Translating Metaphor In Qur'an Into English: Strategies And Challenges, Sultan Samah A Almjlad

Journal of Arabic Sciences and Humanities

Metaphor, or istiʿāra in Arabic, is one of the most prevalent rhetorical devices used in Qur'anic discourse. The Qur'an employed metaphor to convey meanings not immediately apparent on the surface of the text, yet significant. Thus, translating these metaphors into English was extremely difficult due to linguistic and cultural differences. Three well-known English translations of the Qur'an by Ali, Pickthall, and Abdel-Haleem were examined in this study. The study adopted a theoretical approach depending on metaphor translation and Newmark’s conceptual metaphor theory. To achieve its goals, the study was based on 40 Qur'anic verses in Arabic, as only 13 metaphors …

Are Uninterpretable Features Unlearnable? Revisiting The Interpretability Hypothesis In Second Language English Acquisition, Salma Musleh Alqahtani

Journal of Arabic Sciences and Humanities

The Interpretability Hypothesis (IH) predicts that uninterpretable features absent in the L1 become inaccessible in adulthood, whereas Full Access theories maintain that Universal Grammar (UG) remains available. Despite extensive research, it remains unclear whether elevated resumption acceptance in L2 learners reflects a representational deficit or processing-based strategies, and no study has examined the role of working memory in this distinction for Saudi learners. This study tested whether Saudi learners of English show L1 transfer in accepting resumptive pronouns (RPs), grammatical in Arabic but ungrammatical in English, and whether this reflects representational deficits or processing limits. A total of 164 Saudi …

Type V Collagen Controls Decidual Extracellular Matrix Organization And Angiogenesis During Embryo Implantation, Joseph Boyd, John P Lydon, Shanmugasundaram Nallasamy

Faculty, Staff and Students Publications

Extracellular matrix (ECM) remodeling and angiogenesis are essential processes underlying endometrial decidualization during embryo implantation. Fibrillar collagens, the major structural components of the ECM, form the architectural framework of the decidua and undergo dynamic reorganization during this process. However, the functional role of type V collagen—a key regulator of collagen fibrillogenesis—remains undefined. Here, we demonstrate that Col5a1 is highly expressed in decidual stromal and endothelial cells of the mouse uterus. Conditional deletion of Col5a1 leads to progressive uterine hemorrhage beginning at gestation day 8, culminating in complete embryo resorption and pregnancy loss by day 12. Col5a1-deficient decidua exhibits severe …
