The headline of this post is an example of a misplaced modifier (more specifically, this one is a dangling participle). Misplaced modifiers pop up every day, and even though it’s often clear what the writer meant, they cause a little stumble — and occasionally major confusion — for the reader.
Why it’s wrong: When you “back into” a sentence with a phrase, the information in that phrase goes with the subject of the sentence. So here, the “having started this post” goes with “an idea,” which is not right — it belongs with “me.” Sometimes sentences start with a phrase that doesn’t belong with anything in the sentence, which can really confuse readers.
How to spot one: Anytime you have a sentence that begins with a phrase — an adjective phrase, a prepositional phrase, a participial phrase — make sure that phrase goes with the subject.
How to fix it: You may be able to simply move the modifying phrase closer to what it modifies, or you may need to rewrite the sentence. With a dangling participle, it’s often better to change the participial phrase to a subordinate clause, which is what works for the title of this post: “As I started this post, an idea struck me.”
Here are a couple more examples:
This is not a post about immigration — grammarians have no power over politics. It is a post about some of the more complicated aspects of subject-verb agreement, and it’s something I hope everyone can agree on.
The basics: Subjects and verbs must agree, that is, singular subjects get singular verbs, and plural subjects get plural verbs. With straight subject-verb-object constructions, this is easy and everyone gets it right.
A wrinkle: When more elements — such as a prepositional phrase or subordinate clause — are added to a sentence, it can end up that a plural noun is right before the verb, but is not the subject of the verb. Only the subject gets to “govern” the verb, that is, determine its number.
Example: The headline pictured above, “Flood of unaccompanied minors rush to cross Southwest border.”
To check agreement, take out the phrase or clause temporarily and look at the sentence. With no intervening words, it will be obvious what the verb needs to be.
of unaccompanied minors rush to cross Southwest border.” “Flood” is singular, so the verb should be “rushes.”
And the really tricky type: “She is one of those annoying people who publicly correct/corrects other people’s grammar.”
Should the verb be singular or plural? Let’s examine this sentence closely to find out.
- “She” is not the subject of the verb “correct” – “she” is the subject of the verb “is.”
- The subject of the verb “correct” is the relative pronoun “who,” which is referring to “people,” which is plural.
- So “correct” is correct.
Think of it this way: There are annoying people who publicly correct other people’s grammar. She is one of them.
Thus, “She is one of those annoying people who publicly correct other people’s grammar.” But if someone says “corrects,” don’t correct them — it’s a common mistake and not one that sticks out.
