Abstract:
This study aimed to identify and analyze the common grammatical errors present in the persuasive essays of Grade 10 learners and to determine their implications for English language instruction. Using a qualitative research design, specifically content analysis, the study analyzed the written compositions of 34 Grade 10 learners from Baringcucurong National High School during the school year 2024-2025. The corpora consisted of 68 persuasive essays ranging from 150-200 words, written in response to two essay prompts. The analysis followed the steps of error analysis proposed by Corder, which include the identification, description, explanation, and evaluation of errors. The identified errors were categorized based on the classification of Runkati, which includes word level and sentential level errors. The findings revealed several recurring grammatical errors in the learners’ persuasive essays, particularly incorrect word choice, incorrect use of prepositions, incorrect use of articles, incorrect use of punctuations, subject-verb disagreement, and incorrect word order. These errors were found to affect clarity, coherence and persuasiveness of the learners’ written outputs. The occurrence of these errors suggests that the learners still experience difficulties in applying fundamental grammatical rules in written communication, which may be influenced by limited vocabulary, insufficient mastery of gramma structures, and interference from the learners’ first language. The results highlight the need for more focused grammar instruction integrated with writing activities in the classroom. The study recommends the implementation of targeted instructional strategies, continuous writing practice, and guided feedback to help learners improve their grammatical accuracy and overall writing competence.
