Two kinds of modifier errors
| Error | Wrong | Right | Why |
|---|---|---|---|
| Dangling: the doer is missing | Walking to school, the rain started. | Walking to school, I got caught in the rain. | The opening phrase describes whatever comes right after the comma. Rain cannot walk. |
| Dangling with a possessive | Running for the bus, Jamal's phone fell. | Running for the bus, Jamal dropped his phone. | The subject is phone, not Jamal. The phone was not running. |
| Misplaced phrase | I found a gold ring walking on the beach. | Walking on the beach, I found a gold ring. | The phrase sat next to ring. Move it next to I. |
| Misplaced describing words | The store sold sweaters to customers made of wool. | The store sold wool sweaters to customers. | The customers are not made of wool. |
The two fixes for a dangling modifier
- Name the doer right after the comma: After finishing the test, I felt relieved.
- Put the doer inside the opening phrase: After I finished the test, the room felt quieter.
Worked examples
Example 1: a dangling opener
Problem After finishing the test, the room felt quieter.
- Who finished the test? The sentence never says. The room comes after the comma, and rooms do not take tests.
- Fix by putting the doer in the opening phrase, since the main idea is about the room.
Answer After I finished the test, the room felt quieter.
Example 2: a phrase in the wrong place
Problem We saw a deer driving home from practice.
- Driving home from practice sits next to deer, so it sounds like the deer was driving.
- Move the phrase to the front so it sits next to we.
Answer Driving home from practice, we saw a deer.
Example 3: a to phrase
Problem To win the science fair, the poster needs bright colors.
- Who wants to win? A student, not the poster.
- Name the student right after the comma.
Answer To win the science fair, you need a poster with bright colors.
Common mistakes and fixes
| Mistake | Fix |
|---|---|
| Thinking a possessive (Jamal's phone) names the doer | The subject is the thing owned. Rewrite so the person is the subject. |
| Fixing a dangler by moving the comma | Commas do not fix it. Change the subject or the opening phrase. |
| Using passive voice after an opener (the comet was noticed by) | Make the doer the subject: the astronomer noticed the comet. |
| Leaving a describing phrase at the end of a long sentence | Put it right next to the noun it describes. |

Five modifier questions
Which sentence is correct?
- Running to catch the bus, the phone fell out of Jamal's pocket.
- Running to catch the bus, Jamal's phone dropped.
- Running to catch the bus, Jamal dropped his phone.
- Running to catch the bus, the phone was dropped by Jamal.
Show answer
Answer: Running to catch the bus, Jamal dropped his phone.
The person running is Jamal, so Jamal must come right after the comma. In the other choices the first noun after the comma is the phone or Jamal's phone, which says the phone was running.
Which sentence is clearest?
- I found a gold ring walking on the beach.
- I found walking on the beach a gold ring.
- Walking on the beach, I found a gold ring.
- A gold ring, walking on the beach, I found.
Show answer
Answer: Walking on the beach, I found a gold ring.
The phrase describes the person walking, so it must sit next to I. The other choices place it next to ring or split the sentence awkwardly.
Which revision fixes this sentence? After finishing the test, the room felt quieter.
- After finishing the test, the room was quieter.
- After I finished the test, the room felt quieter.
- After finishing, the test made the room quieter.
- The room felt quieter, after finishing the test.
Show answer
Answer: After I finished the test, the room felt quieter.
Adding I inside the opening phrase names who finished. The other choices still have no person doing the finishing, so the room or the test seems to be finishing.
Which revision fixes this sentence? The store sold sweaters to customers made of wool.
- The store sold sweaters to wool customers.
- The store, made of wool, sold sweaters to customers.
- Made of wool, the store sold sweaters to customers.
- The store sold sweaters made of wool to customers.
Show answer
Answer: The store sold sweaters made of wool to customers.
Made of wool describes the sweaters, so it must sit next to sweaters. The other choices attach it to the store or the customers.
Which sentence has a dangling modifier?
- To win the science fair, you need a clear question.
- To win the science fair, the poster needs bright colors.
- Excited about the trip, Marco packed the night before.
- Covered in mud, the dog ran into the kitchen.
Show answer
Answer: To win the science fair, the poster needs bright colors.
The poster is not trying to win. In the other sentences, the first noun after the comma is the one doing or being described: you want to win, Marco is excited, the dog is muddy.
Frequently asked questions
What is the difference between a misplaced and a dangling modifier?
A misplaced modifier has the right noun in the sentence, just in the wrong spot, so you fix it by moving the phrase. A dangling modifier has no noun for it to describe at all, so you fix it by adding the doer, either after the comma or inside the opening phrase.
Are dangling modifiers on the SAT?
Yes. College Board lists subject-modifier placement in the Form, Structure, and Sense skill, and its own sample question tests a dangling modifier. The usual setup is an opening phrase followed by a blank. See SAT Form, Structure, and Sense.
Is a dangling modifier always confusing?
Not always. Readers can often guess the meaning, which is why these errors slip into writing. But formal writing and tests treat them as errors, and some create funny or wrong meanings. Fixing them takes one small change and makes the sentence clearer.
