Interjections
What is an Interjection?
An interjection is a word or short phrase that expresses a strong emotion or reaction. Interjections are one of the eight parts of speech in English (along with nouns, verbs, adjectives, adverbs, pronouns, prepositions, and conjunctions).
Interjections are special because they do not connect grammatically to the rest of the sentence. They stand alone and express feelings directly — like surprise, pain, joy, disgust, or hesitation.
| Definition An interjection is a word or phrase used to express emotion or reaction. It is usually placed at the beginning of a sentence and is followed by an exclamation mark (!) or a comma (,). |
Rules for Using Interjections
Rule 1: Strong Emotion — Use an Exclamation Mark (!)
When an interjection shows a very strong emotion, use an exclamation mark after it. The sentence that follows starts with a capital letter.
Wow! That is an amazing car.
Ouch! That really hurt!
Rule 2: Mild Emotion — Use a Comma (,)
When an interjection shows a softer, calmer reaction, use a comma. The sentence continues in lowercase.
Well, I think we should try again.
Oh, I didn’t know you were here.
Rule 3: Interjections Stand Alone Grammatically
Interjections do not change the grammar of the sentence. You can remove them, and the sentence will still be grammatically correct.
With interjection: Hey! Come here, please.
Without interjection: Come here, please.
Rule 4: They Can Be One Word or a Short Phrase
Interjections can be a single word or a small group of words.
One word: Great! Oh! Yes!
Short phrase: Oh no! Good grief! For goodness sake!
Types of Interjections
Interjections can be grouped by the type of emotion they express:
| Type of Emotion | Examples | Used When… |
| Surprise | Wow! Oh! Really? | Something unexpected happens |
| Pain | Ouch! Ow! | You feel physical or emotional pain |
| Joy / Excitement | Hooray! Yay! Yes! | You are happy about something |
| Disgust | Yuck! Ugh! Eww! | Something is unpleasant |
| Hesitation | Hmm… Uh… Er… | You are thinking or unsure |
| Greeting | Hey! Hi! Hello! | You greet or call someone |
| Silence | Shh! Hush! | You want someone to be quiet |
| Relief | Phew! Thank goodness! | You feel relieved after worry |

Common Mistakes to Avoid
- Do NOT use too many interjections in formal writing (emails, essays, reports). They are more common in spoken English and informal writing.
- Do NOT confuse interjections with other words. For example, ‘well’ can be a noun (a water well), an adjective (I feel well), or an interjection (Well, let me think…).
- Remember the punctuation rule: strong emotion = exclamation mark (!), mild emotion = comma (,).
Quick Practice
Read each sentence. Identify the interjection and the emotion it expresses.
| Sentence | Interjection | Emotion |
| Yay! I got the job! | ___________ | ___________ |
| Hmm… I don’t know the answer. | ___________ | ___________ |
| Ouch! That bee stung me. | ___________ | ___________ |
| Phew! We made it just in time. | ___________ | ___________ |
| Ugh! I missed the bus again. | ___________ | ___________ |
| Summary: Key Points • Interjections express emotions and reactions. • They do not connect grammatically to the rest of the sentence. • Strong emotion → exclamation mark (!); Mild emotion → comma (,). • They are more common in spoken and informal English. • Common examples: Wow!, Ouch!, Hooray!, Hmm…, Yuck!, Hey! |
