The short answer
Interjections express reactions: oh, wow, ouch, and phew are examples. A comma often connects a reaction to a sentence, while an exclamation mark can add emphasis.
Oh, I didn't see you there.
Why it works: The comma connects Oh to the sentence. Oh! would also be possible with a different emphasis.

Touching a hot frying pan
Ouch! That hot pan burned my finger.

Choose punctuation for emphasis
The problem: I never know whether to put a comma or an exclamation mark after my reaction word.
A comma often joins a short word to the rest of a sentence: Oh, I forgot. An exclamation mark gives it a strong break: Oh! I forgot. Both can be correct. Choose the mark that suits the voice you have in mind.
A comma links Oh to the rest of the sentence.
Oh, I forgot my hat at home.
An exclamation mark sets Oh apart. This form is correct too.
Oh! I forgot my hat at home.
-
Well, I guess we can start now.
Why it works: The comma separates the opening word from the sentence.
-
Look out! A car is turning.
Why it works: The exclamation mark gives this warning emphasis.
Your turn
Which version uses an exclamation mark to set the reaction apart?
Answer: Ah! That dog jumped right at me.
Show the answer
Answer: Ah! That dog jumped right at me.
The mark gives Ah its own strong break. You could also use a comma here and still mean that you felt afraid.
Choose words for pain or mistakes
The problem: I said 'ouch' when I dropped my pen and my friend laughed because I was not hurt.
You bump your knee on a table and say ouch. Ouch shows that something hurts. If you drop a pen without hurting yourself, oops marks the small mistake. You have other choices too: oh or ah might fit, based on how you feel and what you mean.
Use ouch when your body feels sharp hurt or heat.
Ouch! I stepped on a sharp pin.
Use oops when you slip or drop something by accident.
Oops, I typed the wrong number.
-
Ouch! That hot soup burned my lip.
Why it works: A burn is real body pain.
-
Oops, I gave you the wrong key.
Why it works: A wrong key is just a small error.
Your turn
Complete the sentence with oops or ouch.
Answer: Oops, I dropped my fork on the floor.
Show the answer
Answer: Oops
Of these two words, oops shows that you made a small mistake.
Tell relief apart from disgust
The problem: I want to recognize when phew expresses relief and when a reaction expresses disgust.
Ew often expresses disgust, such as a reaction to spoiled food. Phew often expresses relief after a worry ends. Phew has other uses too: it can react to a bad smell or to uncomfortable heat. Read the rest of the sentence and listen to the voice.
Use phew when you escape a difficult problem safely.
Phew, we didn't miss our flight.
Use ew when you see, touch, or smell something bad.
Ew, there's mud all over your coat.
Your turn
Which sentence clearly expresses relief that the food is still safe to eat?
Checking vegetables you feared had spoiled
Answer: Phew, the vegetables are still fresh.
Show the answer
Answer: Phew, the vegetables are still fresh.
Phew and still fresh show that the worry is over. Phew can also react to a bad smell in other contexts.
Match the tone to the situation
The problem: I used 'wow' and 'oops' in a formal (serious business) job email and my manager told me it looked unprofessional.
Reaction words are common in speech and friendly messages, even at work. If you need to say sorry to a client, state the problem and the next step clearly. Oops may make it sound less serious than you mean. Choose a tone that suits the person and the task.
This may fit a friendly chat, but could sound as though you do not care about the delay.
Oops, I missed the team deadline yesterday.
This clearly says that you are sorry for missing the deadline.
I apologize for missing yesterday's project deadline.
-
Yay, we've packed all the moving boxes!
Why it works: Great for celebrating with friends.
-
We're pleased to confirm that the project is complete.
Why it works: A more formal way to share the news when that tone suits the recipient.
Your turn
Which line gives a clear apology and a specific next step in this serious client email?
Writing to a new business client about a contract
Answer: We apologize for the delay and will send the contract by noon.
Show the answer
Answer: We apologize for the delay and will send the contract by noon.
The first choice says sorry and gives a clear time. Oops or uh-oh may sound as though you do not take the delay seriously.

What does an interjection do in a sentence?
An interjection expresses a reaction, such as surprise, pain, or pleasure. It can stand alone or come before or after the main sentence. When it accompanies a sentence, removing it often leaves the basic message intact while changing the speaker's reaction.
Wow, the tiny seed has grown into a tall plant!
Ouch! The zipper caught my skin.
Does an interjection always need an exclamation mark?
No. A comma can separate an interjection from the sentence that follows. An exclamation mark gives the reaction more emphasis and can let it stand on its own. The choice helps show the intended tone; the word oh, for instance, does not require the same punctuation every time.
Oh, the spare batteries are in the drawer.
Oh! There's a bird in the kitchen.
When should I use ouch instead of oops?
Use ouch to react to sudden pain. Use oops when you notice a small mistake or accident. Ouch can also be a humorous response to an unkind remark, so it is not limited to physical injury. Think about whether you are expressing hurt or acknowledging a slip.
Ouch! That thorn scratched my ankle.
Oops, I put the birthday card in the wrong envelope.
Does phew always express relief?
Phew often expresses relief after a worry or danger has passed. It can also show discomfort from heat or dislike of a smell. Ew expresses disgust. Because an interjection can have more than one use, listen to the situation and the rest of the sentence instead of assigning each sound just one feeling.
Phew, my wallet was in the inside pocket all along.
Phew! Open a window; that paint smells strong.
Ew, someone left wet socks on the dining table.
Can I use interjections in a work email?
Match the relationship and purpose of the email. A friendly message to a colleague may include wow or oops. In a serious apology, a clear explanation and next step usually fit better than a casual reaction. This is a choice about tone, not a rule that interjections are ungrammatical at work.
Wow, you finished the display before lunch!
I'm sorry I sent the earlier version; the corrected document is attached.
