Definition of Grammatical Errors
A grammatical error occurs when a sentence deviates from the established rules and conventions of English grammar. These errors can manifest in various forms, affecting different components of a sentence, such as subject-verb agreement, pronoun usage, verb tense, punctuation, and word choice.
Recognizing and correcting these errors is crucial for clear and effective communication.
Grammatical errors can obscure meaning, confuse the reader, and diminish the credibility of the writer or speaker. They often stem from a misunderstanding of grammatical rules or a lack of attention to detail.
By understanding the different types of grammatical errors and learning how to identify them, you can significantly improve the accuracy and clarity of your writing and speaking.
Structural Breakdown
Understanding the structure of a sentence is crucial for identifying grammatical errors. A typical English sentence follows a subject-verb-object (SVO) structure. The subject is the person, place, or thing performing the action. The verb expresses the action or state of being. The object receives the action. Modifiers, such as adjectives and adverbs, provide additional information about the subject, verb, or object.
Let’s break down this basic structure further. Each element plays a crucial role in the sentence.
The subject and verb must agree in number (singular or plural). Pronouns must agree with their antecedents in number and gender.
Verb tenses must be consistent and appropriate for the time frame being discussed. Modifiers must be placed correctly to avoid ambiguity.
Punctuation marks, such as commas, periods, and semicolons, must be used correctly to separate and connect clauses and phrases.
Types of Grammatical Errors
Grammatical errors can be categorized into several types, each with its own set of rules and common pitfalls. Understanding these categories will help you identify and correct errors more effectively.
Subject-Verb Agreement
Subject-verb agreement means that the verb in a sentence must agree in number (singular or plural) with its subject. Singular subjects take singular verbs, and plural subjects take plural verbs.
This is one of the most common sources of grammatical errors.
For example, “The dog barks” (singular subject, singular verb) is correct, while “The dog bark” is incorrect. Similarly, “The dogs bark” (plural subject, plural verb) is correct, while “The dogs barks” is incorrect.
Pronoun-Antecedent Agreement
A pronoun must agree in number, gender, and person with its antecedent (the noun or pronoun it refers to). This means that if the antecedent is singular, the pronoun must also be singular.
If the antecedent is plural, the pronoun must be plural. Similarly, the gender of the pronoun must match the gender of the antecedent.
For example, “John went to the store, and he bought milk” (singular antecedent, singular pronoun) is correct. “The students went to the library, and they studied” (plural antecedent, plural pronoun) is also correct. An error would be “Each student should bring *their* book,” which should be “Each student should bring *his or her* book” or, better, “All students should bring *their* books.”
Verb Tense Errors
Verb tense indicates when an action takes place. It’s important to use the correct verb tense to accurately convey the timing of events.
Common verb tenses include past, present, and future. Inconsistent or incorrect verb tense usage can confuse the reader.
For example, “I went to the store yesterday” (past tense) is correct. “I go to the store every day” (present tense) is also correct. However, “I went to the store tomorrow” is incorrect because it mixes past and future tenses. Maintaining consistency is key.
Misplaced Modifiers
A misplaced modifier is a word, phrase, or clause that is placed too far away from the word it modifies, causing confusion or unintended meaning. Modifiers should be placed as close as possible to the words they modify.
For example, “I saw a dog on the street with brown fur” is correct. However, “I saw a dog with brown fur on the street” is incorrect because it suggests that the street has brown fur. The modifier “on the street” should be closer to “I.”
Dangling Modifiers
A dangling modifier is a word, phrase, or clause that does not clearly modify any word in the sentence. This often happens when the subject of the modifying phrase is missing from the main clause.
For example, “After finishing the test, the students left the room” is correct. However, “After finishing the test, the room was empty” is incorrect because it suggests that the room finished the test. A better sentence would be “After the students finished the test, the room was empty.”
Comma Splices
A comma splice occurs when two independent clauses are joined together with only a comma. An independent clause is a group of words that can stand alone as a sentence.
Comma splices are considered grammatical errors because they fail to properly separate or connect the two clauses.
For example, “I went to the store, I bought milk” is a comma splice. It can be corrected by adding a conjunction: “I went to the store, and I bought milk.” Alternatively, you can use a semicolon: “I went to the store; I bought milk.” Or, you can create two separate sentences: “I went to the store. I bought milk.”
