Things Have or Has Changed
They may ask, “Should I say things have changed or things has changed?” The two forms look similar, but only one is correct.
This confusion happens because learners often focus on the word changed and forget to check the subject.
In English, the helping verb must agree with the subject. A singular subject usually works with has, while a plural subject usually works with have.
The word things is plural. It means more than one thing. Therefore, we say:
Things have changed. ✅
We do not say:
Things Have or Has Changed
This grammar point is useful in daily conversations. You may use it when talking about changes in your life, work, school, family, town, or relationships. For example:
Things have changed since we were children.
The sentence means that life is different now from how it was before.
After reading this guide, you will understand why “things have changed” is correct, when to use have and has, how the present perfect tense works, and how to avoid common mistakes.
You will also see simple examples, daily conversations, practice questions, and easy memory tricks.

Difference Between “Things Have Changed” and “Thing Has Changed”
The main difference is the number of things being discussed.
| Feature | Things have changed | Thing has changed |
|---|---|---|
| Subject | Things | Thing |
| Subject type | Plural | Singular |
| Helping verb | Have | Has |
| Meaning | More than one thing is different | One thing is different |
| Correct structure | Plural + have + changed | Singular + has + changed |
| Example | Things have changed at school | One thing has changed at school |
Usage difference
Use things have changed when several parts of a situation are different.
For example:
Things have changed in our family.
This may mean that several changes happened. Perhaps someone moved away, a child started school, or the family changed its daily routine.
Use a thing has changed when you are talking about one specific change.
For example:
One thing has changed in our family.
This means that only one important detail is different.
Grammar logic
The grammar rule is based on the subject.
Things is plural:
Things have changed.
Thing is singular:
Things Have or Has Changed
The same pattern appears with many other nouns:
The plans have changed.
The plan has changed.
The rules have changed.
The rule has changed.
The people have changed.
The person has changed.
Sentence structure difference
Plural structure:
Plural subject + have + past participle

Meaning comparison
Look at these examples:
Things have changed between us.
This means that the relationship is different in several ways.
Something has changed between us.
This means that one unknown or unclear change has happened.

Grammar Rules You Must Remember
Rule #1: Use “have” with plural subjects
When the subject names two or more people or things, use have.
The students have finished the lesson.
My friends have changed their plans.
Things have changed.
The subject comes before have, so check whether it is singular or plural.
Rule #2: Use “has” with singular subjects
Use has with one person, one thing, or a third-person singular pronoun.
My brother has changed jobs.
The weather has changed.
She has changed her mind.
The subject is singular in each sentence, so has is correct.
Rule #3: Use “have” with I, you, we, and they
These words follow a special pattern.
I have improved my English.
You have done a great job.
We have changed our schedule.
They have moved to a new house.
Even though I means one person, it uses have, not has.
Rule #4: Use the past participle after “have” or “has”
The present perfect tense needs:
Have/has + past participle
Examples:
Things Have or Has Changed
She has gone home.
Things Have or Has Changed
He has written a letter.
Do not use the simple past form after have or has when the verb is irregular.
Wrong:
She has went home. ❌
Correct:
She has gone home. ✅
Things Have or Has Changed
They changed the plan yesterday.
They have changed the plan.
The first sentence uses the simple past. The second sentence uses the present perfect.
Common Mistakes Students Make
Many mistakes happen because learners remember the words have and has but forget to check the subject.
Mistake 1: Using “has” with “things”
Wrong:
Things has changed. ❌
Correct:
Things have changed. ✅
Why?
Things is plural. Plural subjects take have.
Mistake 2: Using “have” with a singular noun
Wrong:
The situation have changed. ❌
Correct:
The situation has changed. ✅
Why?
Situation is singular. Singular subjects take has.
Mistake 3: Using “changed” without a helping verb
Wrong:
Things changed since last year. ⚠️
Correct:
Things have changed since last year. ✅
The first sentence may be possible in some contexts, but it does not clearly show the present perfect meaning. When the past change still matters now, have changed is often the better choice.
Mistake 4: Saying “things is changed”
Wrong:
Things Have or Has Changed
Correct:
Things have changed. ✅
The phrase have changed shows that a change happened.
The phrase is changed usually has a different meaning and may describe an action done to something.
For example:
The password is changed every month.
This means someone changes the password regularly.
Mistake 5: Using “has” after “people”
Wrong:
People has changed. ❌
Correct:
Things Have or Has Changed
The word people is plural.
Easy correction tip
Things Have or Has Changed
How many people or things does the subject mean?
If it means more than one, use have.
If it means one, use has.
Easy Trick to Remember the Difference
A simple memory trick is:
Many = have. One = has.
Think about the subject first.
Things means many things.
Therefore:
Things Have or Has Changed
Everything may sound like many things, but grammatically it is singular.
Therefore:
Everything has changed.
This is an important point.
Compare:
Things have changed. ✅
Everything has changed. ✅
Why are the helping verbs different?
The word things is a plural noun.
The word everything is an indefinite pronoun that takes a singular verb.
You can also use this short pattern:
He, she, it = has
I, you, we, they = have
For nouns:
One thing = has
Many things = have
Imagine one book and several books.
The book has changed.
The books have changed.
The same rule works with thing and things.
