What does subsection mean?
A subsection is a smaller division within a section of a document, discussion, or organized body of information. It functions as a subordinate heading and usually contains material focused on a narrower aspect of the section's overall subject. Subsections are especially common in legal texts, academic writing, technical manuals, reports, and reference works, where they help readers navigate complex material by dividing it into clearly labeled units. The word is also used more broadly for a smaller part of a larger subject or system. Unlike a section, which is typically a major division, a subsection occupies a lower structural level. Its name combines the prefix sub-, meaning “under” or “beneath,” with section, making clear that it belongs to a broader division.

Where does subsection come from?
The word was formed in the 19th century from the combining form sub-, meaning “under” or “secondary,” and section. Both elements are Latin in origin: sub- comes from sub, meaning “under,” while section comes from secare, “to cut.” The word thus literally suggests a division made beneath or within a larger division.
