Subject-Verb Agreement Errors<\/strong><\/li>\n<\/ol>\nThe subject and verb in a sentence need to agree in number. A singular subject generally takes a singular verb, while a plural subject takes a plural verb. This becomes particularly easy to miss when other words appear between the subject and the verb.<\/p>\n
Incorrect:<\/strong> The list of required documents are on the desk.<\/p>\nCorrect:<\/strong> The list of required documents is on the desk.<\/p>\nThe subject is \u201clist,\u201d not \u201cdocuments,\u201d so the singular verb \u201cis\u201d is required. To avoid this common grammar mistake, identify the main subject before choosing the verb. This is especially useful in longer sentences where additional phrases can make the sentence structure less obvious.<\/p>\n
\n- Incorrect Use of Apostrophes<\/strong><\/li>\n<\/ol>\n
Apostrophes are commonly used to show possession or form contractions, but they are often placed incorrectly. One frequent mistake is using an apostrophe to create a plural noun.<\/p>\n
Incorrect:<\/strong> The student submitted three paper’s.<\/p>\nCorrect:<\/strong> The student submitted three papers.<\/p>\nFor possession, the apostrophe has a different function.<\/p>\n
Incorrect:<\/strong> The students assignment was incomplete.<\/p>\nCorrect:<\/strong> The student’s assignment was incomplete.<\/p>\nWhen a noun is plural and already ends in \u201cs,\u201d possession is usually shown by placing the apostrophe after the \u201cs.\u201d<\/p>\n
Example:<\/strong> The researchers’ findings were published.<\/p>\nChecking whether an apostrophe is being used for possession, contraction, or incorrectly for a plural can help prevent this error.<\/p>\n
\n- Confusing \u201cYour\u201d and \u201cYou\u2019re\u201d<\/strong><\/li>\n<\/ol>\n
\u201cYour\u201d and \u201cyou\u2019re\u201d sound alike but have different meanings. \u201cYour\u201d shows possession, while \u201cyou\u2019re\u201d is the contraction of \u201cyou are.\u201d<\/p>\n
Incorrect:<\/strong> Your going to need more time.<\/p>\nCorrect:<\/strong> You’re going to need more time.<\/p>\nAnother example is:<\/p>\n
Incorrect:<\/strong> I like your explanation because you’re examples are clear.<\/p>\nCorrect:<\/strong> I like your explanation because your examples are clear.<\/p>\nA simple way to check this is to replace \u201cyou\u2019re\u201d with \u201cyou are.\u201d If the sentence still makes sense, \u201cyou\u2019re\u201d is probably correct. If it does not, \u201cyour\u201d may be the right choice.<\/p>\n
\n- Using the Wrong Verb Tense<\/strong><\/li>\n<\/ol>\n
Verb tense tells readers when an action happened. Switching between tenses without a reason can make writing confusing, particularly when describing events in sequence.<\/p>\n
Incorrect:<\/strong> She completed the experiment and writes the results in her report.<\/p>\nCorrect:<\/strong> She completed the experiment and wrote the results in her report.<\/p>\nThe sentence refers to two completed actions in the past, so both verbs should use the past tense. However, tense changes can be correct when the meaning requires them.<\/p>\n
Example:<\/strong> She completed the experiment and now writes the results in her report.<\/p>\nHere, \u201ccompleted\u201d refers to a past action, while \u201cwrites\u201d describes what she is doing now. The key is to make sure every tense change reflects a genuine change in time or meaning.<\/p>\n
\n- Confusing \u201cThere,\u201d \u201cTheir,\u201d and \u201cThey\u2019re\u201d<\/strong><\/li>\n<\/ol>\n
These three words are pronounced similarly but serve different grammatical purposes.<\/p>\n
There<\/strong> generally refers to a place or introduces a statement.<\/p>\nExample:<\/strong> The report is over there.<\/p>\nTheir<\/strong> shows possession.<\/p>\nExample:<\/strong> The researchers submitted their report.<\/p>\nThey\u2019re<\/strong> is short for \u201cthey are.\u201d<\/p>\nExample:<\/strong> They\u2019re reviewing the results.<\/p>\nBecause these words sound alike, relying only on pronunciation can lead to mistakes. Instead, consider the role of the word in the sentence before selecting it.<\/p>\n
\n- Sentence Fragments<\/strong><\/li>\n<\/ol>\n
A complete sentence normally needs a subject and a finite verb and should express a complete thought. A sentence fragment may contain some of these elements but fail to communicate a complete idea.<\/p>\n
Incorrect:<\/strong> Because the results were inconsistent.<\/p>\nCorrect:<\/strong> The researchers repeated the experiment because the results were inconsistent.<\/p>\nThe first example begins with a dependent clause but does not complete the thought. Fragments can occur when writers separate a dependent clause from the main sentence during editing. Reading each sentence independently can help you identify whether it expresses a complete thought.<\/p>\n
