The word Surah comes from the Arabic root word "سُور" (Suur), which originally means "enclosure" or "walled city." In the context of the Quran, it refers to a chapter or section of the Quran. Scholars describe it as a structured set of verses with a specific topic or message.

In older Arabic, the word Surah was used to describe something that was elevated, surrounded, or protected — like a boundary or a strong structure. Based on this meaning, the correct interpretation is that "Surah" metaphorically means a refuge or an enclosed area, much like a walled city that offers protection.

Each Surah in the Quran offers guidance, rules, and spiritual safety — similar to how a strong city protects its people. The Quran contains 114 Surahs, each with a unique name, theme, and purpose. Some are short (like Surah Al-Kawthar), while others are long (like Surah Al-Baqarah).

Important points:
- The word Surah is not literal for "city" but carries the sense of protection or a defined boundary.
- Surahs are revealed parts of the Quran, each serving a unique purpose in Islamic guidance.
- The term reflects order, structure, and spiritual shelter within the Quran.
- The plural of Surah is "Suwar" in Arabic.

Understanding the meaning of Surah helps Muslims appreciate the structure and spiritual depth of the Quran more clearly.
