Subject-Verb Agreement Exercises: 30 Sentences That Trick Everyone

Subject-verb agreement has one core rule: the verb agrees with the true grammatical subject in number, not with the noun that happens to sit closest to it. The traps all work the same way — they insert a plural-looking word between the real subject and the verb (each of the students has, one of my friends lives, the number of accidents has fallen), or they use subjects whose number is not what it looks like (news, mathematics, ten dollars, everybody).

The 30 sentences below are sorted from warm-up to challenge and are the exact patterns that trip native speakers as often as learners. Every answer is checked on the spot with a one-line explanation, so each miss teaches you the rule instead of just the answer.

The One Rule Behind Every Agreement Question

Every subject-verb agreement question reduces to a single move: find the true grammatical subject, ignore everything between it and the verb, and match the verb to it. The traps are not different rules — they are all distractions placed between the subject and the verb, counting on your eye to grab the nearest noun instead.

Words That Look Plural but Take a Singular Verb

English has a shelf of nouns and pronouns whose number is not what it looks like. The -s on news, mathematics, physics, and economics is historical, not plural. Indefinite pronouns ending in -body, -one, and -thing are grammatically singular even though they refer to many people. And quantities — ten kilometers, ten dollars, three hours — describe one unit when the amount is treated as a block.

Either/Or and Neither/Nor: The Verb Follows the Nearest Subject

When two subjects are joined by or, nor, either…or, or neither…nor, the verb agrees with the one closer to it. Neither the manager nor the employees are… but neither the employees nor the manager is…. The sentence can be grammatically correct with either a singular or a plural verb — the nouns decide, not the logic.

A practical writing tip follows directly: put the plural noun second when you want the smoother plural verb, and never mix in along with or as well as expecting the same effect — those phrases do not create a compound subject, and the verb stays with the first noun.

A Number of vs. The Number of — and Other Amount Traps

The famous pair works like this: a number of means several and behaves like a plural (a number of students are waiting), while the number of names the count itself and is singular (the number of students has doubled). The same logic extends to fractions and percentages, which copy the noun they modify: half of the pizza is, half of the students are, two-thirds of the vote has been counted, two-thirds of the voters have been counted.

Collective nouns — team, committee, staff, family — are the grey zone: American English usually treats them as singular (the team is winning), while British English allows plural when the members act individually. In international and exam writing, the singular is the safe default, and the plural is reserved for cases where division is the point (the committee are divided).

Why Everyone Gets Agreement Wrong — Proximity Beats Logic

Psychologists call the core error proximity attraction: as you build a sentence, the plural noun sitting just before the verb hijacks the verb form, even though your grammar system knows the real subject is singular. That is why each of the answers are feels right in the moment and wrong on rereading — attraction happens in real time, and the check happens later (if at all). Native speakers make these errors in unedited writing at nearly the same rate as advanced learners.

The second source is your first language. If your language marks agreement on the verb weakly or not at all — Chinese, Japanese, Indonesian, Thai — there is no habit to transfer, and every English verb needs a conscious number decision. If your language marks number differently (Spanish and Arabic pluralize differently after each/none-type words), your instinct actively votes for the wrong form: each of the students have is a direct translation of a correct sentence in Spanish. Either way, the fix is the same: train the find-the-subject move until it outruns both proximity and translation.

How to Practice Agreement So It Becomes Automatic

Agreement is a spotting skill before it is a choosing skill, so practice both: one 30-question set per day for a week (every answer above is checked instantly, with the rule named), and then the scan-and-check habit on your own drafts.

For the second part, paste a recent email, essay, or report into PromGee’s free grammar checker. It flags every agreement decision, shows the true subject it found, and explains the rule — so your own sentences become the next exercise set.
