The term 'Distinct Part' can be broken down into three separate words: SECTION (7 letters), SECTOR (6 letters), and UNIT (4 letters). A SECTION is a distinct part or portion of something, such as a piece of land or a document. A SECTOR is a distinct part of an area, such as a business or industry. Finally, a UNIT is a distinct part of a larger whole, such as a single item or a group of people. All three terms refer to a distinct part of something, whether it be a physical object, an area, or a group.
