Allow vs "Is Allowed"- Correct Grammar Usage
Allow vs "Is Allowed" — The Grammar You Actually Need to Know
Most people get this wrong, or at least get confused by it. Here's the deal.
The Basic Difference
Allow is what someone with authority does. Is Allowed is what happens when that authority says yes.
Simple example:
- The teacher allows students to use calculators. (Active — the teacher is doing the allowing)
- Students are allowed to use calculators. (Passive — the permission exists, but who's doing it? Doesn't matter)
Both are correct. The choice depends on what you want to emphasize.
When to Use Each
Use allow when you want to mention the person giving permission:
- The manager allows late submissions.
- My contract allows me to work remotely.
Use is allowed (or "are allowed") when the focus is on the permission itself, not who gave it:
- Late submissions are allowed on Fridays only.
- Remote work is allowed with supervisor approval.
Common Mistakes
People mess this up in two ways:
1. Using "allow" when they mean "is allowed"
❌ "The parking lot allow only residents."
✅ "The parking lot allows only residents."
✅ "Parking is allowed only for residents."
2. Confusing "allow" with "can"
These mean different things:
- "You are allowed to park here" = permission was granted
- "You can park here" = you have the ability or it's possible
Don't swap them unless you mean the same thing.
Quick Reference Table
| Sentence | Correct? | Why |
|---|---|---|
| Smoking allows here. | ❌ No | Wrong structure |
| Smoking is allowed here. | ✅ Yes | Passive voice, correct |
| We allow pets in the lobby. | ✅ Yes | Active voice, subject does the allowing |
| Pets are allowed in the lobby. | ✅ Yes | Passive voice, correct |
| Does this allow me to leave early? | ✅ Yes | Question form of "allow" |
The Rule to Remember
If you can answer "who is doing the allowing?" then use allow. If the answer is "it doesn't matter" or "the rule itself," use is allowed.
That's it. No need to overthink this.