Run-on Sentences
A run-on sentence occurs when two or more independent clauses are joined together without any punctuation or conjunctions. Like comma splices, run-on sentences are considered grammatical errors because they fail to properly separate or connect the clauses.
For example, “I went to the store I bought milk” is a run-on sentence. It can be corrected by adding punctuation and/or conjunctions: “I went to the store, and I bought milk.” Or, “I went to the store; I bought milk.” Or, “I went to the store.
I bought milk.”
Fragments
A fragment is an incomplete sentence that lacks a subject, a verb, or both. Fragments often occur when a dependent clause is punctuated as a complete sentence.
For example, “Because I went to the store” is a fragment. It is a dependent clause that cannot stand alone as a sentence.
It can be corrected by adding an independent clause: “Because I went to the store, I bought milk.”
Article Errors
Articles (a, an, the) are used to specify whether a noun is definite (specific) or indefinite (unspecified). Using the wrong article can lead to confusion.
Use “a” before singular, countable nouns that begin with a consonant sound (e.g., “a dog,” “a car”). Use “an” before singular, countable nouns that begin with a vowel sound (e.g., “an apple,” “an hour”).
Use “the” before specific or previously mentioned nouns (e.g., “the dog,” “the car I bought”).
Preposition Errors
Prepositions are words that show the relationship between a noun or pronoun and other words in the sentence (e.g., “on,” “in,” “at,” “to,” “from”). Using the wrong preposition can change the meaning of the sentence.
For example, “I am going to the store” is correct, while “I am going at the store” is incorrect. The correct preposition depends on the specific context and the relationship you want to express.
Word Choice Errors
Word choice errors occur when the wrong word is used in a sentence, even if the sentence is grammatically correct otherwise. This can happen when words are similar in sound or spelling but have different meanings (e.g., “there,” “their,” and “they’re”).
For example, “I am going to the store” is correct, while “I am going too the store” is incorrect. While “too” is a valid word, it has a different meaning than “to.” Paying attention to the specific meaning of words is crucial for avoiding word choice errors.

Usage Rules
Understanding and applying usage rules is essential for accurate grammar. These rules govern how different parts of speech interact and how sentences are constructed.
While some rules are straightforward, others have exceptions and special cases. Paying close attention to these nuances will help you avoid common errors.
Subject-verb agreement requires the verb to match the subject in number. Singular subjects take singular verbs, and plural subjects take plural verbs. Collective nouns (e.g., team, family) can be singular or plural depending on whether they are acting as a unit or as individual members.
Pronoun-antecedent agreement requires the pronoun to match its antecedent in number, gender, and person. Indefinite pronouns (e.g., everyone, someone) are generally singular. When referring to a group of people, use plural pronouns. When gender is unknown, use “he or she” or rephrase the sentence to avoid the issue.
Verb tenses must be consistent within a sentence and paragraph. Use the appropriate tense to accurately convey the timing of events. Avoid unnecessary shifts in tense, which can confuse the reader. Use past perfect tense to describe an action that happened before another action in the past.
Modifiers should be placed as close as possible to the words they modify. Misplaced modifiers can create ambiguity and unintended meanings. Dangling modifiers do not clearly modify any word in the sentence and should be avoided.
Punctuation is crucial for clarity. Commas separate items in a list, introduce dependent clauses, and set off nonessential information. Semicolons connect related independent clauses. Colons introduce lists, explanations, or examples. Apostrophes indicate possession or contractions.
Common Mistakes
Even experienced writers make grammatical errors from time to time. Being aware of common mistakes can help you identify and correct them more effectively.
One common mistake is confusing “there,” “their,” and “they’re.” “There” indicates a place, “their” indicates possession, and “they’re” is a contraction of “they are.” Another common mistake is confusing “to,” “too,” and “two.” “To” indicates direction or purpose, “too” means also or excessively, and “two” is a number.
Subject-verb agreement errors are also common, especially with collective nouns and indefinite pronouns. Remember that collective nouns can be singular or plural depending on the context, and indefinite pronouns are generally singular.
Misplaced and dangling modifiers can create confusion and unintended meanings. Always place modifiers as close as possible to the words they modify, and ensure that dangling modifiers clearly modify a word in the sentence.
