This document summarizes a research paper that analyzed the morphosyntactic errors in English essay writing among Malaysian secondary school students. The study examined 10 student essays totaling 50 pages. It found that students made errors with plural marking, subject-verb agreement, tense marking and other grammatical issues. These errors occurred because of differences between English and Malay grammar rules regarding morphology and syntax. The researchers concluded that Malaysian students have not fully mastered certain English grammar rules regarding plural forms, third-person singular verbs and other structures.
