Se'if katan
Se'if katan (Hebrew: סעיף קטן, Rashei teivot: ס"ק) is a term for a subsection in the halachic literature. In the standard format for commentaries on halachic works, each se'if (section) of the original work is split into a number of separate se'ifim; such se'ifim are known as se'if katan.
