* Sub-: This implies a smaller part or division within a larger section, like "subsection."
* Inter-: This indicates something that connects or lies between sections, such as "inter-section" (though this typically refers to the point where roads intersect).
* Cross-: This can suggest something that spans or connects different sections, like "cross-section."
* Trans-: This implies movement across or through sections, such as "trans-section."
Ultimately, the best prefix depends on the specific meaning you want to convey. If you can provide more context about the situation where you need a prefix for "section," I might be able to suggest a more precise option.
