Contractions in English: Don’t, Won’t, I’m and More
Quick Answer
A contraction joins two words into one shorter word with an apostrophe: do not → don’t, I am → I’m. The apostrophe (‘) stands exactly where the missing letters used to be.
Contractions You Hear Every Day
Native speakers use contractions in almost every sentence. Look how they are built:
- I am tired. → I’m tired. (The apostrophe replaces the a.)
- She is here. → She’s here. (The apostrophe replaces the i.)
- We do not know. → We don’t know. (The apostrophe replaces the o.)
- They have finished. → They‘ve finished. (The apostrophe replaces ha.)
Did you see the pattern? Two words become one, and the apostrophe marks the exact spot where letters disappeared.
| Full form | Contraction | Full form | Contraction |
|---|---|---|---|
| I am | I’m | do not | don’t |
| you are | you’re | cannot | can’t |
| he is / he has | he’s | will not | won’t |
| it is / it has | it’s | is not | isn’t |
| they are | they’re | should not | shouldn’t |
| we have | we’ve | would not | wouldn’t |
The Rules — and the One Rebel: Won’t
Most contractions follow one simple rule, but one famous word breaks it:
- Normal rule: keep the words, drop some letters, add an apostrophe. → is not → isn’t.
- The rebel: will not → won’t (not “willn’t”!). It comes from the old English form wonnot.
- Use them in speech, messages, and friendly emails. In very formal writing (contracts, academic essays), write the full forms.
Easy way to remember: the apostrophe stands exactly where the missing letters used to be: do not → don’t.
The Rule in One Line: A contraction = two words joined into one; the apostrophe marks the missing letters.
How to Use Contractions in Everyday English
- “I’m on my way — don’t start without me!” (Two contractions in one message.)
- “She can’t come tonight; she‘s working late.” (cannot / she is.)
- “We’ve been friends for ten years.” (we have.)
- “He won’t answer his phone.” (will not.)
- “It’s raining again.” (it is.)
You are doing great. Now let’s look at the mistakes many learners make.
The Two Contraction Mistakes Everyone Makes
These two mix-ups are so common that native speakers make them daily on social media — you are in good company.
✗ “Its raining outside.” (its = possession, no apostrophe)
✓ “It’s raining outside.” (it’s = it is)
✗ “Your welcome!” (your = belonging to you)
✓ “You’re welcome!” (you’re = you are)
How to remember: say the full form out loud. If “it is” or “you are” fits, use the apostrophe: it’s, you’re. If not, no apostrophe.
