Quick Answer: Correct Phrase Explained
Here’s the simple truth before we unpack it deeply:
| Phrase | Correct? | When to Use |
| Case in point | ✅ Yes | When giving an example that supports what you just said |
| Case and point | ❌ No | It’s not a correct expression in English |
Case in point is the phrase you want. It means a relevant example or evidence that illustrates a point you’re making.
People say case and point because it sounds similar. But those words together don’t form a phrase with meaning. Later, we’ll talk about why that mistake happens.
What “Case in Point” Actually Means
At its core, case in point is a phrase writers and speakers use to introduce an example that directly supports or proves what they’re talking about.
It’s like saying, “Here’s proof. Pay attention.”
Let’s break it down:
- Case = an instance, situation, or example
- In point = relevant to the argument or topic
So when you say case in point, you mean:
“Here’s a specific example that directly fits the idea I just shared.”
Think of it as pointing to evidence with your words.
Simple Pattern
You can usually spot the structure like this:
[Your statement]. Case in point: [Relevant example].
Here’s a real sentence:
Remote work can boost productivity. Case in point, companies that adopted flexible schedules often report higher output.
That’s the phrase doing exactly what it’s supposed to do — introducing evidence.
The True Origin of “Case in Point”
Understanding where a phrase comes from helps you remember its meaning.
Legal Roots
The phrase comes from legal language. In law:
- A case is a legal dispute or example used to illustrate a rule.
- In point means relevant to the question at hand.
So case in point literally meant “a legal case relevant to this issue.”
Over time, writers and speakers borrowed it for everyday use. Today it simply means an example that matters.
How the Phrase Evolved
- 1800s: Lawyers used it to talk about precedent cases
- Early 1900s: Academics and writers adopted it
- Today: It’s common in essays, business writing, speeches, and casual conversation
Knowing the phrase started in law makes it easier to remember there’s no “and” in it.
Think: We’re placing the case in the point we’re making — not adding a point.
Why People Say “Case and Point” by Mistake
Let’s clear this up right now.
People say “case and point” because:
- It sounds similar to “case in point”
- We’re used to pairs like “salt and pepper” and “black and white”
- People learn language by ear, not by rules
This kind of mistake has a name: it’s an eggcorn. That’s when we create a similar-sounding but incorrect phrase because it feels right. Like:
- saying “for all intensive purposes” instead of “for all intents and purposes”
- saying “old-timer’s disease” instead of “Alzheimer’s disease”
But here’s the bottom line:
👉 Case and point is a misunderstanding of the correct phrase, not a variant.
It’s wrong. Period.
How to Use “Case in Point” Correctly
You now know the phrase is correct. But how do you use it smoothly?
Here are real-life templates that help.
When Starting a Sentence
Put the example right up front.
Case in point, students who take short breaks every hour learn faster.
When Following a Statement
This is the most common way:

In the Middle of a Sentence
You can also weave it in:
A strong argument needs evidence, case in point, data that backs up claims.
When NOT to Use “Case in Point”
This phrase sounds powerful. But don’t overuse it.
Here’s when to avoid it:
- When you don’t have a specific example
Bad: My idea will work. Case in point, it’s good. - When the example doesn’t prove your point
Bad: I like apples. Case in point, bananas are tasty. - When you’re repeating yourself
Example: “It’s true. Case in point…” when no evidence follows
Instead, use plain words like:
- for example
- for instance
- consider this
Those are lighter and fit better when you’re not proving a point.

Grammar Breakdown — Why “In” Matters
Let’s unpack the structure so it sticks.
- Case = an example
- In = shows the example is within or relevant to the discussion
- Point = your main idea or argument
If you remove in, the logical connection breaks:
Case point ❌
Doesn’t show relevance
If you replace in with and:
Case and point ❌
It sounds like two unrelated words
So:
Case in point = “Example that fits the point”
That tiny word in carries the connection.

Trick 1: Think of “Putting an Example In the Point”

- You drop the case into it
- That hit the example spot perfectly
Trick 3: Replace with “Here’s Proof”

If it doesn’t, rethink your phrase.
