Analysis the Use of Inflectional and Derivational In Students’ Writing

This research uses a qualitative descriptive method with a survey design to analyze the use of morphemic processes, classification and categorization of derivational and inflectional morphemes in students' writing. The research focused on abstracts of scientific articles written by fourth semester students at the Indonesian Catholic University, Santu Paulus Ruteng, with a sample size of 15 students. The 15 students were selected based on their writing results which were in accordance with the criteria. The research instrument is documentation of student writing. The results showed that students' articles mostly consisted of three categories of morphemes that were widely used. First, in the noun category there are 176 occurrences involving the transformation of verbs into nouns or adjectives into nouns. Second, students demonstrate the use of morphemes that change nouns into adjectives. Third, students use morphemes that change adjectives into adverbs. In addition, students also used inflectional morphemes, with the inflectional morpheme “-s” mostly used to indicate the plural form of nouns in their articles. Furthermore, they use the inflectional morpheme “-ed” to indicate the past tense in their writing. Effective use of these morphemes contributes to the clarity and accuracy of students' writing.
