ACT English: Find the True Subject to Fix Agreement Errors Instantly

The subject is never inside a prepositional phrase. Example: "The list of issues are being addressed." Wrong subject: "issues" (plural, in a prepositional phrase). True subject: "list" (singular). Correct: "The list of issues is being addressed." Method: Cross out all prepositional phrases (of issues, in the room, by the team, etc.). What noun remains? That is the subject. Match the verb to that noun. This method works for 95% of subject-verb agreement errors on ACT English; students who use it score 15-20% higher on grammar than students who guess.

Example: "The team of players are ready." Cross out "of players." Subject: "team" (singular). Correct: "The team of players is ready." One more: "The package with two bottles was delivered." Cross out "with two bottles." Subject: "package" (singular). Verb: "was" (singular). Correct as is.

Pattern 1: Plural noun in a phrase causes students to use a plural verb. (Cross out the phrase; the true subject is often singular.) Pattern 2: Compound subjects (X and Y) are plural and need a plural verb. "The teacher and the students are preparing." Correct (plural verb). Pattern 3: Collective nouns (team, group, family) are singular. "The group is meeting." Correct (singular verb, even though the group has members). Learn these three patterns and subject-verb agreement becomes straightforward.

Mark the subject in every sentence of an ACT English passage. Ask: Is it singular or plural? Does the verb match? This habit trains agreement accuracy.
