Definition of Common Writing Mistakes

Common writing mistakes are errors in grammar, punctuation, word choice, or sentence structure that frequently occur in written English. These mistakes can detract from clarity, credibility, and the overall effectiveness of communication.

Recognizing and correcting these errors is a crucial step in improving your writing skills. They often stem from a misunderstanding of grammatical rules, carelessness, or simply a lack of awareness.

These errors can be classified into several categories, including:

• Grammatical errors: Mistakes in subject-verb agreement, pronoun usage, tense consistency, etc.
• Punctuation errors: Incorrect use of commas, apostrophes, semicolons, etc.
• Word choice errors: Using the wrong word (e.g., “affect” instead of “effect”) or using words inappropriately.
• Sentence structure errors: Problems with sentence fragments, run-on sentences, misplaced modifiers, etc.

Subject-Verb Agreement

Subject-verb agreement means that the verb in a sentence must agree in number (singular or plural) with its subject. This is a fundamental aspect of grammatical correctness.

Singular subjects take singular verbs, and plural subjects take plural verbs. Identifying the true subject of a sentence is crucial, especially when there are intervening phrases or clauses.

Basic Rule: Singular subject + singular verb; Plural subject + plural verb.

Examples of Subject-Verb Agreement

The following table provides examples of correct and incorrect subject-verb agreement. Notice how the verb changes based on whether the subject is singular or plural.

Pay close attention to compound subjects and collective nouns.

Pronoun Agreement

Pronoun agreement requires that a pronoun agrees in number (singular or plural), gender (masculine, feminine, or neuter), and person (first, second, or third) with its antecedent (the noun or pronoun to which it refers). This ensures clarity and avoids confusion in writing.

Basic Rule: A pronoun must agree with its antecedent in number, gender, and person.

Examples of Pronoun Agreement

The following table illustrates correct and incorrect pronoun agreement. Note how the pronoun changes to match the antecedent in number and gender.

Indefinite pronouns and collective nouns often require special attention.

Incorrect Tense Usage

Correct tense usage is crucial for conveying the timing and sequence of events accurately. Using the wrong tense can confuse the reader and alter the intended meaning.

Consistency in tense within a sentence and paragraph is essential, unless there is a clear reason to shift tenses.

Basic Rule: Use the correct tense to indicate when an action occurred or will occur, and maintain consistency unless a change in time frame is necessary.

Examples of Incorrect Tense Usage

The following table provides examples of correct and incorrect tense usage. Pay attention to the context and how the tense of the verb affects the meaning of the sentence.

Consistent tense usage is key to clear writing.

Misplaced Modifiers

A misplaced modifier is a word, phrase, or clause that is placed too far from the word it is intended to modify, causing confusion or unintended meanings. Modifiers should be placed as close as possible to the words they describe.

Correcting misplaced modifiers improves clarity and prevents misinterpretation.

Basic Rule: Place modifiers as close as possible to the words they modify.

Examples of Misplaced Modifiers

The following table provides examples of sentences with misplaced modifiers and their corrected versions. Notice how moving the modifier closer to the intended word clarifies the meaning.

Dangling Modifiers

A dangling modifier is a word, phrase, or clause that does not clearly or logically modify any word in the sentence. Unlike a misplaced modifier, a dangling modifier cannot be corrected simply by moving it; the sentence structure must be revised to include a clear subject for the modifier to describe.

Basic Rule: Ensure that the modifier clearly and logically refers to the subject of the sentence.

Examples of Dangling Modifiers

The following table provides examples of sentences with dangling modifiers and their corrected versions. Notice how the corrected sentences add or revise the main clause to provide a clear subject for the modifier.

Comma Splices

A comma splice occurs when two independent clauses (clauses that can stand alone as sentences) are joined together with only a comma. This is a common error that can be corrected by using a semicolon, a conjunction, or by separating the clauses into two distinct sentences.

Basic Rule: Do not join two independent clauses with only a comma. Use a semicolon, a coordinating conjunction, or separate them into two sentences.

Examples of Comma Splices and Corrections

The following table provides examples of comma splices and the different ways they can be corrected. Understanding these corrections is crucial for avoiding this common writing error.

Comma Splice	Corrected with Semicolon	Corrected with Conjunction	Corrected as Two Sentences

Run-On Sentences

A run-on sentence occurs when two or more independent clauses are not properly connected. Unlike a comma splice, a run-on sentence may lack any punctuation or connecting words altogether.

Correcting run-on sentences involves separating the clauses into distinct sentences, using appropriate punctuation, or adding conjunctions.

Basic Rule: Ensure that independent clauses are properly connected with appropriate punctuation or conjunctions, or separate them into distinct sentences.

Examples of Run-On Sentences and Corrections

Sentence Fragments

A sentence fragment is a group of words that is punctuated as a sentence but does not express a complete thought. It may lack a subject, a verb, or both, or it may be a dependent clause standing alone.

Correcting sentence fragments involves adding the missing elements or combining the fragment with a related independent clause.

Basic Rule: Ensure that every sentence has a subject and a verb and expresses a complete thought. Avoid punctuating incomplete thoughts as sentences.

Examples of Sentence Fragments and Corrections

The following table provides examples of sentence fragments and the ways they can be corrected. Recognizing and correcting fragments is crucial for clear and coherent writing.

Basic Rules:

• Use apostrophes to show possession (e.g., John’s car).
• Use apostrophes in contractions to indicate missing letters (e.g., can’t).
• Avoid using apostrophes to form plurals (except for single letters or abbreviations for clarity).

Definitions:

• Affect: Primarily a verb meaning “to influence” or “to produce a change in” (e.g., “The weather affects my mood.”).

“Lie” and “lay” are often confused because they are related to the act of reclining or placing something down, but they have different forms and usages.

Definitions:

• Lie: Intransitive verb meaning “to recline” or “to be in a horizontal position.” It does not take a direct object (e.g., “I lie down to rest.”). Principal parts: lie, lay, lain, lying.

Common Mistakes

Beyond the specific errors detailed above, there are several other common writing mistakes that can detract from the clarity and effectiveness of your writing. These include issues with wordiness, jargon, clichés, and inconsistencies in style and tone.

Wordiness

Wordiness refers to using more words than necessary to express an idea. Concise writing is generally more effective and easier to understand.

Avoid unnecessary phrases and redundant expressions.

Example:

Jargon

Jargon is specialized language used by a particular group or profession. While it can be useful for communicating with others in the same field, it can be confusing or alienating to a general audience.

Avoid using jargon unless you are certain that your readers will understand it.

Example:

Clichés

Clichés are overused expressions that have lost their impact and originality. While they may be familiar and easy to use, they can make your writing seem uninspired and unoriginal.

Try to find fresh and creative ways to express your ideas.

Example:

Inconsistencies in Style and Tone

Maintaining a consistent style and tone throughout your writing is important for creating a cohesive and professional impression. Avoid abrupt shifts in formality, voice, or point of view.

Mastering these devices can add depth and richness to your writing.

Developing an Authorial Voice
