Put and post can both describe doing something with an object, message, or piece of information, but they are not normally interchangeable. Put usually focuses on placing or moving something into a particular position, while post commonly means sending something by mail, publishing information, making an announcement, or assigning someone to a particular place. The correct choice depends on what action you mean.
Quick Answer
Put means to place, move, or position someone or something in a particular place, position, or condition. Post can mean to send something by mail, publish information online, announce information publicly, or assign someone to a particular location or job.
For example, you put your keys on the table, but you post a photo on Instagram. You can also post a letter, especially in British English, meaning to send it by mail.

What Does Put Mean?
Put is a very common verb meaning to move or place someone or something into a particular place, position, or direction.
For example:
- Put the keys on the table.
- She put the milk in the refrigerator.
- He put his phone in his pocket.
- Please put your shoes by the door.
The word put can also be used for abstract ideas and situations. You can put something into practice, put pressure on someone, put an idea into words, or put someone in a difficult position. Cambridge and Oxford both document this broader range of meanings.
Put in Different Contexts
Physical placement:
Put the laptop on the desk.
Writing:
Put your name at the top of the page.
Expression:
I don’t know how to put my feelings into words.
Condition or situation:
The mistake put us in a difficult position.
So, put is not limited to physical objects.
What Does Post Mean?
Post has several meanings, so context is especially important.
One common meaning is to send a letter or parcel by mail. In British English, post is commonly used where American English often uses mail.
I need to post this letter today.
Another common meaning is to publish or make information available online.
She posted a photo on Instagram.
He posted a comment on the website.
Post can also mean to make information publicly available, such as an announcement or warning:
The company posted a notice about the change.
Another meaning is to assign someone to a particular place as part of their work:
She was posted to London for two years.
Oxford lists these as distinct uses of the verb post, including mailing, online publishing, official announcements, and job assignments.
What Is the Difference Between Put and Post?
The easiest way to understand the difference is to look at the main action.
Put focuses on placement or position.
Post focuses on sending, publishing, announcing, or assigning.
Compare:
Put the letter on the desk.
Here, the important action is placing the letter on the desk.
Post the letter.
Here, the important action is sending the letter through the postal system.
Another example:
Put the photo on your desk.
The photo is being physically placed somewhere.
Post the photo online.
The photo is being published or shared so other people can see it.
This distinction is more useful than trying to memorize a list of isolated definitions.

Common Mistakes With Put and Post
Mistake 1: Using put when you mean publish
Incorrect:
I put a new video on YouTube yesterday.
This sentence can be understood, and put can sometimes be used informally to mean make something available, but posted is more precise when the intended meaning is publishing content online.
Better:
I posted a new video on YouTube yesterday.
Why: Post specifically describes making information, photos, videos, or other content available online.
Mistake 2: Using post when you simply mean physical placement
Incorrect:
Please post the keys on the table.
Correct:
Please put the keys on the table.
Why: The action is physical placement, so put is the natural verb.
Mistake 3: Thinking post only means social-media publishing
Incorrect idea:
Post always means sharing something online.
Correct idea:
Post has several meanings. It can refer to mailing a letter, publishing online, making an announcement, or assigning someone to a location.
Mistake 4: Thinking put only applies to physical objects
Incorrect idea:
Put can only be used for things you can touch.
Correct idea:
You can put an idea into words, put pressure on someone, or put someone in a difficult situation.
Can Put and Post Be Used Interchangeably?
Usually not.
They can overlap in certain contexts, especially when something is being made available somewhere, but their normal meanings are different.
Compare:
Put the photo on the wall.
This means physically place the photo on the wall.
Post the photo on the website.
This means publish the photo online.
The context can occasionally make both verbs possible, but changing the verb can change the meaning or make the sentence sound less natural.
The safest approach is to identify the action first:
- Place it somewhere → put
- Send it by mail → post
- Publish it online → post
- Make an announcement → post
- Assign someone to a location → post
How to Remember the Difference
Use this simple rule:
PUT = PLACE
POST = SEND or PUBLISH
Think of put as answering:
“Where does it go?”
Think of post as answering:
“Is it being sent or made available to someone?”
For example:
Put the book on the shelf.
The book is being placed.
Post the article online.
The article is being published.
