Understanding Subject-Verb Agreement in English Grammar
Subject-verb agreement is a cornerstone of English grammar that ensures your sentences are grammatically correct and easy to read. This fundamental rule requires that the verb agrees with its subject in terms of number and person. A singular subject like ‘the dog’ demands a singular verb like ‘barks’, while ‘dogs’ needs ‘bark’. Mastering this concept can transform your writing from basic to sophisticated. In this comprehensive guide, we will cover the main rules, common mistakes, and practical exercises to help you achieve fluency in subject-verb agreement. Whether you are a beginner or looking to refine your skills, this blog post is designed to provide clear, concrete insights with real-life examples and tips.
Why should you care about subject-verb agreement? In an age where writing is everywhere—from business proposals to social media posts—clarity is paramount. Errors in agreement can confuse readers, making your message less effective. For instance, a manager writing to a team might write ‘The team is deciding’ when they mean multiple decisions, leading to miscommunication. Correct usage ensures your writing is professional and impactful.
This article aims to demystify these rules by breaking them down into digestible sections. We will start with basics, move to tricky cases like collectives and pronouns, highlight frequent errors with examples, offer exercises, and conclude with advanced advice. By investing time in learning these fundamentals, you will notice a marked improvement in your grammar skills and overall writing quality.
Basic Rules of Subject-Verb Agreement
Rule 1: The Subject Determines the Verb Form
The primary rule is simple yet powerful. The subject, which is the person or thing performing the action, dictates the form of the verb. Take the sentence ‘The sun rises in the east.’ ‘Sun’ is singular, hence ‘rises’. Pluralize to ‘The suns rise’ to match. Example: ‘Every morning, the birds sing.’ ‘Birds’ plural ‘sing’. To apply this, always identify the true subject. In ‘The key to success is hard work.’, ‘key’ is singular, verb ‘is’. In ‘Keys to success are…’, plural.
Expand this with more examples. Suppose ‘The amount of money increases with inflation.’ ‘Amount’ singular. ‘The amounts increase.’ Plural. ‘A large number of students are attending.’ ‘A large number’ is plural because of the following plural noun.
Rule 2: Prepositional Phrases Do Not Affect Agreement
Here is where many go wrong. Phrases introduced by prepositions are usually not part of the subject. ‘The pile of books on the table is heavy.’ The subject is ‘pile’, singular, verb ‘is’. Even if there are many books, the verb stays singular. This prevents overcomplication. Let’s consider another layer: when the prepositional phrase is long and complicated. ‘The large collection of rare books in the library was donated by a famous collector.’ The subject is ‘collection’, singular, verb ‘was’. This complexity is common in descriptive writing and requires extra care to avoid errors. Writers should break down complex sentences to pinpoint the subject accurately. Another example: ‘The box of candies were delicious.’ Wrong; it should be ‘is’ because ‘box’ is the subject. Practice this by circling the prepositional phrase: The [prepositional phrase] [verb]. It helps you see the true subject.
Rule 3: Agreement with Subjects Joined by and or or
When subjects are joined by ‘and’, the verb is usually plural. ‘The boy and the girl are playing.’ Plural subjects, plural verb. If the subjects are the same person, singular usage may apply in idiomatic cases like ‘Bread and butter is my favorite breakfast.’ But standard is plural if different: ‘The doctor and the nurse are colleagues.’ For ‘or’, verb agrees with the nearer subject: ‘The teacher or the students are going.’ Correction depends on proximity to nearest.
Advanced Topics in Subject-Verb Agreement
Collective Nouns and Their Agreement
Collective nouns can be a source of confusion. Words like ‘team’, ‘group’, ‘family’, ‘committee’, ‘army’, ‘audience’. In American English, they are often treated as singular: ‘The team is practicing.’ If you want to stress individuals, you can use plural verbs or rephrase: ‘The members of the team are practicing.’ This flexibility allows writers to convey nuanced meanings. British English sometimes uses plural more often: ‘The team are playing well.’ To decide, ask if you mean the whole or parts. Historical note: These rules stem from Latin influences on English grammar. Over centuries, the language evolved to include these nuances.
Indefinite Pronouns
Indefinite pronouns are always singular: anyone, someone, everyone, no one, each, either, neither. ‘Anyone can do it.’ Verb ‘can’ singular. ‘Neither option is available.’ ‘Is’ singular. ‘Each person has their own responsibility.’ Modern usage accepts ‘their’ for singular. ‘One of the reasons is that…’ ‘One’ singular.
Common Grammar Mistakes in Subject-Verb Agreement
Let’s review ten frequent mistakes with detailed corrections and examples:
- Mistake 1: Mismatching with plural subjects. Wrong: ‘The cats is sleeping.’ Correct: ‘The cats are sleeping.’
- Mistake 2: Prepositional interference. Wrong: ‘A lot of water are needed.’ Correct: ‘A lot of water is needed.’ (standard is singular here for uncountable)
- Mistake 3: Collective nouns. Wrong: ‘The government are divided.’ Correct: ‘The government is divided.’
- Mistake 4: With ‘neither…nor’. Wrong: ‘Neither the students nor the teacher were absent.’ Correct: ‘Neither the student nor the teacher was absent.’
- Mistake 5: Indefinite. Wrong: ‘Each of the students have a book.’ Correct: ‘Each of the students has a book.’
- Mistake 6: Subjects with ‘as well as’. Wrong: ‘The chef as well as the assistants are leaving.’ Correct: ‘The chef as well as the assistants is leaving.’
- Mistake 7: When subjects are the same. Wrong: ‘The president and CEO is the same person.’ Correct: ‘The president and CEO are the same person.’ If referring to one person, singular ‘The president and CEO is one and the same.’
- Mistake 8: With numbers or measurements. Wrong: ‘Ten dollars is a lot of money.’ Correct: ‘Ten dollars are a lot…’ (often plural in some styles)
- Mistake 9: Foreign nouns. Wrong: ‘The phenomenon are rare.’ Correct: ‘The phenomenon is rare.’
- Mistake 10: With ‘data’. Wrong: ‘The data was collected.’ Correct: ‘The data were collected.’ (data can be plural)
These mistakes are common because they require careful attention to the actual subject. To fix them, rewrite the sentence to identify the subject clearly.
Practical Exercises for Skill Development
Apply what you’ve learned with these exercises. For each, identify the subject and determine the correct verb:
- Exercise 1: Correct the agreement: ‘The committee and the board was meeting today.’
- Exercise 2: Write a sentence using an indefinite pronoun and a matching verb.
- Exercise 3: Fix: ‘The boxes of toys are too heavy for the child.’
- Exercise 4: Advanced: ‘Either the manager or the employees is coming to the meeting.’
- Exercise 5: Correct: ‘The news of the victory was exciting.’
- Exercise 6: Practice: ‘A pair of shoes is on the table.’ Is ‘pair’ singular or plural? Discuss in your writing.
For each exercise, write your answer and explain why. Then, compare to standard grammar references. Do this daily for a week to see improvement.
Best Practices and Final Tips
Read your writing aloud to catch agreement errors. They often sound wrong when spoken. Use grammar checkers like Grammarly to flag issues, but always verify manually. Writing regularly—journals, blogs, emails—helps reinforce the rules. Consult style guides like The Chicago Manual of Style for specific rules on data or collective nouns.
