Stamps with different designs that are attached to one another are called "Se-tenant" by stamp collectors."Se-tenant" translates from French as meaning "holding together or "joined together". In French the word is pronounced "seh-tah-NOHN," while many American collectors pronounce it "seh-TEH-nent." The term is used to describe attached stamps that are different from one another. Se-tenant stamps began as issues of separate designs that were simply attached to one another which may be either one or more. They may have their attachments in horizontal or vertical strips or both types in one block of four. Sometimes, they may have attachments even at corner points.  Moreover, we also find issues where the stamps are part of a larger continuous design.

Se-tenant Stamps can be available either from regular sheets or Sheetlets and from Miniature Sheets. Collectors around the world are fascinated by the various combinations of se-tenant stamps.The occurrence of se-tenant stamps has increased dramatically during the past 30 years. For many years, whenever a sheet of stamps was printed, every stamp on the sheet would have the same design. However now, Se-tenant stamps or labels are printed from the same plate and sheet and adjoin one another. They differ from each other by design, color, denomination or overprint. They may have a continuous design too.There are differing ways of preparing a se-tenant sheet.
