Subject-Verb Agreement: The Rules That Actually Matter
Most students know the basics — but the SAT tests the tricky cases. Learn the 4 patterns they keep reusing.
The SAT's Favorite Trick
The SAT never tests simple subject-verb agreement like "The dog runs." Instead, they bury the subject under prepositional phrases, relative clauses, or inverted sentence structures.
Pattern 1: The Prepositional Phrase Trap
"The collection of rare stamps is valuable."
"Stamps" is closer to the verb, but "collection" is the true subject. Ignore everything between the subject and verb.
Pattern 2: The Compound Subject
"Neither the teacher nor the students were prepared."
With "neither...nor" and "either...or," the verb agrees with the closer noun.
Pattern 3: Inverted Sentences
"Among the ruins stands a single column."
When a sentence starts with a prepositional phrase, find the real subject after the verb.
Pattern 4: Relative Clauses
"She is one of the students who have completed the project."
"Who" refers to "students" (plural), so the verb is plural.
The One Rule
When in doubt: cross out all the words between the subject and verb. Read the simplified sentence. The correct verb form becomes obvious.
