Trust vs Mistrust
Both words describe how we feel about another person, a situation, or something we believe to be true. The difference is mainly about confidence versus doubt.
If you trust someone, you believe that person is honest, reliable, or likely to do the right thing. If you mistrust someone, you feel that the person may not be honest or reliable.
You have doubt or suspicion about them.
English learners sometimes find these words confusing because mistrust looks like the opposite of trust, and in many cases it is.
However, the two words can be used in slightly different ways depending on the situation.
For example, you might say, “I trust my brother with my money.” This means you feel confident that he will take care of it.
On the other hand, “I mistrust that salesman” means you have doubts about his honesty.
Understanding this difference can make your English sound much more natural.
It is especially useful when talking about relationships, friendship, business, promises, information, and personal feelings.
By the end of this guide, you will know what each word means, how to use it correctly, how their grammar works, and how to choose the right word in everyday English.

A Common Confusion About “Trust”
Many learners think trust always means believing that someone is telling the truth. That is not quite enough.
Trust can also mean relying on someone to do something properly.
For example:
Trust vs Mistrust
This does not only mean Sarah is honest. It also means the speaker believes Sarah is responsible and capable.
So, trust can involve honesty, reliability, safety, or confidence.

Mistrust means a lack of trust. If you mistrust someone, you have doubts about that person’s honesty, intentions, or reliability.
Like trust, mistrust can be used as both a noun and a verb.
As a verb:
Trust vs Mistrust
This means I do not feel confident about him or his intentions.
As a noun:
There is a lot of mistrust between the two groups.
This means the two groups do not trust each other.
The prefix mis- often gives the idea of something being wrong, mistaken, or negative. In mistrust, it creates the idea of doubt or lack of confidence.
When Should You Use “Mistrust”?
Use mistrust when you want to say that someone has doubts about another person or thing.
For example:
Trust vs Mistrust
The speaker feels that such people may not be reliable.
You can also mistrust information:
She mistrusted the report because some numbers looked wrong.
Here, she does not fully believe the report.
Mistrust is often connected with suspicion.
However, it does not always mean that you are certain someone is dishonest. You may simply feel that something is not right.

