| Resumen: |
Questions surrounding natural and constructed languages have attracted linguistic interest for decades, particularly regarding regularity and language learnability. This dissertation presents a qualitative comparative analysis of the morphology of English and Esperanto. English is examined as a natural language, whereas Esperanto is analysed as a constructed one. The project focuses on both inflectional and derivational morphology, examining how the two languages express categories such as word class, tense, aspect, mood, voice, agreement, plurality and case marking. The findings indicate that English morphology combines productive grammatical patterns with numerous irregular forms that reflect historical linguistic development whereas Esperanto shows a highly regular and transparent morphological system characterised by systematic affixation, along with invariant grammatical endings. The comparison suggests that Esperanto’s planned design contributes significantly to its morphological consistency and facilitates grammar analysis, while English morphology reflects the cumulative effects of historical evolution. At the same time, the comparison shows that morphology alone cannot fully account for language complexity and learnability. |
