A smaller part or division of a main section, especially in written documents, laws, or organizational structures.
From 'sub-' (Latin for 'under') plus 'section' (from Latin 'secare' meaning 'to cut'). It's a straightforward compound word meaning a cut-under-the-main-section.
Legal documents love subsections because they make rules clearer—instead of one giant paragraph about taxes, you get Section 7: Tax Law, Subsection 7.2: Income Tax, Subsection 7.2.3: Deductions, which makes finding the specific rule much easier.
