Multi-body parts are models made within a SOLIDWORKS part file that contains more than one separate body. Hence, they are called multi-body parts.

Note that the difference between the following two figures is that the right-hand one had an extrusion cut that separated the large triangle (one solid body) into two triangles (two solid bodies):
