What is a modifier? A modifier (also known as a participle) is a descriptive word, phrase or clause that adds detail to the noun to which it’s attached. It describes the noun closest to it. Dangling modifiers — also called dangling participles — are descriptive words, phrases or clauses suffering from separation anxiety. We usually find them at the beginning of sentences. The modifiers are perfectly happy (and grammatically correct) when the thing they describe is planted right next to them. When that modified thing isn’t next to the descriptive phrase, the participle will clutch at and describe the closest noun, ultimately changing the meaning of your sentence.
Let’s look at a few examples:
Oh no! That poor dog! Because of the way this sentence is arranged, the modifier in the above sentence — “smashed flat by a passing truck” — describes the noun nearest it, which is the dog. That was not the author’s intent. Read the sentence below with the modifier describing the appropriate noun.
Example 1: Correct: The dog sniffed at what was left of a half-eaten hamburger that had been smashed flat by a passing truck.
Let’s try another one:
According to this example, your brother has been “rotting in the basement for a week.” No one wants a rotten brother anywhere near them, so we move the dangling modifier to correctly modify the appropriate subject.
Example 2: Correct: Your brother brought me an orange that had been rotting in the basement for a week.
Here’s a slightly more serious example and one that is more likely to occur in an office setting. A company policy reads:
Who is taking more than 3 consecutive sick days? This sentence says that “a signed doctor’s note” is taking more than 3 consecutive sick days. That is not the intended meaning. To revise, decide who actually will be taking off these days.
Example 3: Correct: If taking more than 3 consecutive sick days, an employee will need to provide a note from their doctor.
Dangling modifiers plague our emails, memos, letters, reports and policies, changing the meaning of them in unintended ways. When you know what to look for and be aware of, you too can avoid this common grammatical pitfall.
