Page "United States Code" Paragraph 12

The Code is divided into 50 titles ( listed below ), which deal with broad, logically organized areas of legislation.

Titles may optionally be divided into subtitles, parts, subparts, chapters, and subchapters.

All titles have sections ( represented by a §), as their basic coherent units, though sections are often divided into ( from largest to smallest ) subsections, paragraphs, subparagraphs, clauses, subclauses, items, and subitems.

Congress, by convention, names a particular subdivision of a section according to its largest element.

For example, " subsection ( c )( 3 )( B )( iv )" is not a subsection but a clause, namely clause ( iv ) of subparagraph ( B ) of paragraph ( 3 ) of subsection ( c ); if the identity of the subsection and paragraph were clear from the context, one would refer to the clause as " subparagraph ( B )( iv )".
