To understand dangling participles, it is essential first to know what a participle phrase is.

A participle phrase is a group of words that contains a present participle (verb + -ing) or a past participle (second form of a verb). It functions as a modifier, providing additional information about another word or clause in the sentence.

• Carrying a heavy backpack, Maria entered the classroom.

In this sentence, the main clause is Maria entered the classroom, which can stand alone as a complete sentence. The phrase carrying a heavy backpack acts a modifier because it provides additional information about the subject, Maria. It explains what Maria was doing as she entered the classroom, giving more context and detail to the main clause.

Such a phrase which modifies (provide more information) about the main clause is called a participle phrase if it contains a present participle (e.g., 1st form of verb + ing) or a past participle (2nd form of a verb). For example, "carrying a heavy backpack" in the above example is a participle phrase as it contains 1st form of verb+ing (e.g. carrying).

A dangling participle is a participle phrase that does not clearly refer to the part of a sentence it is supposed to modify. This lack of clarity can confuse the reader, making it unclear which part of the sentence (e.g., a word or clause) is being modified. It is a writing mistake. Sometimes, a sentence may be structured in a way that causes a participle phrase to dangle between or among the parts of a sentence

 Example 1. Dangling Participle (with Present Participle).

• Flying in the sky, I saw a huge flock of birds.

In the above example, the participle phrase flying in the sky is a dangling participle. It confuses the reader because it is unclear whether the speaker or the flock of birds was flying when the speaker saw the birds. Using common sense, we understand that the flock of birds was flying. However, the way the sentence is written suggests the opposite: that the speaker was flying. This happens because a modifier generally modifies the word nearest to it. Since the subject 'I' comes immediately after the participle phrase, it appears that 'I' am being modified rather than the 'flock of birds'.

Using common sense helps interpret the intended meaning, but structurally, the sentence is incorrect. This is a simple example to illustrate the issue, but in more complex sentences, dangling participles can make the meaning very confusing.

A dangling participle is a common writing mistake which is corrected by restructuring the sentence or adding a few words to the sentence. For instance, the above sentence can be corrected as follows:

• I saw a huge flock of birds flying in the sky.

 Example 2. Dangling Participle (with Present Participle).

• Answering all the questions correctly, the interviewer selected him for the job.

Here, the participle phrase answering all the questions correctly is dangling. It is unclear whether it refers to the interviewer or the person being interviewed. Using common sense, we know that the person answered the questions correctly. The confusion arises because the word interviewer follows the participle phrase.

Corrected versions:

• Answering the questions correctly, he was selected for the job by the interviewer.
• The interviewer selected him for the job because he had answered the questions correctly.

 Example 3. Dangling Participle (with Past participle)

• Injured in a car accident, we took the man to a hospital.

The phrase ‘injured in a car accident’ is a dangling participle having past participle (injured). It dangles between the subject ‘we’ and the object ‘man’. It confuses the reader to think whether the ‘we’ were injured in the car accident or the ‘man’ was injured in the car accident when we took him to a hospital. This is because the way the sentence is written gives meaning different from its intended meaning. This sentence can be corrected in the following two ways:

• Injured in a car accident, the man was taken to a hospital by us.
• We took the man to a hospital who was injured in a car accident.

Sentences with dangling participles can be corrected by:

• Re-structuring the sentence
• Adding a few missing words
• Changing the voice (active ↔ passive)

First, identify the target word (noun or pronoun) that is likely being modified, then restructure the sentence accordingly.

 Example 1.

• Talking funny, people were laughing at the joker. (wrong).
• People were laughing at the joker who was talking funny. (correct).

Here, the correction is done by re-arranging words and adding a few words.

 Example 2.

• Crying out of pain, the doctor encouraged the patient. (wrong).
• The doctor encouraged the patient who was crying out of pain. (correct).

It can be seen in the above example that the correction is made simply by re-arranging the words of the sentence and adding a few words to it.

 Example 3.

• Already worried about her result, the news of her failure in the exam saddened her further. (wrong).
• Already worried about her result, she was saddened further by the news of her failure in the exam. (correct).
• The news of her failure in the exam saddened her further who was already worried about her results. (correct).

It can be seen in the above correction, the first correction has been made by converting the second part of sentence from active voice to passive voice. The second correction has been made by re-arranging the words of sentence and adding a few words to it to clarify the meaning.

 Example 4.

• Tired of whole day work, watching a movie relaxed me. (wrong).
• Tired of whole day work, I was relaxed by watching a movie. (correct).

Note.  Some dangling phrases do not have a participle in them. Such a phrase cannot be called a dangling participle. Such a phrase is simply called a dangling modifier. Read the following example.

• At the age of sixteen, my father gifted me a bicycle. (Wrong).
• At the age of sixteen, I was gifted a bicycle by my father. (Correct).
