Writing a thesis<\/a> in English as a second language is a remarkable achievement\u2014but it can also feel overwhelming. You\u2019ve done the hard work: researching your topic, analysing your data, and developing your ideas. But when it comes to writing it all down, even strong research can be undermined by simple grammar mistakes. For ESL (English as a Second Language) students, these errors are not a reflection of ability\u2014they’re a natural part of working in another language. That said, in academic writing, grammar really does matter.<\/p>\n

A well-written thesis is not just about what you say\u2014it\u2019s about how clearly and professionally you say it. Grammar errors can confuse your reader, weaken your argument, or distract from the originality of your research. Even small mistakes\u2014like using the wrong preposition or article\u2014can affect how your work is perceived, especially by examiners who are evaluating clarity and fluency as part of academic standards.<\/p>\n

The good news? These errors are fixable\u2014and you\u2019re not alone. Most ESL writers struggle with the same types of grammar issues, and with the right guidance, they\u2019re easy to spot and correct. In this article, we\u2019ll walk you through the ten most common grammar mistakes ESL students make when writing a thesis. We\u2019ll explain what they are, show you how to fix them, and share tips to help you write with more confidence.<\/p>\n

Top Ten ESL Grammar Errors<\/strong><\/h2>\n

1. Subject-Verb Agreement<\/h2>\n

One of the most common grammar problems ESL thesis writers face is subject-verb agreement. In English, the subject and verb must agree in number\u2014singular subjects take singular verbs, and plural subjects take plural verbs. This might sound simple, but it becomes more complex in long or technical sentences, especially when modifiers or unfamiliar noun forms get in the way.<\/p>\n

For example:<\/p>\n

\u274c The results of the experiment was<\/strong> significant.<\/em>
\u2705 The results of the experiment were<\/strong> significant.<\/em><\/p>\n

In the incorrect sentence, \u201cwas\u201d appears to match the word \u201cexperiment,\u201d but the true subject is \u201cresults,\u201d which is plural\u2014so the verb should be \u201cwere.\u201d<\/p>\n

Another tricky area involves collective nouns or phrases with embedded clauses. Consider the following:<\/p>\n

\u274c The committee have<\/strong> decided to postpone the review.<\/em>
\u2705 The committee has<\/strong> decided to postpone the review.<\/em><\/p>\n

Even though \u201ccommittee\u201d refers to a group of people, it is treated as a singular noun in American English, so the verb must be singular (\u201chas\u201d). In British English, treating collective nouns as plural is more common\u2014so consistency matters depending on the academic style you’re following.<\/p>\n

Subject-verb disagreement often goes unnoticed in early drafts because the sentence might “feel” correct when you read it quickly. That\u2019s why it’s essential to double-check every long or complex sentence, especially those that include relative clauses, parenthetical statements, or unusual word order.<\/p>\n

To make proofreading easier, try this tip: identify the main subject<\/strong> and then match it directly with the verb\u2014ignoring everything else in the sentence for a moment. This simple technique can help you spot agreement errors before they weaken your writing.<\/p>\n

2. Article Usage (a, an, the)<\/h2>\n

Articles are a constant source of confusion for ESL writers\u2014especially for those whose native language doesn\u2019t use them. In English, we use a<\/strong>, an<\/strong>, and the<\/strong> to signal whether a noun is general, specific, countable, or uncountable. Knowing which article to use (or whether to use one at all) can be surprisingly difficult.<\/p>\n

Let\u2019s break it down with some examples:<\/p>\n

\u274c She conducted an<\/strong> extensive research into the topic.<\/em>
\u2705 She conducted extensive research into the topic.<\/em><\/p>\n

In this example, \u201cresearch\u201d is an uncountable noun<\/strong>, so it doesn\u2019t require an article. Many ESL writers mistakenly treat it as countable because it seems measurable\u2014but grammatically, it\u2019s not.<\/p>\n

Here\u2019s another common mistake:<\/p>\n

\u274c The participants completed a<\/strong> survey about the course experience.<\/em>
\u2705 The participants completed the<\/strong> survey about the course experience.<\/em><\/p>\n

\u201cA survey\u201d suggests any random survey, but in a thesis, it\u2019s usually a specific instrument you designed. Therefore, \u201cthe survey\u201d is more appropriate.<\/p>\n
