Seemingly endless is a term that can be used to describe something that appears to have no end or limit. This can be expressed in three different ways: INTERMINABLE (12 letters), VAST (4 letters), and draggy (6 letters). INTERMINABLE means having no end or limit, while VAST implies great size or extent. Draggy, on the other hand, suggests something that is slow and tedious. Together, these words provide an accurate description of something that appears to be never-ending.