\n- Misplaced or Dangling Modifiers<\/strong><\/li>\n<\/ol>\n
A modifier should clearly describe the word or phrase it is intended to modify. When its position creates an unclear or unintended meaning, the sentence becomes difficult to interpret.<\/p>\n
Unclear:<\/strong> After reviewing the report, several errors were found.<\/p>\nThe sentence appears to suggest that \u201cseveral errors\u201d reviewed the report. A clearer version is:<\/p>\n
Correct:<\/strong> After reviewing the report, the researcher found several errors.<\/p>\nPlacing the person or thing performing the action immediately after the introductory phrase usually makes the intended meaning clearer.<\/p>\n
\n- Confusing \u201cAffect\u201d and \u201cEffect\u201d<\/strong><\/li>\n<\/ol>\n
\u201cAffect\u201d is most commonly used as a verb meaning to influence, while \u201ceffect\u201d is most commonly used as a noun referring to a result or consequence.<\/p>\n
Incorrect:<\/strong> The lack of sleep can effect your concentration.<\/p>\nCorrect:<\/strong> The lack of sleep can affect your concentration.<\/p>\nExample:<\/strong> The lack of sleep had a noticeable effect on her concentration.<\/p>\nThere are exceptions to these general patterns, but understanding their most common uses can prevent many everyday errors. When uncertain, consider whether you need a word describing an action or the result of that action.<\/p>\n
\n- Incorrect Pronoun Usage<\/strong><\/li>\n<\/ol>\n
Pronouns need to agree with their antecedents and fit correctly within the sentence. Problems often occur when writers use a pronoun that does not clearly refer to a specific noun.<\/p>\n
Unclear:<\/strong> When the manager spoke to the researcher, he was concerned about the results.<\/p>\nIt is unclear whether \u201che\u201d refers to the manager or the researcher.<\/p>\n
Clearer:<\/strong> The manager was concerned about the results when he spoke to the researcher.<\/p>\nRewriting the sentence can remove ambiguity instead of forcing the reader to determine what the pronoun means.<\/p>\n
\n- Run-On Sentences and Comma Splices<\/strong><\/li>\n<\/ol>\n
A run-on sentence occurs when independent clauses are incorrectly joined without appropriate punctuation or a conjunction. A comma splice occurs when two independent clauses are joined only with a comma.<\/p>\n
Incorrect:<\/strong> The study was completed, the researchers began analysing the data.<\/p>\nCorrect:<\/strong> The study was completed, and the researchers began analysing the data.<\/p>\nAnother option is to separate the ideas.<\/p>\n
Correct:<\/strong> The study was completed. The researchers began analysing the data.<\/p>\nIf a sentence contains several complete thoughts, check whether they have been joined correctly. Breaking a long sentence into shorter ones can often make the writing clearer.<\/p>\n
How to Avoid Common Grammar Mistakes<\/strong><\/p>\nAvoiding common grammar mistakes is less about memorising every grammar rule and more about developing a consistent review process. Start by reading your writing slowly after drafting it. Look specifically for subject-verb agreement, verb tense, pronoun references, punctuation, and commonly confused words rather than trying to identify every possible problem at once.<\/p>\n
It also helps to read sentences according to their meaning rather than simply how they sound. Ask whether the subject is clear, whether the verb matches it, whether each pronoun has a clear reference, and whether the punctuation accurately separates ideas. Reading your work aloud can also reveal missing words, awkward sentence structures, and unnecessary repetition.<\/p>\n
For longer or important documents, an automated grammar review can providec another layer of checking. Trinka Grammar Checker<\/strong><\/a> can help identify grammar and language issues while you write, allowing you to review suggested corrections before finalising your document. The goal is not simply to remove errors but to develop a stronger understanding of the patterns behind them.<\/p>\nFinal Thoughts<\/strong><\/p>\nCommon grammar mistakes can affect clarity even when the underlying idea is strong. Errors involving subject-verb agreement, apostrophes, verb tenses, pronouns, modifiers, and commonly confused words are particularly easy to overlook during everyday writing.<\/p>\n
The best approach is to combine grammatical awareness with careful revision. Understand why a correction is needed, review sentences in context, and use grammar-checking tools as an additional review step. Over time, recognising these patterns becomes easier, making your writing clearer, more accurate, and easier for readers to follow.<\/p>\n","protected":false},"excerpt":{"rendered":"
