This study investigates the syllable-based classification of bound morphemes in English words, with the aim of systematically identifying, categorizing, and analyzing the inflectional and derivational bound morphemes present in a corpus of 102 English words drawn from authentic political and social discourse texts. The words are distributed across three syllabic categories: 25 two-syllable words, 51 three-syllable words, and 26 four-syllable words. Employing a descriptive qualitative approach and purposive sampling, the research applies the Item-and-Arrangement (IA) morphological analysis model to decompose each word into its constituent base and bound morpheme(s). The findings reveal a clear morphological gradient corresponding to syllabic length: two-syllable words are predominantly characterized by inflectional morphemes (64%), particularly -ing, -ed, -s, and -ies, three-syllable words exhibit increased derivational morpheme diversity (47%), including suffixes such as -al, -tion, -ment, -ize, -ity, and -ence, and four-syllable words are overwhelmingly derivational (65%), featuring both complex suffixes such as -ion, -cy, -ial, -ize, -al, -ly and productive prefixes such as mal-, non-, un-, re-. Morpheme stacking the co-occurrence of derivational and inflectional morphemes within a single word is found in 17 words (16.7%), consistently following the hierarchical principle that derivational morphemes occupy inner positions and inflectional morphemes occupy outer positions. The study contributes a syllable-stratified morphological taxonomy that bridges descriptive linguistics, second language vocabulary pedagogy, and computational morphological analysis.
