Joining together is a term that can be used to describe the process of combining two or more things into one. FUSING (6 letters) and yoking (6 letters) are two words that can be used to describe this process. FUSING is the process of melting two or more substances together to form a single, homogeneous material. Yoking is the process of connecting two or more objects together, usually with a rope or chain. Both of these processes are used to join two or more things together.