As a verb, mistrust can take a direct object.
Subject + mistrust + object

A Common Confusion About “Mistrust”
Some learners think mistrust means exactly the same thing as hate or dislike.
It does not.
If you dislike someone, you simply do not like that person.
If you mistrust someone, you doubt that person’s honesty, intentions, or reliability.
For example:
I dislike Tom.
This tells us nothing about whether Tom is trustworthy.
But:
Trust vs Mistrust
This tells us that the speaker has doubts about Tom.
Difference Between Trust and Mistrust
The simplest difference is:
Trust = confidence
Mistrust = doubt or lack of confidence
They are opposite ideas in many situations, but the emotional strength can depend on the context.
| Word | Part of Speech | Basic Meaning | Feeling | Example |
|---|---|---|---|---|
| Trust | Noun/Verb | Confidence in someone or something | Positive | I trust her. |
| Mistrust | Noun/Verb | Doubt about someone or something | Negative | I mistrust her. |
Meaning Difference
Compare these sentences:
I trust him.
The speaker believes he is reliable or honest.
I mistrust him.
The speaker has doubts about him.
The difference is quite strong.
Imagine that a friend asks you to keep a secret. If you trust your friend, you feel comfortable sharing the information.
If you mistrust your friend, you may worry that the secret will be shared with someone else.
Usage Difference
Trust is much more common in everyday English.
People frequently say:
Trust vs Mistrust
I trust you.
Don’t trust strangers.
You can trust her.
Mistrust is correct, but it can sound more formal or serious, especially when used as a noun.
For example:
There is mistrust between the two countries.
This sounds more formal than:
The two countries don’t trust each other.
Both can be correct, but the second is more conversational.
Grammar Logic
Both words can function as nouns and verbs.
Trust as a verb:
I trust him.
Trust as a noun:
Trust vs Mistrust
More naturally, English often uses:
I have confidence in him.
or:
There is trust between us.
Mistrust as a verb:
I mistrust him.
Mistrust as a noun:
Trust vs Mistrust
Sentence Structure
The basic verb structure is simple:
Subject + trust + object
She trusts me.
Subject + mistrust + object
She mistrusts me.
You can also use:
Subject + trust + object + to + verb
Trust vs Mistrust
And:
Subject + mistrust + object
I mistrust him because he has lied before.
The words can therefore appear in similar grammatical positions, but their meanings point in opposite directions.
Grammar Rules You Must Remember
Rule #1: Trust Can Be a Verb or a Noun
As a verb:
I trust my parents.
As a noun:
Trust vs Mistrust
When trust is a verb, it describes an action or feeling. When it is a noun, it describes the idea or quality itself.
Rule #2: Mistrust Can Also Be a Verb or a Noun
As a verb:
She mistrusts him.
As a noun:
Trust vs Mistrust
Do not assume that mistrust can only be used as a verb.
Rule #3: Use “Trust” for Confidence
When you believe someone is reliable, use trust.
I trust my teacher.
We trust our driver.
She trusts her friend.
The word shows confidence rather than doubt.
Rule #4: Use “Mistrust” for Doubt or Suspicion
When you feel that someone or something may not be reliable, mistrust can be used.
I mistrust his motives.
They mistrust the new system.
She has a mistrust of strangers.
In casual conversation, however, speakers often choose simpler expressions such as don’t trust, have doubts about, or be suspicious of.
Common Mistakes Students Make
English learners often make mistakes with these words because their meanings are closely connected.
Mistake 1: Thinking “Mistrust” Means “Dislike”
Incorrect understanding:
Trust vs Mistrust
This could be possible, but mistrust does not simply mean dislike.
A clearer sentence would be:
I mistrust him because I don’t think he is honest.
The second sentence explains the reason for the mistrust.
Mistake 2: Using “Mistrust” in Every Negative Situation
You do not need mistrust whenever something feels negative.
For example:
I don’t like this restaurant.
This means you dislike the restaurant.
You would not normally say:
Trust vs Mistrust
That would suggest you have doubts about its safety, honesty, quality, or reliability.
Mistake 3: Forgetting the Third-Person “-s”
Incorrect:
She trust him.
Correct:
She trusts him.
Incorrect:
Trust vs Mistrust
Correct:
He mistrusts the company.
Remember the normal present-simple rule: he/she/it + verb-s.
Mistake 4: Confusing “Trust” With “Believe”
These words can sometimes be similar, but they are not identical.
I believe his story.
This focuses on whether you think the story is true.
Trust vs Mistrust
This focuses more broadly on your confidence in the person.
You can believe something someone says without fully trusting that person.
Mistake 5: Thinking Mistrust Means Complete Proof of Dishonesty
Mistrust does not necessarily mean you know someone is lying.
For example:
I mistrust his explanation.
This means you have doubts. You may not have proof that he is lying.
That distinction is important.
Easy Trick to Remember the Difference
Here is a very simple memory trick:
Trust = “I feel safe believing you.”
Mistrust = “I have doubts about you.”
Think about two friends.
Your friend says:
“I will return your book tomorrow.”
If you trust your friend, you think:
“Okay, I believe you.”
Trust vs Mistrust
“I’m not sure you’ll return it.”
Another easy trick is to notice the mis- at the beginning of mistrust.
The word mis- often gives a negative sense.
So remember:
Trust → confidence
Mistrust → doubt
You can also remember it with a simple scale:
Trust ← confidence | doubt → Mistrust
When confidence goes up, trust becomes stronger.
When doubt grows, mistrust becomes stronger.
One more useful point: in everyday conversation, “not trust” is often more natural than “mistrust.”
For example:
Trust vs Mistrust
This is very common.
Trust vs Mistrust
This is also correct, but it can sound more deliberate or formal.
