or intention.

Common patterns you’ll see

• Verb + to explain: “I need to explain my choice.”
• Noun + to explain: “I have a lot to explain.”
• Adjective + to explain: “It’s hard to explain.”
• Question word + to explain: “She showed me how to explain it step by step.”

If you’re teaching grammar, say it this way: the infinitive phrase names an action, and the rest of the sentence tells who will do it, when, or why.

When People Ask For An Explanation, They Usually Want One Of These

Not every “Explain…” prompt is the same. Sometimes the reader wants reasons. Sometimes they want steps. Sometimes they want a translation into simpler terms.

Dictionary definitions capture the core meaning of the verb well. The Merriam-Webster definition of “explain” centers on making something plain or understandable, which matches how the word is used in school tasks and everyday talk.

Use the table below as a map. It shows what kind of explanation the reader is asking for, plus the writing move that usually satisfies it.

Type of explanation	What the reader is asking	Writing move that works
Reason	Why did this happen?	State the cause, then show the link to the outcome.
Process	How does this work?	Give steps in order, with the “why” for tricky steps.
Meaning	What does this word or line mean?	Define it, then restate it in plain language with a short scene.
Choice	Why did you pick that answer?	Show your rule or criteria, then match it to evidence.
Fix	What went wrong, and how do I repair it?	Name the error, then give a clean, repeatable set of steps.
Comparison	What’s the difference between these two things?	Compare one feature at a time, using the same structure.
Justification	Why is this fair or reasonable?	State the standard, then show how it applies to this case.
Interpretation	What should I take from this data or text?	Point to the evidence, then say what it suggests and why.

How To Write An Explanation That Readers Don’t Misread

Clear explanations feel calm. They don’t rush. They also don’t drown the reader in details that don’t help.

Start with a one-sentence claim

Lead with what you want the reader to understand. If you can’t say it in one sentence, you may not be ready to explain it yet.

• Weak: “There are many reasons this happens.”
• Better: “This happens because the app keeps the old setting until you restart it.”

Add the missing background in small bites

Most confusion comes from assumed knowledge. Fix that by adding short background lines right before the reader needs them. Don’t dump all the background up front.

Show the link between steps

When you list steps, the reader still needs the “why this step exists” for any step that feels random. One short sentence per tricky step is usually enough.

Use a small, concrete illustration

Abstract writing is hard to follow. A small illustration makes your logic visible. The Cambridge Dictionary entry for “explain” also points to making something clear by describing it in more detail, which is what a good illustration does: it adds just enough detail to remove guesswork.

Try this pattern when you write:

1. Claim in one sentence.
2. One reason or step.
3. One illustration that matches the reason or step.
4. Repeat until the reader can reach the same conclusion on their own.

How To Explain An Answer On Tests And Homework

School prompts can be vague. A teacher might write “Explain your answer” and expect a short proof, not a story. A safe approach is to show your rule, then show your evidence.

Use the rule–evidence–link pattern

• Rule: Name the principle or definition you used.
• Evidence: Point to the part of the text, data, or problem that fits the rule.
• Link: Say how the evidence matches the rule.

Here’s how it looks in a math word problem:

• Rule: “Speed equals distance divided by time.”
• Evidence: “The trip was 120 km and took 3 hours.”
• Link: “120 ÷ 3 = 40, so the speed was 40 km/h.”

In a literature question, it works the same way. Your “rule” might be a definition like metaphor, tone, or theme. Your “evidence” is the line from the text. Your “link” is the reason that line fits the definition.

Common Problems That Make Explanations Feel Fuzzy

If you’ve ever written a paragraph that looked fine to you but confused your reader, you’re not alone. These are the patterns that most often cause that gap.

Problem: You skipped the reader’s starting point

You started in the middle, because you already knew the background. Add one sentence that sets the starting point and defines any term that might be new.

Problem: You used “this” with no clear referent

Words like “this,” “that,” and “it” can blur your meaning. Replace them with the noun once or twice, then you can use the pronoun again.

Problem: Your steps aren’t in time order

If step two depends on step three, the reader will stumble. Put steps in the order a person would do them, not the order you thought of them.

Problem: You gave reasons but no link

Reasons can sit next to a claim and still not connect. Add one sentence that spells out the connection. Treat it like showing your work.

The table below is a self-check you can run on any explanation you write.

Check	What to look for	Fix
Clear claim	Can you point to one sentence that states the point?	Write the claim as a single sentence near the top.
Defined terms	Any word a new reader might not know?	Add a short definition right before the first use.
Step order	Could someone follow the steps without guessing?	Reorder steps and add “why” for the tricky one.
Evidence shown	Did you point to data, text, or an observed detail?	Add one concrete detail that supports the claim.
Link stated	Does the reader see how evidence fits your rule?	Add one sentence that connects evidence to the claim.
Reader viewpoint	Did you assume knowledge you never wrote down?	Add one background sentence at the moment it’s needed.
Scope held	Did you wander into side topics?	Cut side lines that don’t change understanding.
Final check line	Could a reader restate your point in their own words?	Add a short restatement that uses different words.

A Simple Template You Can Reuse Any Time You Need To Explain

If you want a repeatable way to write explanations, use this fill-in pattern. It keeps you honest and keeps the reader oriented.

1. Point: “The main idea is ___.”
2. Reason or method: “This happens because ___ / It works by ___.”
3. Proof or illustration: “You can see it when ___.”
4. Result: “So, ___.”

Before you submit or publish, read your explanation out loud. If you stumble, your reader will stumble too. Tighten the sentence. Swap vague words for specific ones. Cut anything that doesn’t help the point land.

Closing checklist for clear explanations

• My first sentence states the point.
• I defined any word a new reader might not know.
• I gave a reason or steps, in order.
• I showed one concrete detail that fits my point.
• I wrote the link between evidence and claim in a full sentence.
• A reader could restate my point after reading once.
