Academic language is a fundamental element in the success of any master’s thesis, as it is the vessel through which the researcher’s scientific and intellectual effort is presented. Despite the importance of scientific and methodological content, the presence of recurring linguistic errors can diminish the value of the thesis and negatively affect its evaluation by supervisors and examination committees. Therefore, many graduate students ask: What are the common linguistic errors in master’s theses? And how can they be avoided from the early stages of writing.
The danger of linguistic errors lies in the fact that they are not merely formal slips, but may reflect a weakness in scientific accuracy or a lack of mastery of academic research tools. Repeated spelling or grammatical errors can distract the reader, reduce the clarity of ideas, and sometimes even lead to misunderstanding of results or the theoretical framework. Additionally, some universities emphasize linguistic safety as one of the criteria for final acceptance of the thesis.
This article aims to highlight the most common linguistic errors inmaster’s thesesexplaining their causes and effects, and providing practical guidelines to help researchers improve their academic language. The focus will be on spelling, grammatical, and stylistic errors, as well as translation and documentation errors, in a clear style suitable for master’s students from various disciplines.