Comma splices and run-on sentences are also frequent errors. Remember to properly separate or connect independent clauses using conjunctions, semicolons, or separate sentences.
Below are some tables illustrating common mistakes:
| Incorrect | Correct | Explanation |
|---|---|---|
| Their going to the store. | They’re going to the store. | “They’re” is a contraction of “they are.” |
| There dog is barking. | Their dog is barking. | “Their” indicates possession. |
| The book is over their. | The book is over there. | “There” indicates a place. |
| I’m going to the store, to. | I’m going to the store, too. | “Too” means also. |
| I have to many books. | I have too many books. | “Too” means excessively. |
| I have to brothers. | I have two brothers. | “Two” is a number. |
| Incorrect | Correct | Explanation |
|---|---|---|
| Who’s car is that? | Whose car is that? | “Whose” indicates possession. |
| Your wrong about that. | You’re wrong about that. | “You’re” is a contraction of “you are.” |
| Its a beautiful day. | It’s a beautiful day. | “It’s” is a contraction of “it is.” |
| The effect of the storm was devastating. | The affect of the storm was devastating. | “Effect” is a noun, “affect” is a verb. |
| I except your apology. | I accept your apology. | “Accept” means to receive, “except” means to exclude. |

Advanced Topics
For advanced learners, mastering more complex grammatical concepts is essential for achieving a higher level of proficiency. These topics often involve subtle nuances and exceptions to general rules.
Subjunctive mood is used to express hypothetical situations, wishes, or commands. The subjunctive mood often uses the base form of the verb, regardless of the subject. For example, “I suggest that he be on time” (not “is”).
Conditional sentences express hypothetical situations and their consequences. There are several types of conditional sentences, each with its own verb tense patterns. For example, “If I had studied harder, I would have passed the exam” (third conditional).
Ellipsis is the omission of words that are understood from the context. Ellipsis can make sentences more concise and natural, but it should be used carefully to avoid ambiguity. For example, “I like coffee, and she does too” (omitting “like coffee”).
Inversion is the reversal of the normal word order in a sentence. Inversion is often used for emphasis or in questions. For example, “Never have I seen such a beautiful sight” (inversion for emphasis).
FAQ
- What is the most common type of grammatical error?
Subject-verb agreement is one of the most common grammatical errors, particularly when dealing with collective nouns or indefinite pronouns. Many people forget that collective nouns can act as singular or plural and that indefinite pronouns are generally singular.
- How can I improve my subject-verb agreement?
To improve subject-verb agreement, carefully identify the subject of the sentence and ensure that the verb agrees in number. Pay attention to collective nouns and indefinite pronouns, and be aware of intervening phrases that may separate the subject and verb.
- What is the difference between a comma splice and a run-on sentence?
A comma splice occurs when two independent clauses are joined together with only a comma. A run-on sentence occurs when two or more independent clauses are joined together without any punctuation or conjunctions. Both are grammatical errors that can be corrected by adding conjunctions, semicolons, or separate sentences.
- How can I avoid misplaced modifiers?
To avoid misplaced modifiers, place modifiers as close as possible to the words they modify. This will ensure that the modifier clearly refers to the intended word and avoids ambiguity or unintended meanings.
- What is a dangling modifier, and how can I fix it?
A dangling modifier is a word, phrase, or clause that does not clearly modify any word in the sentence. To fix a dangling modifier, revise the sentence so that the modifier clearly modifies a word in the sentence, or add the missing subject to the main clause.
- When should I use “a” versus “an”?
Use “a” before singular, countable nouns that begin with a consonant sound (e.g., “a dog,” “a car”). Use “an” before singular, countable nouns that begin with a vowel sound (e.g., “an apple,” “an hour”). Remember that it’s the sound, not the letter, that matters (e.g., “a university”).
- How can I improve my word choice?
To improve your word choice, read widely and pay attention to the specific meanings of words. Use a dictionary and thesaurus to find the most appropriate words for your intended meaning. Be aware of words that are similar in sound or spelling but have different meanings.
- Are there any tools that can help me identify grammatical errors?
Yes, there are many grammar-checking tools available online and in word processing software. These tools can help you identify and correct common grammatical errors, but they are not always perfect. It’s important to use your own judgment and knowledge of grammar to ensure that the corrections are accurate.
